She also wears a white Z-Ring with a red strap that once belonged to her father with an Icium Z which she got after helping out the Alolan Sandshrew in the episode Not Caving Under Pressure
Later in "Family Determination!", when she and Gladion were going to rescue their mother Lusamine, Lillie wears a different outfit; her "Z-powered form" from the games consisting of a white short-sleeved hoodie, white pleated skirt, white socks and matching sneakers. She no longer wears her large white hat and her hair is tied into a high ponytail. She also carries a pink backpack on her back with both of her outfits. Later in "The Professors' New Adventure!", she returns to her original style. However, during the Alola league and her battle against her brother Gladion, Lillie wears this outfit until the League was over.
As a member of the Ultra Guardians, Lillie wears a pink and white Ultra Guardian uniform with light pink accents as the edge of her short sleeves, collar, and the in lines of her uniform is black with matching pink gloves. She retains her hairstyle from her second outfit.
In "Dummy, You Shrunk the Kids!", she retains her hairstyle from her second outfit while wearing her original style. She also tied up her hair when she was helping out at Mallow's family restaurant in "A Recipe for Success!".
For her goal to find her lost father, Lillie wears a white vintage dress with light blue accents and a light green ribbon around her waist. Her hat contains a light blue ribbon hem and a white lily on the knot of the bow. She wears her hair with the braids tied at the back with a light green ribbon. She wears her father's Z-ring on her left wrist.
Lillie is a girl who loves Pokémon but was unable to touch them after moving away to another mansion with her mother and brother after an accident with an ultra beast. Upon her return, she inexplicably was frightened of Pokémon and will either jump away or freeze like a statue though some feel that she is terrified of them. Despite her fears, Lillie loves to leave food out for various Pokémon to eat. Her knowledge of Pokémon is top notch. Lillie was so scared of touching Pokémon that she had to wear a suit to ride Pokémon. Lillie decided to take one step at a time to get over her fear of touching Pokémon. Initially, she was only comfortable with her Alolan Vulpix Snowy, but managed to touch Ash's Pikachu without hesitation later on, and even ride a Stoutland without repercussions. However, after her memories came back regarding Silvally saving her, she was able to touch all Pokémon without being scared.
She has a keen eye to detail which was shown when she noticed the details in the recording tape of Rotom's and proved Kiawe's innocence. Lillie is rebellious towards her mother Lusamine upon their reunion and like Brock, she also shows her anger and disdain because of her ditzy behavior and also causes a fall out between the two and became annoyed when she keeps doting on her. After rescuing their mother from the Ultra Beasts onward, Lillie grew more confident in herself shown in "Not Caving Under Pressure!" when she teamed up with medium-sized wild Alolan Sandshrew in a Double Battle with Snowy against a wild Tyranitar.
Though she had a problem with touching Pokémon at first, Lillie compensates that problem by learning more about them. She shows a lot of knowledge in certain topics. In addition, she also makes quality Pokémon food. Lillie has shown both her Pokémon battling skills and tactics due to watching her friends battle a lot of times. Also, Lillie has shown to be able to use Z-Moves.
When Lillie was younger, she and her mother were very close, but once Lusamine became distracted with her increasingly busying work at the Aether Foundation, she often made decisions without considering her daughter’s feelings, causing a strain in their relationship. Lusamine is very fond of Lillie and often treats her like a little baby, which greatly embarrasses her daughter and causes her to frequently get annoyed at her. However, their relationship improved once Lusamine realised how much she had been neglecting Lillie’s feelings. After she saved her from a Nihilego in Ultra Space, Lillie felt close with her mother again. She also comforted Lusamine over her grief from losing Mohn, showing how much she truly cares for her mother. Lillie joined her mother on a journey to find her long lost father alongside Gladion.
Mohn is Lillie's father but she believed that he passed away when she was still a baby. However, Lillie and Gladion found out that their father was still alive as they search for info about him due to not knowing much about him. She cares about her father and felt a bond with him when she found his Z-Ring along with discovering Magearna that he found and bought for her.
Growing up, Lillie and Gladion shared a close sibling relationship with each other, and are often shown playing together in flashbacks. However, after a Nihilego attacked Lillie and she developed a fear of touching Pokémon, Gladion left to become stronger to defeat all Ultra Beasts, and although this decision was made out of a desire to protect Lillie, it also caused them to grow distant, with Lillie becoming confused by how serious and cold her normally kind brother had become when he returned. Over time, as Lillie gets over her fear of Pokémon and the two decide to look for their father together, the relationship improves and they become close once again. Gladion appears to be impressed by how much stronger Lillie has become over time, and Lillie is very supportive of her brother, as shown when she twirled around in excitement when he made it to the semifinals of the Alola League. Lillie and Gladion accompany their mother on a journey to find their long lost father.
Hobbes is more then just a family servant to Lillie but a close friend to her as he takes great care of her. Lillie has known Hobbes her whole life and consider him a father-figure. Also, Hobbes does a lot for Lillie and her family. Lillie parts ways with Hobbes for a while when she and her family left to go on a journey to find her long lost father.
Lillie shares a close friendship with Lana as they do a lot of girl activities together. They spend their most time together and they even have Mallow join them from time to time. Lillie would do anything to help Lana when she needs it. Also, Lillie and Lana are classmates at the Pokémon School. At times, Lillie gets annoyed with Lana's jokes. They part ways when Lillie left with her family to go look for her long lost father while Lana stays in Alola before setting off to go fishing with her dad.
Lillie is very good friends with Mallow and they do a lot of girl stuff together with Lana joining them in their activities. Also, Lillie would help Mallow as she looks out for her just like she looks out for her. Lillie and Mallow are also classmates at the Pokémon School. They went their separate ways when Lillie left for a journey with her family while Mallow stays in Alola to improve her families restaurant.
Kiawe is one of Lillie's good friends and classmates at the Pokémon School. Lillie would help Kiawe and has his back when he needs it, shown when she helped him protect his family farm from being turn into a resort hotel. They part ways when Lillie decided to go on a journey with her family while Kiawe stays in Alola to finish his Island Challenge.
Sophocles is Lillie's other good friend and classmate at the Pokémon School. Lillie would encourage Sophocles to do his best, shown when she came to support him in the Vikavolt race. They part ways when Lillie and Sophocles left Alola as she was on a journey with her family to look for her long lost father while he left to make his dream a reality in Hoenn with his cousin, Moylane, accompanying him.
Ash is one of Lillie's best friends as he looks out for her and is always concerned for her safety. When Lillie first met Ash, she instantly trusted him as she felt comfortable to hide behind him when a Tarous approached her, which shows how they were able to hit off their strong friendship right away. Lillie and Ash were also classmates at the Pokémon School. Also, Lillie was inspired by Ash to take action of getting over her fear of touching Pokémon, which got her to touch a couple of them. However, after becoming scared of touching Pokémon again and became depressed about it, Lillie was not only inspired by Ash's upbeat attitude when he cheered her up but he also encouraged her to not give up on getting over her fear of touching Pokémon once and for all.
Lillie is very grateful to Ash as she wouldn't remember her past and get over her fear of touching Pokémon without his help. Also, Ash was the biggest help in getting Lillie and Gladion's mother back from Ultra Space with their other friends assisting in the rescue as well. Like Serena, Lillie admires Ash and looks up to him as she learned a lot from him. In addition, Lillie would get helpful advice from Ash and he even helped her perfect her Z-Moves. Lillie and Ash share a common love for Pokémon, excitement for adventure and their willingness to help people or Pokémon for various reasons. Although sometimes, Lillie does get annoyed with Ash's habits. Lillie gives her full support for Ash whenever he is in a Pokémon battle or competition he participates in. They part ways for a very different journey but not before telling each other how glad to have met and thanked each other for everything they did for one another.
Lillie took care of Snowy, Vulpix, since she was an egg, but when she hatched she became her partner Pokémon. However, after spending the day bonding with her first Pokémon, Lillie ended up getting another best friend in Snowy. Lillie enjoys holding Snowy in her arms as they like to be together no matter what the activity was and would always have her outside her PokéBall. Also, Lillie would do anything to keep Snowy safe from harms way and she would do the same for her. Lillie brought Snowy with her on her journey with her family to find her long lost father.
Magearna is a Mythical Pokémon Lillie is taking good care of, although it was inactive when they first met. Magearna was meant to be a present for Lillie from her father Mohn, however he couldn't activate it. Lillie then decided to activate Magearna herself so she could get to know it and become friends. Through hard work and the love she has for her family, Lillie was able to reactivate Magearna and happily hugged it as she got her wish to be its friend. Lillie even had Magearna accompany her and her family on their journey to find her long lost father.
Lillie has a wealthy family as her mother owned the Aether Foundation along with an older brother named Gladion. Lillie became close friends with the family butler Hobbes and her mother's Pokémon. Also, Lillie had a lot of fun moments with her family but then her mother got busy with her work thus couldn't entirely spend time with them. Her father Mohn later went missing in an Ultra Wormhole when she and Gladion were very young, so both had a blurry remembrance of him.
At one point, Lillie was taken by her mother Lusamine from her mansion on Melemele Island. Then one day, Lillie was in the basement of the Aether Foundation where she was looking for her mother then she saw Faba opening a Ultra Wormhole where an Ultra Beast, Nihilego, came out and attacked her. When Gladion arrived, as he was looking for her, he could only observe the event, as he was not brave enough to defend her, and Lillie was terrified. Suddenly, a Silvally arrived, which defeated the Ultra Beast which also saved Lillie in the process then caught her when she was falling, after passing out. While Lillie lost her memory of the encounter and became scared of Pokémon, Gladion took the Silvally as his own Pokémon, and swore to protect his sister. When she came back to Melemele Island, Lillie enrolled to the Pokémon School there, as she wanted to learn more about Pokémon despite her fears.
Pokémon the Series: Sun & Moon (series)
Lillie was watching over the group's Pokémon, Togedemaru, Popplio and Bounsweet, as Mallow, Sophocles and Lana were riding Tauros. Ash went over the fence, so Lillie tried to warn him about to Tauros, but was too late. Ash was trampled over the Tauros, but stated he was fine since he had Tauros back at home. Sophocles was interested how Lillie couldn't touch Pokémon; Lillie denied that, claiming she only touched Pokémon once she knew it was safe to do so. Later, Lillie watched as Ash and Kiawe dealt with Team Skull grunts. That next day, Lillie gave a recipe to Mallow for some Pokémon food. Mallow accepted the recipe, causing her Bounsweet to jump in happiness. Lillie was terrified by Bounsweet, even if she did claim she loved Pokémon if she liked touching them. When Ash arrived, as he enrolled in the school as well, and showed the Z-Ring, given to him by Tapu Koko. Lillie recalled that Tapu Koko was known to give certain gifts to others if it liked them, but it could also punish others. During Samson Oak's class, Lillie noticed the Alolan Exeggutor was much taller than one found in other regions. Ash went to check Alolan Exeggutor, though Lillie tried to warn him that Exeggutor's tail could hit him. Ash was knocked away and Lillie told him this, which made Ash question why didn't she say anything earlier. The next day, Lillie watched as Ash competed in the challenges her friends made for him. Just as Ash was to face Professor Kukui in the final challenge, the group had a meal from the recipe Lillie gave to Mallow. During the meal, Tapu Koko arrived and snatched Ash's hat. Ash went into the forest, so Lillie and others went after him. In the forest, they watched as Ash's Pikachu battled Tapu Koko, as well as Ash using the Z-Ring to activate Gigavolt Havoc. In the end, Ash decided to take on the Island Challenge, a decision Lillie supported. Once Ash obtained the Rotom Pokédex, Lillie was amazed by the device. Along with her friends, Lillie went with Ash, who wanted to catch some Alola Pokémon. Lillie watched as Ash's Pikachu battled Mimikyu, as well as how Team Rocket appeared to steal their Pokémon and were dragged away by a Bewear. Ash's Pikachu was hurt during his battle against Grubbin. During the battle, Grubbin emerged near Lillie, who was terrified by it and hid behind Mallow, claiming she only loved Pokémon as a topic to study. Ash and Mallow went to the Pokémon Center, while Lillie, Sophocles, Kiawe and Lana went to report to Professor Kukui what happened. Since the group was going to fishing, Lillie planned on how to touch Pokémon during fishing. Popplio went into her lap, which made Lillie terrified. Lana quickly took Popplio back and apologized. The next day, before started fishing, Lillie put on a protective suit, allowing her to sit on a Lapras. Lillie fished out a Milotic but was too terrified to catch it. Ash was sent to help her but was tackled by Milotic, while Lillie's rod's thread was cut off. Lillie also watched as Lana and Ash confronted Team Rocket and was happy Popplio managed to save the Poké Ride Lapras and Wailmer. She also agreed that Popplio was "the MVP" of the day. Lillie was with her classmates at the School. Ash spoke that a Litten stole his lunch. Lillie asked him how he would get his revenge on it and was surprised that he would catch it.
Before the class started, Sophocles' Togedemaru was overexcited and leaped around, nearly hitting Lillie, who was pulled by Mallow. Lillie thanked Mallow and stated she could touch Pokémon if she was really certain if it was safe. Lana reminded her she never actually touched a Pokémon at school, so Ash and Kiawe were certain she would find some courage. The class was called by Professor Kukui, who led them to Samson Oak's office. He showed them two eggs, from which one of them the class had to take care of. Lillie chose the blue egg because of its cute flowery pattern. Per Mallow's offer, Lillie went to touch the egg, but was scared when it started to move. Since Mallow had to work at her cafeteria, Ash decided to accompany Lillie and take care of the egg. The limousine arrived, which startled Ash, even more by the mansion where Lillie lived. The butler, Hobbes, asked of Ash to let Pikachu stay in the courtyard, but Lillie permitted Ash to hold onto Pikachu, since he was her friend. After showing her room, Lillie read a book about eggs and placed the blue egg on some pillows on a sofa. Ash noticed a picture of Lillie and her family; Lillie stated her mother and brother are absent. Noting Lillie held a Lillipup, Ash wondered why couldn't she touch Pokémon now. After being explained by Hobbes the reason, the group had a meal and, after that, Ash wanted Lillie to touch Pokémon. However, his Pikachu, Rowlet and Rotom were moving, which scared Lillie. Regardless, she showed she could feed other Pokémon and gave some food for a Butterfree, who ate it from a bowl. Since Ash wanted to train as well, Hobbes volunteered to be his challenger. Lillie watched their battle and just as she went to check the egg, a Salandit tried to steal the egg, which she protected. Fortunately, Ash, Mallow and Hobbs arrived in time to stop Salandit, who was being chased off by Ash's Rowlet and Hobbes' Oricorio. Ash and Mallow comforted Lillie and pointed out she actually touched the egg, which made her really happy. Pikachu went to congratulate her, but Lillie was still frightened of other Pokémon. Regardless, Lillie promised to watch over the egg.
Hearing Mallow say how glad she was that she was taking care of the egg, Lillie was nervous what would happen if the egg broke, but Mallow reminded her she gained courage, since she couldn't touch the egg at first. Both of them noticed Ash was pondering some thoughts. Ash explained to the class that Hala asked him how would he deal with the Rattata and Raticate problem without fighting. Lillie believed they could find more about Rattata and Raticate's ecology, which the Rotom Pokédex explained out loud. The class soon learned the answer lied in Yungoos and Gumshoos, which were Rattata and Raticate's natural enemies. Lillie, along with her classmates, was at the party to celebrate Ash's Grand Trial of Melemele Island victory. Lillie spent a day at the beach with her classmates. She had Kukui watch over her egg, as she went into the sea with Mallow. She played in the sea with her friends before Kukui asked of them to observe the Pokémon and their habitats. Later on, she continued playing with her friends, with Popplio's bubble serving as a balloon. During the Pokémon Pancake Race, Lillie was with Professor Kukui, as they both cheered for their classmates. Occasionally, Lillie also noticed her egg was glowing a bit. That next day, Lillie yelled out as the egg, which she nicknamed "Snowy", started shining. Lillie and her classmates watched as the egg hatched into an Alolan Vulpix.
Lillie told the Vulpix how happy she was that she get to finally meet her then tried to touch the Fox Pokémon but was still afraid. After witnessing Samson Oak egg hatched into a red Vulpix, Lillie watched as the Alola Vulpix she nicknamed Snowy refused to play with the other Pokémon. Lillie became surprised when her friends say that she should be Snowy's trainer. However, Lillie was unsure and was still scared but Snowy went to her as she really likes her. Seeing that she really wants to be her Trainer, Lillie decided to have Snowy be her partner then was given a Poké Ball by Professor Kukui. Lillie threw the Poké Ball, which fell on Ash's head, hitting him. Still, the Ball fell on the floor and Snowy let itself be captured. Lillie sent Snowy out and went to touch it, but was still afraid. Still, Lillie friends encouraged her to keep trying, as Ash stated he always wanted to be friends with his Pokémon. Kukui also explained there were different bonds between people and Pokémon. After school was over, Lillie asked of her driver that he could go home, as she wanted to walk with her Snowy around town. She explained she and Snowy do not know much about each other and wanted to meet each other better. The two went around town and Lillie admitted she was afraid of Pokémon, but wanted to change that, since she loved Snowy. To start, Lillie wanted to buy a malasada for Snowy. The two went into a restaurant, where Snowy chose a sweet to eat. Once done, the two continued walking until facing Team Rocket. Lillie and Snowy tried to flee, but since they were pursued, Snowy fired Powder Snow on the ground. Team Rocket tripped over the ice, giving Lillie and Snowy more time. However, the two were cornered. James sent Mareanie to fire Sludge Bomb, but was countered by Snowy's Powder Snow. Team Rocket claimed she should give Vulpix away, as there was no chance of winning. Lillie refused and her Snowy was hit by Mareanie's Sludge Bomb. After Snowy was blown away, Lillie with no second thought jumped after her partner and held it. Fortunately, the two were saved by Ash, whose Rowlet used Leafage to lower them down. Seeing that Snowy wants to finish what they started together, Lillie had her partner freeze Team Rocket with Powder Snow. After Team Rocket was taken away by Bewear agian and their troubles were over, Lillie realized that she is holding Snowy without being scared which pleases both Mallow and Ash. That next day, Lillie showed to the class she could hug her Snowy, but was still afraid of other Pokémon like Togedemaru. Still, Lillie wanted to continue seeking the courage to befriend other Pokémon with her friends and partner support.
Lillie listened to Ash, who explained how Rockruff came injured the other day and was told Rockruff was a wild Pokémon that Kukui took into his house. The next day, Lillie watched as Ash trained Rockruff and was surprised Ash took Rockruff's Rock Throw attack. One day, Ash lost his Electrium-Z. This terrified Mallow, Lana, Lillie and Sophocles, as the latter explained that Kiawe would get mad at Ash and even punish him for losing such an important item. As Kiawe came, Lillie and others tried to distract Kiawe, then went away. The group went outside, where Lillie watched as Lana had her Popplio emit a bubble for Snowy. Lillie was glad for Snowy, who felt very excited at the fun it was having. Ash continued to avoid Kiawe until Pikachu and Rotom arrived. Rotom accused Kiawe of being the culprit, which shocked the class. Rotom played a video, in which Lillie saw that Ash placed something in his pocket. Ash recalled after his fight with Kiawe the other day, he left the crystal at home, which got stuck in Rotom's wig. In the end, Lillie watched as Kiawe chased Rotom for accusing him and agreed with Sophocles. Lillie and four of her friends went to Aina Cafeteria to taste Mallow's Mythic Alolan Stew, but got electrocuted; Mallow said she told Pikachu to electrify the stew. As Mallow's father explained more about the stew, Mallow explained she actually needed some yellow nectar. Lillie noted how it wasn't the time for the season of the yellow nectar. Mallow invited the group for another stew, using the yellow nectar she and Ash were looking for. Lillie, like his friends, liked the stew. Lillie watched as Ash and Rockruff fought Hiroki and his Mudbray. As Ash announced he would want to battle against Tapu Koko, Lillie admired his determination. She reminded them Tapu Koko was an Electric-type and Fairy-type Pokémon. The next day, she watched as Ash and Pikachu fought against Tapu Koko. Like others, she was shocked when Ash jumped off the cliff to save Pikachu, but was relieved that Tapu Koko saved both of them.
As the class visited the mall, Lillie was browsing the shop with her Snowy. After mentioning the girls would like to visit the Alola Sunrise shop for numerous accessories, Sophocles, Kiawe and Rotom immediately ran off, leaving Ash to hang out with the girls. After Lillie and the others finished shopping, they wondered why Ash claimed they done their shopping in perfect timing. Lillie was with Sophocles when they saw trouble on the beach. They, along with Mallow and Lana, arrived to Kiawe, who informed them Palossand captured Ash and Litten, being furious that the shovel it had on its head was sent into the ocean. While Popplio and Pikachu searched for the shovel, Lillie and the rest sneaked behind Palossand. Kiawe distracted Palossand by having Turtonator and Charizard attack, while Lillie had Snowy use Powder Snow on Palossand to freeze it. Since Snowy didn't have enough power, Lillie and her friends started to make wind by swinging things. This powered up the Powder Snow and froze Palossand, though Snowy became too exhausted to do anything else. Still, Ash, Litten and Rotom were rescued, and Pikachu and Popplio returned the shovel to Palossand. Lillie was present at the Visitation Day of the Pokémon School, with her butler, Hobbes, being by her side. Ash introduced them to her mother, who was surprised Hobbes addressed her son as "mister". During Ash's presentation, when Ash started to make gestures of Pokémon like Samson did, Lillie became highly suspicious of Ash. Kukui took Rotom out of Ash's shirt, and let Ash continue with his own words; Ash gave an inspiring presentation, which amazed his classmates and the people that visited the school. Later, Lillie, with her classmates, found the Team Skull grunts causing trouble at the schoolyard. Still, she watched as Ash and his mother battled the grunts and won. Delia also called the group to repair the damage others made, and Lillie joined in. Lillie watched as Ash and Kiawe demonstrated their Z-Moves. Later, Kukui showed the class the replicas of the Z-Crystals, and taught the class how should they move while executing the Z-Move. Lillie and the others repeated their movements, being interested in them. Sophocles, who had few days before moving away, gave his classmates maps of his favorite places. While Lillie showed her gratitude Lana was suspicious of Sophocles, who usually tried to hide his sweets from other people, a fact Mallow confirmed. After school was over, Lillie and her friends confronted Sophocles, who revealed he was moving away. Everyone was in shock, and decided that Sophocles should have a good time so he would remember everyone. Mallow claimed there was no time for feeling down, and took them all to her Cafeteria. The next day, during the farewell party, Mallow took Sophocles inside, along with Kiawe, Mimo and Lillie. Sophocles, however, wanted to explain the problems. Lillie admitted she was grateful that Sophocles was the first one that welcomed her to the school and showed her around. When Ash came to the Cafeteria, Mallow scold him for being late, though Ash brought a Charjabug to Sophocles as a present. Sophocles, who was touched by his friends' dedication, cried and told others that it was a misunderstanding he was moving away and that he would remain at the School. Lillie and others, however, were relieved Sophocles would remain, who thought his friends would abandon him for not saying the truth earlier.
After the school was over, Lillie found her brother, Gladion, at a square. She met up with Ash, and introduced him to her brother, Gladion, and showed she could touch Snowy, who hatched from the egg. Gladion claimed she should take care of it and left, troubling Lillie for such a short, cold answer. Ash wanted to challenge Gladion, who noticed Ash had a Z-Ring. Lillie told Ash got it from Tapu Koko, and fought against that Pokémon, making Gladion at least consider Ash's challenge. Later, at the mansion, Lillie explained to Ash Gladion was her brother, who left about a year and half ago. She explained he wanted to train on his own, to reflect on his Pokémon, and noted how her brother had changed. Hobbes recalled how Gladion found an injured Eevee and helped it to be cured at the Pokémon Center, while Ash recalled how Gladion did wish Lillie to bond with Snowy by taking care of it. Lillie saw both of them were correct in that. The next day, Lillie wanted to approach her brother, who fought against Ash. Gladion left, making Lillie annoyed that he left so sudden once more.
Lillie was at School when Kukui announced the class would be playing Pokébase, with the famous player 'Olu'olu as their teacher. Lillie was the Right Fielder of Kiawe's team. As Pikachu hit the ball Kiawe threw to him, Lillie went to catch the ball. She started to panic, and her Snowy caught the ball, which Lillie was grateful for. Later, Ash's team won, and Lillie clapped for their victory. Since Team Rocket appeared, some of the classmates had a Pokébase match with them, with Lillie observing the play. She did note that Snorlax rarely ever moves, and had difficulty in playing the Pokébase. In the end, Lillie was glad that 'Olu'olu's Snorlax brought them the victory and was surprised that Bewear appeared and snatched Team Rocket away. Lillie was camping out with her classmates, and was preparing curry for the lunch. Since she had trouble lighting the cooker on, Litten used Ember to activate it. Lillie thanked Litten for that, but the fire was soon doused by Snowy, who wanted to serve Lillie. Lana terrified the group with a story how a certain traveler went into the forest they were currently in and fell asleep, then woke up being very skinny. Lillie and Mallow were terrified of something in the bush, which turned out to be just Ash's Rockruff. While having the lunch, Lillie admitted this was her first camping trip, and told she brought a lot of Potions, Repels, pajamas and dresses. After the lunch was over, Lillie was relaxing by the river with Snowy. However, after some time had passed, Lillie tried to find her Snowy, but was put to sleep, along with everyone else. Later, Ash and Sophocles, who were drained, came to the camp, they saw their classmates, except Lillie, were drained, too. Lillie watched as her friends massively ate the curry. The group noted everyone was put to sleep by a strange figure, and when they woke up, they were very hungry. Rotom blamed Lillie, who was the only one that was not hungry, but others pointed out she couldn't have made them hungry. Suddenly, the group saw a white figure, who emitted light particles and lulled everyone to sleep. When they woke up, everyone but Lillie felt hungry again, and found the figure was a Morelull. Lillie realized she was unaffected as the Repel did keep away Morelull from her, avoiding being drained. The Morelull was slightly sleepy, and hopped away to a doll. Lillie was embarrassed, as it was her doll that she slept with. Ash had Morelull drain his energy, while Ash ate the curry to replenish himself, astonishing Lillie for that feat. Later, the group followed Morelull, who joined others of its kind to a giant tree, where every Morelull evolved into a Shiinotic. The Shiinotic Ash befriended earlier thanked them and pulled them all to sleep. The next morning, everyone woke up and saw they were not hungry anymore, as Shiinotic returned their energy back. However, Lillie was unaffected because she had Pokémon spray, making the Pokémon keep away from her and grew hungrier.
Lillie and Snowy watched the other classmates' Pokémon race around the classroom and the winner was Pikachu. Kukui came and stated their homework was to trade Pokémon and take care of it for two days. Lillie and Ash traded their Pokémon, as Rotom assured her that it knew Snowy's favorite recipes of Pokémon food. Lillie was reassured; she bid farewell to Ash and Snowy, then went with Pikachu inside her car. At the mansion, Lillie told to Hobbes her homework was to take care of Pikachu. While she knew Ash would take good care of her Snowy, she was uncertain if she could do the same to his Pikachu, who ate the sweets she had prepared. Lillie was scared, and tried to touch Pikachu, but was unable to. Still, she promised to find a way to touch Pikachu. She took him to the playground and took some notes of him. The next day, Lillie gave a bowl of fruit to Pikachu. Recalling Pikachu's bond with Ash, Lillie felt the best way to bond with him was by having a battle. Lillie had Pikachu battle Hobbes' Oricorio, but Pikachu was overwhelmed by Oricorio's attacks. Lillie snapped out of her moment, seeing if she thought about losing, she wouldn't be able to touch Pikachu. Lillie asked Pikachu if he trusted her, and Pikachu confirmed this. With Quick Attack and Thunderbolt, Pikachu defeated Oricorio. Lillie was thrilled and hugged Pikachu; when she realized that she was touching him, she did not mind, instead commenting on how warm he was. The next day, Lillie showed to everyone she could touch Pikachu. Ash was amazed and challenged Lillie to a battle, to show how much he and Snowy were training. Lillie accepted, and she and Pikachu fought Ash and Snowy. Olivia visited the Pokémon School and met the heroes, and their Pokémon. With everyone ready, Olivia led the class to a boat, which sailed off to Akala Island. As they sailed off, they found a Wailmer being attacked by the Bruxish. Once Bruxish was defeated, Lillie watched as others dived in to rescue Wailmer, and succeeded. At evening, the class arrived to Akala Island. For their course, the class chose a Stoutland as partner; Lillie even dressed herself accordingly for that. Later, the class went off to find treasure with the Stoutland they chose. Due to her fears of touching most Pokémon, she was unable to ride Stoutland. Kukui and Olivia encouraged Lillie to continue on and try. Lillie, who remembered her bonding with Pikachu and Snowy, continued on. As Olivia was evaluating the items the class had found, she and Kukui showed that Lillie was able to mount on Stoutland. In the end, Lana and Lillie were both pleased with the progress they made that day. Lillie went with her friends, except Ash and Lana, to Kiawe's farm. There, Lillie gave Snowy some food and Moo Moo Milk, ignoring Kiawe's pleas to help him with the chores. She was impressed by the milk, as Snowy immediately ate the food dipped in the milk. Returning to the Pokémon Center, Lillie was amazed that Lana had a Z-Ring and a Z-Crystal, and was not amused by her joke that she caught a Mega Gyarados. Lillie and others attended Olivia's class. Olivia told them they had to cook, but Lillie was displeased since she could not cook. Regardless, she paired up with Kiawe to find the ingredients for the Akala curry. Later on, at the table, Lillie listened how Ash battled Totem Lurantis, and congratulated him for passing the Trial.Lillie watched the battle between Ash and Olivia, and was excited to see the Grand Trial in person. As the two had a Double Battle, Lillie wondered if Ash could attack with two of his Pokémon at the same time. Sophocles confirmed this, as a trainer has to show their power. She was also surprised at Rockruff's aggressive behavior, which resulted in Rowlet fainting. After Ash defeated Olivia, Lillie and others congratulated him for the victory. The next day, at morning, Lillie was surprised that Ash was missing. Ash and Pikachu returned, the former explained Rockruff went missing, making everyone search for it. The next day, Lillie and others admired Ash's Lycanroc in Dusk Form, as they sailed back to Melemele Island. Lillie was at school when Mallow went to her cafeteria, to prepare herself for the TV presentation. Later, she went with his friends to the cafeteria, and was shocked to hear from Abe that Mallow ran away. Lana believed Mallow went to the forest, and Lillie confirmed this, since Mallow usually went there to gather ingredients. The group went to search for Mallow, and tumbled down a hill, finding her at Oranguru's hut. Lillie watched as Mallow hugged her father, who complimented her on all the work she did recently. While at school, Lillie along with Mallow and Lana were complaining about the heat until they realized it was the boys being all fired up, who were getting excited for the upcoming Charjabug race their going to compete in, then were delighted when Snowy used her Powder Snow attack to cool them off. Lillie, Mallow and Lana were walking by until they saw the boys doing some training for the race then they decided to head over to Aina's Kitchen for some refreshments.
When the group went to the Kanto region for a special session, Lillie became concerned when Snowy became sick after the flight. Brock came and after a quick examination, told her that Snowy was suffering from motion sickness which would be dispersed soon. At Professor Oak's lab, she saw various Pokémon and was delighted when a Kantonian Ninetales befriended Snowy. She was also excited to see a Jigglypuff, though she fell asleep upon hearing it sing and had her face doodled on as a result. Lillie later battled Brock's Geodude with Sophocles and Togedemaru. She had Snowy use Powder Freeze on Geodude, who canceled it out with Gyro Ball. She is amazed by how knowledgeable the Gym Leaders are and later watches Kiawe battle Brock's Steelix while Ash battles Misty's Gyarados.
After Ash brought in a rare Pokémon to class, Lillie nicknamed named it Nebby. Upon her reunion with her mother Lusamine who is revealed as one of the members of Aether Foundation, Lillie finally shows her rebellious side when she became annoyed towards her mother due to her ditzy and doting behavior as well as her actions where she allows Clefairy to evolve into Clefable by touching the Moon Stone which Lillie claims the Clefairy is her very first Pokémon before Snowy causing both of them to have a fall out. When they went to the basement in Professor Kukui's house, Lillie confirms her support for Ash in taking care of Nebby to her mother as she tells her how strong he is, after she confirms that Nebby is an Ultra Beast. When Ash met up with Gladion, he revealed that Lillie acquired her fear of touching Pokémon due to an incident that occured when she was a child which was related to Nihilego and Silvally.
While at home, Lillie was talking to her mother on the phone when she found out that she requested Hobbes to record her whenever she was with Snowy then got upset with her for putting work before her family and hung up on her. When she went for a sleepover at Professor Kukui's house, Lillie felt guilty for getting upset with her mother before then learned from Professor Burnet that her mother really misses her and Gladion. Lillie expressed her desire to see Gladion with Nebby teleporting her to a cave where she saw her brother and his Type: Null. Seeing Type: Null's frightening eyes, Lillie remembered an incident then Nebby teleported them back to their friends. However, Lillie was not able to touch any Pokémon now, including Snowy.
Later at school, Lillie friends aporached her as they gave some encourgment then tried to touch Snowy but couldn't. After school was done, Lillie went for a walk with Ash, Rotom and their Pokémon friends accompany her. While walking, Lillie asked Ash if he saw her brother which he said yes to then was told on how her brother scolded him for Nebby's action. Although, Lillie laughed due to knowing her brother then tells her friends about how she remembered seeing Silvally as she believed it was one who attack back when she was little. After her friends cheered her up, Lillie decided to remember her past as she was inspired to finally conquer her fear of touching Pokémon and find out why she had that fear in the first place. Lillie and Ash got teleported by Nebby, who wanted to grant her wish, where she remember all the great times she had with her family along with all the fun she had playing with the Pokémon as well during her childhood. After being teleported to the basement of the Aether Foundation, Lillie remembered that something awful had happened to her here. However, Lillie was kidnapped by Faba and Ash tried to rescue her, but Faba's Alakazam and Hypno trapped them with Psychic. After Lusamine and Gladion arrived on the scene, Lillie watches her brother sent out his Type: Null to help her, which terrified her. Lillie witness Type: Null broke free of its mask and evolved into Silvally as it launched itself at the Alakazam so it would lose its Psychic grip on her. For a moment, Lillie was terrified but realises that Silvally was trying to save her and remember that it saved her when she was little. After Lusamine apologizes for her arrogances, Lillie accepts her mother's apology then tells her that she loves her then apologizes to Silvally for not realizing the truth sooner and for misjudging it. After thanking Silvally for saving her twice, Lillie releases that she let go of her fear for good then her three best Pokémon friends, Snowy, Pikachu and Nebby, came to her as she was filled with joy in touching Pokémon again. Lillie thanked Ash, who was very happy for her, for not giving up on her. While at school, Lillie shows her other friends that she was no longer afraid of touching Pokémon as she touched all her friends Pokémon in happiness. Lillie jumped roped with Snowy then they were both joined by their Pokémon friends, minus Nebby and Rowlet due to both of them being asleep. After finding out that Faba kidnapped Nebby, Lillie joined Ash and Gladion, who's been looking for Faba, to rescue her friend Nebby from him. Joined by her mother, Lillie sees Faba hurting Nebby when he was using it to power up Professor Burnet's machine but became relieved when Pikachu saved their friend from the box's that it was trapped in. When Nebby evolved into Cosmoem, Lillie witness the Ultra Wormhole opened which brought Nihilego, the Ultra Beast who attacked her, out from it. Seeing Nihileho again, Lillie became terrified but her mother comforted her. After it took her mother away through the Ultra Wormhole, Lillie becomes horrified. Even so, Lillie was willing to do anything to get her mother back.
After she and Gladion returned to the mansion, Lillie changes into new clothes and changes her hairstyle. Lillie was about to leave on her own but Gladion enters the room knowing that she intends to find their mother. Gladion tells Lillie that to open an Ultra Wormhole, you must go to the Altar of the Sunne on Poni Island, and that she should stay home while he goes to find Lusamine on his own, but Lillie insists on going with him anyways despite the danger. Gladion reluctantly agrees and they both runaway from home, riding on Silvally. The next day, they arrive at Vast Poni Canyon where they see statues of Rowlet, Litten, and Popplio in front of a door. Lillie thinks that it is a puzzle they must solve, by pushing the statues in place. But Gladion simply opens the door, then tells Silvally to push the statue Lillie is trying to push. Silvally pushes the statue in place, but it turns out to be a booby trap, unpleasantly surprising Lillie. Then they come across a cliff with a door on the other side of the ledge. Lillie thinks that there's an invisible bridge, but Gladion tells her to get on Silvally, and it jumps to the other side, revealing that there is no invisible bridge. Lillie wonders if she's slowing Gladion down. Gladion confirms this, but knows the Lillie won't go back even if he told her to. Then they arrive inside an old ruin that leads to the summit, but before they can get there, they are attacked by a group of Jangmo-o, Hakamo-o, and a Totem Kommo-o. Lillie sends out Snowy to battle the Jangmo-o and Hakamo-o while Gladion and Silvally deal with the Totem Kommo-o. Silvally's Crush Claw is proved to be useless against Kommo-os's hard scales, but Lillie gets the idea to use one of Silvally's Memory Disc to change it into a Fairy-Type Pokémon. However, one of the Jangmo-o knocks the disc out of Gladion's hand, and lands right underneath the Totem Kommo-o. Thankfully, Snowy uses Powder Snow to freeze the ground and keep the Jangmo-o and Hakamo-o at bay, while Gladion and Silvally slide on the ice a grabs the Memory Disc, and changes Silvally into a Fairy-Type Pokémon before Kommo-o's Clanging Scales attack can hit them. Silvally defeats Kommo-o with Multi Attack, then Gladion praises Lillie for her idea. However, the ruins start to collapse. Lillie, Gladion, and Snowy ride on Silvally and barely avoid getting crushed by a falling boulder, thanks to Pikachu. They make it out unharmed, quickly followed by Ash, Kiawe, Lana, Mallow, Professor Kukui and Sophocles, who have followed them to Poni Island to help them save their mother. Though Gladion tells them that it's a family matter, Lillie and Ash convince him to let everyone help and trust them, which Gladion reluctantly agrees. Then everyone arrives at the summit, where Tapu Koko, Tapu Lele, Tapu Bulu, and Tapu Fini are waiting for them. Upon reaching the Alter of the Sunne's summit, Lillie and her friends met the Tapu Guardians where she asked them if they could use Solgaleo's power in their quest to rescue her mother, Lusamine. By combining their terrain moves they showed the gang Nebby's origins and through the Tapu Guardians powers Lillie and her friends witnessed Nebby evolve into the legendary Solgaleo. With Nebby's help they were to open an Ultra Wormhole heading off into the Ultra Beasts world, leaving Professor Kukui and Professor Burnet, who also wanted to help rescue Lusamine, behind.
By the time Lillie, Gladion, Ash and the group found their mother Lusamine who is now fused with Nihilego at its dimension, she sends six of her Pokémon to fight them. Lillie is mostly protected by Snowy and Ash's Lycanroc while facing off against Clefable who is under Nihilego control and attempts to attack them with its powerful abilities. Lillie also carries her Clefairy doll to help Clefable remember the good times they play together during her childhood. When Clefable attempts to attack her with Dazzling Gleam as Lillie hugs it, Clefable was finally freed Nihilego control and it finally recognizes her.
Lillie was alongside Gladion, Ash's Lycanroc and a recently freed Clefable as they reunite with Ash, Pikachu and Nebby during the confrontation against Nihilego who was still fused with their mother Lusamine while they were mounted by Gladion's Silvally. She was carried by Clefable by hopping using its Magic Guard ability and was followed by Gladion who manages to install his Silvally using Steel Memory. Lillie was the only one can reason with her mother as she climbed the rocks that she lifted and dislikes her attitude as well as her corruption. She convinces her mother Lusamine to return to them which she recognizes her love for her children. As Lusamine tries to take her daughter's hand, she was ensnared by Nihilego and engulfs her with its black ink and rocks as it attacks Lillie, but Gladion saves her. After Ash defeats Nihilego using a powerful Z-Move from his Pikachu, Lillie and Gladion tried to pull their mother out as she and Nihilego diffuses. Lillie tearfully hugs her mother after she apologizes to her children for not spending time with her family. She, along with her mother Lusamine, her brother, Gladion, and Ash and the group return to the Pokémon World while mounted on Nebby's back and reunite with both Professor Kukui and Professor Burnet.
While writing in her diary, Lillie tells about her adventure into the Ultra Beast world and how her, Gladion and their friends were all able to rescue their mother then she tells Snowy how excited she is in going back to the Pokémon school, due to taking some time off to be with her mother, so she can be with her friends. Lillie was greeted by everyone when she walked in as Pikachu goes to her shoulder then she thanks her friends for helping her and Gladion rescue their mother. The next day, Lillie was delighted when Ash tells her and the rest of their classmates that Professor Kukui and Professor Burnet were getting married. However, Lillie became disappointed when Ash tells her and everyone that the Professors aren't gonna do a wedding ceremony.

- Among Ash's companions, Lillie is currently the latest to get her first Pokémon.
- Lillie is the second female protagonist to change her outfit and hairstyle in the middle of a series; the first being Serena.
- However, unlike Serena, Lillie changed back to her original outfit and hairstyle.
- Lillie then switches again for her Ultra Guardians uniform, bringing the second hairstyle back.
- Lillie is Ash's only companion to be related to a rival.
- When Lillie, Mallow and Lana dressed up as Alolan Idols, they look like the heroines from the Pretty Cure franchise.
