For the variant appearing in the games, see Tierno.

Tierno is a character appearing in Pokémon Adventures.


Tierno is a tall, heavy-set boy with black hair in a short back and sides that also resembles the leaves on Chespin's head. One of his most noticeable qualities is that he has a rather overweight physique. Even so, this hardly seems to impact his desire to be a dancer. He is shown wearing a large black T-shirt that has a Vanillite design on it, orange cargo shorts, a yellow backpack, and matching black and yellow sneakers. Tierno also wears a yellow watch with a black wristband.


Tierno is a friendly guy, who aspires to become a dancer. Tierno sometimes gets inspiration for his new dancing moves from his Pokémon, Corphish and sometimes uses his Roller Skates to improve himself. This also allows Tierno to develop certain strategies, both in battles and outside them.


X, who moved into Vaniville Town, saved Y's life and gave her advice. Y was charmed and introduced X to her friends, Tierno, Shauna and Trevor.[1]

Tierno watched X compete in the Junior Tournament. After X got depressed by the incident with the reporters after the tournament, Tierno took care of his Kanga.[2] Just as X won, a lot of reporters rushed to interview X and tried to push his friends aside.[3][4]

X & Y arc

Tierno and the gang, setting off on their adventure.

Tierno was watching Y try to persuade X to leave his house when Xerneas and Yveltal appeared in Vaniville Town in the middle of a battle.[2] Y quickly saved Tierno, Shauna and Trevor, but Tierno was horrified to see Vanville Town's dancing school be destroyed. After the legendary Pokémon left, he and the others set off to Aquacorde Town.[5]

Once there, they stayed at an inn. X refused to go in, instead staying in his tent on Y's Rhyhorn. Tierno came over to him and showed him the two remaining starters from Professor Sycamore. Tierno tried to get X out of the tent and become a Trainer again, as well as to apologize to Kanga for neglecting her all these years. X became infuriated with him, grabbing him by the collar. Tierno was unaffected, reminding X Tierno was the one taking care of Kanga all these years. When his anger dissipated, X let go of Tierno and disappeared back into his tent, refusing Chespin and Froakie. Tierno went back to the room he shared with Y, Shauna and Trevor. Unfortunately, the inn was actually run by Team Flare, and Tierno, Shauna, and Trevor were trapped inside.[6]

X's Chespin managed to fool Aliana's Diggersby into blowing a hole in the wall, Tierno, Shauna and Trevor were. Y's Froakie made a cushion of frubbles for them to jump out and land on. The five escape from Team Flare and decide not to trust any adult strangers.[7] The group stopped for a bit and watched as Y tried to befriend Eevee she caught earlier. They also watched as Y's Froakie battled Eevee and was affected by Baby-Doll Eyes, which made Froakie charmed and dealt no damage to Eevee, showing his affection towards her. Tierno and Trevor laughed at the attempt, seeing Froakie was trapped in love. Y also decided to nickname Eevee as "Veevee", a name Tierno found funny. After having a snack, the group went to a place, where trainers participated in games with their Pokémon.

Tierno thought Y should participate with Veevee, though she and Shauna disagreed, as they shouldn't force Veevee, for they should show some motivation, instead. Y participated in a "Head It" game she failed; Y was furious and started to yell, which made Tierno and Trevor wish she would stop being so rough on other people. Instead, Y put her Sky Trainer suit on and played "Berry Picker" game, where she had to feed her Pokémon with berries she harvested from the trees. Her friends noted how fast she was, since Y knew which berries her Eevee ate. Two Team Flare grunts appeared and had their Sliggoo attack Y, demanding X to give his Key Stone. X refused to help, which surprised Tierno, Shauna and Trevor. However, X pointed out Veevee evolved into a Sylveon and blew away the grunts and defeated Sliggoo. With the matter settled, the group continued towards Lumiose City.[8]

They arrived at Santalune City, where Tierno bought food and supplies for the group. Viola found them and invited them to her gym. Everyone but Shauna agreed, due to their rules, which Y was going against, and ran off.[9] At the gym, Tierno went through photos of Vanville Town's destruction with Trevor and Y. Later, Tierno and Trevor came across Shauna wielding a sword at Y and an unconscious Viola. Celosia explained that Shauna had been possessed. Tierno dodged Shauna swinging the Honedge and then fainted.[3] Just then, Korrina arrived with her Korrina's Lucario, whom she Mega Evolved. Korrina started skating around Celosia, a movement which Tierno appreciated as an aspiring dancer. After the crisis was over, Korrina gave Tierno a pair of Roller Skates, which could fit on any shoes.[10]

On the way to Lumiose City, Tierno was surprised X went out of the tent, only to Mega Evolve his Kangaskhan to defeat some Noibat, who nearly attacked them. Y reminded them that "walls had ears and dolls had eyes". Tierno and Trevor laughed at Y's mistold quote. X corrected her, stating "doors have eyes", which embarrassed annoyed Y that X spoke in these situations. A man approached the group, who invited them to a new facility. The man explained he wanted them to test out the facility for a kind of training, which Y recognized as Super Training. After Chespin took part in the Super Training, Tierno let Froakie join in as well. Two Team Flare grunts appeared and attacked them and Shauna tried to warn others, but Noibat's sound made everyone deaf. Instead, Shauna hit Tierno and Trevor, who were alerted at Team Flare's presence. The trio tried to command their Pokémon to attack, but failed. Once Y was saved and the Team Flare grunts were defeated, Tierno was glad he could hear everybody once more. The man, who took a video of X and his Pokémon training, wanted to use it for the promotional materials. The children were in shock, but X's Kanga smashed the video, ensuring nobody saw it. In the end, Tierno and his friends continued towards Lumiose City, trying to stay away from danger as much as possible.[8]

After the children arrived to Lumiose City, Sina and Dexio, seeing the children with Professor Sycamore's Charmander, believed the children stole the Pokémon. Sino and Dexia swooped down and took Charmander, but Tierno put on his Rolling Skates and caught up with Sino and Dexia, explaining what really happened. After the group arrived to the lab, Sycamore sent Tierno and his friends to a café, where Trevor's Holo Caster would be repaired, while X stayed to talk with Sycamore. They arrived to the café, where they met up with the Holo Caster's inventor, Lysandre.[11] Shauna and Tierno noticed how Trevor was getting tense and sweating. Lysandre wanted to look at Trevor's photos and sent his Gyarados, Mienfoo and Pyroar to surround the children. Fortunately, Trevor took Shauna and Tierno into the men's restroom when Diantha arrived and had a talk with Lysandre. After Lysandre left, the children had a talk with Diantha, who left. After exiting the café, they noticed Trevor passed out and had a fever.[12]

The group went to Prism Tower, where they found Alexa being attacked by the editor-in-chief. X tried to battle the editor's Pokémon, but Tierno noticed X's Pokémon's attacks were constantly countered. X's friends, along with Alexa, went out, where Alexa told them someone was covering the truth of the incident of Vaniville Town.[13] They tried to search for Professor Sycamore, but Tierno realized Sycamore must've already left, by using a different elevator out of the tower. After X defeated the editor and rescued Alexa's Helioptile, the group went out of Lumiose City.[14]

The group had some free time and Tierno used his Roller Skates to skate around the park, showing his moves. Since the group could only leave when X gave permission, Tierno continued to skate until that moment. After sliding down a rail, he was hit by a note from a woman with a Flygon, who was actually a Team Flare admin. Tierno read the note, finding out Team Flare wanted to infiltrate the Poké Ball Factory in Laverre City by sending a hijacked truck. Tierno demanded to know what was this about and the admin told him they wanted to cut the supply of Poké Balls from Kalos, thus taking from the weak and giving to the strong. Tierno went to warn others, but was hit by Flygon's Earth Power. X, who sensed something was wrong, came down and gave support to Tierno. Tierno had a strategy and had X use his Pokémon to attack the admin. The admin had Flygon retaliate with Earth Power. Just then, Tierno had Corphish grip onto Flygon's wings, causing it and the admin to fall into a bush. With this teamwork, Tierno and X high-fived each other. A moment later, Tierno continued to skate in the Skate Park, while Trevor started to wonder if this journey would make them all get closer to their goal, rather than just running away from Team Flare.[15]

After Y has done her Sky Trainer practice, she started taking her clothes off, making Tierno and Trevor embarrassed and look in an other direction. However, they heard Y screaming, for an Electrike went off with Y's clothes. X, Tierno and Trevor chased the Electrike, while Y's Froakie managed to fool Electrike by creating a frubble copy of itself. X suspected Electrike wanted to go up. After the Electrike evolved into a Manectric, the group was approached by Clemont, who offered help. The group watched as Clemont tried to search the tree for Manectric's Mega Stone, unaware a Team Flare grunt had taken it.[16] The Team Flare grunt had been detected and Clemont used the Aipom Arm to topple him down the tree. However, the grunt sent four Espurr, who started to attack, so Tierno sent Corphish to battle.[17] The group was helped by Cassius, whose Gourgeist restrained the Espurr. Tierno, Shauna and Y went to Cassius' house, where they met up with Tierno and X and met Emma, who lived in the house as well.[18]

Tierno and Shauna deciding that they should go to Team Flare's HQ.

Cassius took the children to the Battle Chateau, as a stop before Cyllage City. There, everyone boarded the helicopter, for Cassius explained a way to get into Cyllage City is through a cave, where they could've been ambushed by Team Flare troops. Just as they flew off, Cassius noticed 15 people approaching.[19] Tierno, Shauna and Trevor were startled, even more when Y, who was previously depressed, flew off in her Sky Trainer suit to battle things out. Eventually, Y defeated the leader, Yvette, while X had Elec defeat the Aegislash controlling the trainers, shocking Tierno, Shauna and Trevor the Aegislash can control so many people at once.[20] The helicopter started to malfunction, for the Sky Trainers have damaged the helicopter badly. This caused the propeller to rip Y's Sky Trainer suit, causing her to fall down, while the rest crashed into Cyllage City. X, Tierno, Shauna and Trevor left when Grant appeared and started intimidating Cassius for the damage he caused. As they were on the road, Tierno and Shauna confessed they talked with Y and decided they wanted to fight back against Team Flare, as they did not want to be pursued. Trevor was surprised, but X agreed to this request.[21]

The group found a trace of a battle, where Tierno noticed even the injured Sky Trainer, Yvette. Eventually, the group (aside Cassius) met up with Y, who explained what Team Flare was up to.[22] After discussing the plans, the children decided to make an ambush for Team Flare. After Celosia, Malva and Essentia arrived with the people to move the Xerneas tree, Tierno noticed his dancing instructor - the children realized these brainwashed people were from Vaniville Town. Y, noticing her mother among the crowd, flew to protect her and spoiled the ambush. The children went to attack, but Essentia had them all binded by her Trevenant. Fortunately, Diantha, Gurkinn and Korrina arrived to support the children.[23] Tierno, Shauna and Trevor, after seeing X managed to befriend Gengar Gurkinn gave to him, commended X for managing to Mega Evolve them. They also commended Gengar, Lasma, since it wanted some attention.[24] After X defeated Essentia, Tierno went after her, but Essentia activated her suit, transforming into Tierno himself. However, the function was unstable and Essentia went away. Trevor, Tierno and X went to support Korrina in her fight against Celosia, but Trevor found Korrina injured, with her Key Stone stolen.[25]

After arriving to Laverre City, Y, Tierno and Shauna started training with Gurkinn.[26] Gurkinn realized how odd it was that he trained a Sky Trainer, a Furfrou Stylist and even a dancer. Just then, Trevor arrived and reported X was gone and pointed at Clemont's glasses X obtained, which showed the three stones at Geosenge Town.[27] The group met up with the Gym Leaders - Olympia, Grant, Valerie, Ramos and Wulfric - then sailed towards Geosenge town on Wulfric's Avalugg. After seeing the Ultimate Weapon rising from Team Flare's headquarters, everyone started to push the "bud" from opening and activating.[28]

Olympia asked Tierno, Shauna and Trevor to go to the headquarters, through the incinerator room, to locate Xerneas and the main reactor. Tierno used his Roller Skates and grabbed Trevor and Shauna, then went to the incinerator's exit. Bryony noticed them and called her Bisharp back (who was battling Ramos' Gogoat). Bryony started to attack, but the children were pulled into the incinerator by Clemont, who was being thrown away there. After being told the leader of Team Flare was Lysandre, the group noticed Emma with a large man, called AZ. Tierno had Corphish smash the bars, setting AZ free. The group went to the chamber, where they found X defeated by Lysandre, who was standing on a platform. Trevor went to Lysandre and had his Flabébé blow away Lysandre. Clemont used the Aipom Arm to carry Shauna and Tierno to the platform, where they, along with Trevor, pulled the key to stop the activation of the Ultimate Weapon.[29] Tierno, along with Shauna, Trevor, X and Clemont were brought back to the field by Xerneas. After they woke up from unconsciousness, Y decided to be Xerneas' trainer. Y started giving commands and Tierno remembered Alexa gave them an article about Xerneas and Yveltal, which Y had memorized. After Malva appeared on Yveltal and was warned by Team Flare's scientists she couldn't defeat Xerneas (since Yveltal was tied in strength by Xerneas), Tierno, along with his friends and the Gym Leaders, held onto Xerneas, who fled the scene, carrying everyone away.[30]

Tierno, along with his friends, came to the Lost Hotel. There, everyone was eating the food Siebold had made. Later on, Tierno witnessed Y becoming a Mega Evolution Successor and congratulated her.[1] Tierno watched as Y caught an Absol. He thought it was strange an Absol would be at this area, since it is not the place for its habitats. Later on, he watched as X tried to catch Pinsir and was bewildered how he threw the Poké Ball. Still, he was pleased to see how Pinsir, who was still wild, managed to follow X's commands, in the battle against Blue and his Scizor.[31] After arriving to Anistar City, Tierno listened to Professor Sycamore's findings. Seeing X needed a Pinsirite and Y an Absolite, Tierno volunteered to find those Mega Stones. Shauna decided to join him, stating Tierno mustn't go alone. With X and Y's Mega Rings in their possession, Shauna and Tierno went away to track the Mega Stones.[32]

Tierno and Shauna, along with their Corphish and Skitty, went to find the Mega Stones, using the light of the Key Stone to guide them. Eventually, they collected a bunch of Mega Stones, from which one of them was the Absolite. Seeing the light in the distance, Tierno skated away, but started to fall down a cliff. Shauna tried to grab him, but failed and fell down as well. They stood up and were terrified to see a lot of Pokémon that were affected by the Ultimate Weapon, just like the Scyther they saw with Blue. Shauna started to cry and didn't want to help in search for the Pinsirite, which was underneath an Aggron. Tierno brushed her off, claiming these Pokémon were struggling to regain their life energy and they should also fight as well, else Team Flare would inflict a terrible fate on them all. Shauna saw his point and tried pulling up an Aggron with Tierno and their Pokémon to find the Mega Stone underneath it. Eventually, they returned to Anistar City and met up with Trevor and Y, the latter having her Key Stone returned and equipped Absol with the Mega Stone.[33] Trevor, Shauna and Tierno watched as X and Y fought against Essentia, who stole Y's Xerneas. They also saw that Zygarde appeared, whom Essentia's Trevenant binded with its roots. They also watched as Zygarde absorbed some green squishy things from the ground. After the battle was over, Tierno was grateful Y managed to retrieve Xerneas back. He was also shocked to hear that X saw a sleeping person inside Essentia's suit.[34]

Tierno set off with his friends, as well as Diantha and Blue, to the Pokémon Village. Tierno was glad that X actually suggested the plan to raid the Pokémon Village. On their path, Tierno was surprised that Croaky, who evolved into a Greninja, attacked them all with Water Shuriken. A moment later, Tierno and others fell asleep, due to Xerosic having emitted radio waves that hypnotized them all to sleep, using Malamar's power.[35] Tierno and others began waking up. They heard as X confronted Xerosic and told him his Charmeleon, once it would become a Charizard, could Mega Evolve. Tierno and others gasped, as they realized X was correct, for Charmeleon was holding onto a Mega Stone.[36] Blue woke up and showed his Charizard had a different-colored Mega Stone. Once Croaky emitted Smokescreen, Tierno and others tried to sneak by and go to the Pokémon Village. Instead, they were taken by the four scientists; Tierno faced Mable. Tierno claimed he wouldn't lose, as he and Corphish began the battle against her Houndoom. Mable, however, was annoyed that Tierno could move so fast on his Roller Skates.[37]

While facing Emma, X recalled his friends, including Tierno, who wanted X to come out of the house before their journey began. X told Emma that they both had friends they shouldn't betray.[38] Mable's Houndoom fired Inferno, which melted one of Tierno's Roller Skates and burned his leg. Mable claimed Tierno should surrender. However, Tierno refused to give up, and neither did his Corphish, who evolved into a Crawdaunt. Thus, the latter used Guillotine, defeating Mable and Houndoom. Tierno met up with Shauna and congratulated on her victory. After Trevor defeated Bryony, he was cornered by Aliana and her Pumpkaboo. However, Tierno, Shauna and the Pokémon surrounded Aliana, who gave up. The trio went to meet up with others, but faced Xerneas and Yveltal, who stood in place, with their colors drained; Xerneas was merging with Yveltal. After Team Flare's defeat, Tierno and his friends went in the van to Lumiose City. Surprised everyone was acting as if nothing happened, Tierno claimed they just protected their smiles. However, a couple claimed that these kids were the Lumiose gang and something should be done about it. AZ visited them and asked what was their goal.[39]

Tierno started to doubt whether fighting Team Flare was even worth in the end. AZ showed them the key to the Ultimate Weapon and sent his Golurk to attack, seeing that the people of Kalos were still ungrateful for the things they did. Tierno saved the couple from earlier, while AZ was convinced he'd be the same as Team Flare if he were to attack people. AZ saw their point and, after being reunited with Floette, went away. The group also refused Sycamore's offer for the party and went to Vaniville Town, where Y's mother was awaiting them. Three months later, Tierno formed a gang of dancers and visited Shauna and Trevor, who were working in Lumiose City, too.[40]
