Ash's Melmetal

This Meltan is a -type Mythical Pokémon owned by Ash and is the fifth Pokémon he obtained in the Alola region.

Personality
Initially, Meltan was prone to fear and it was not used to not following its fellow Meltan friends. However, Meltan can be a very brave Pokémon whenever its friends were endangered and can be very protective of them as shown when it believed that Ash along with Pikachu were gonna hurt it and Rowlet due to seeing the harm Team Rocket did before they showed up. Meltan and Rowlet quickly formed a close bond and friendship after meeting one another. Also, much like the relationship with Iris' Axew and Ash's Scraggy in Unova, as well as Ash's Hawlucha and Noivern in Kalos, Meltan admires Rowlet and views him as a big brother and a role model. As a result, Meltan instantly trusted and formed a closeness to Ash when Rowlet assured it that he's a very caring trainer towards all Pokémon. In addition, Meltan was able to become good friends with its other teammates, becoming more outward in general. Also, Meltan loves to eat metal, especially frying pans. Meltan has a tendency to act on its own without any input from its trainer. For instance, when Rowlet was in the middle of a battle with Ryuki's Pokémon, Meltan interrupted the battle by eating the metal decorations on Ryuki's suit. Later, while battling Ryuki's Druddigon, Meltan tried to use Flash Cannon when it failed to used Headbutt while ignoring Ash's commands in the process.

Biography
Meltan was originally sealed alongside its fellow Meltan within the crated located in underwater near Poni Island, until for some reason, the seal was broken and currently only three Meltan who are briefly seen walking underwater.

When Ash and his friends were finished with their studying at Poni Island for their preparation for the upcoming Alolan Pokémon tournament and return to Melemele Island, there were more than three Meltan aside itself who are sneaking on board, hiding in a shadow within the ship’s packaging room, eating few metalic substance and making ring sounds.

When they arrived on Melemele Island, Meltan and all of its friends were in a warehouse before they went into the sewer, after they ate the manhole cover. However, They ended up getting separated into two different groups when they were startled by a wild Rattata. Meltan and its group ended up in the Ultra Guardians base where they caused some trouble for Lusamine's Clefable, who was doing some cleaning, until they went upward and into the Pokémon School classroom. Seeing Sophocles toolbox, Meltan with its group ate the metal until they were discovered by Ash and his classmates when Lillie, who accidentally mistaken it for a bolt, picked up one of them. Meltan with its group were observed by Ash and his classmates along with Professor Kukui until they ran away, after they panicked from Kiawe's Marowak flame on his bone when he was doing a greeting dance for them. While its group were wondering around campus, Meltan came back to the classroom and saw Ash's Rowlet sleeping then it decided to take a nap next to him. Meltan woke up from its nap and freaked out by the way Rowlet, who woke up just before it did, was staring at it which caused it's hex nut to fall off. After Rowlet saved its hex nut from a wild Murkrow that was about to grab it, Meltan was very grateful for his help and followed its new friend into Ash's Backpack. Due to being inside Ash's backpack with Rowlet, Meltan was unknowingly brought to Professor Kukui's house by Ash while its friends were at the Ultra Guardians base with Clefable.

Meltan woke up from inside Ash's backpack then saw a frying pan to eat until Rowlet noticed it and grabbed it before Ash or his friends saw it then was put back inside Ash's backpack. While at the Pokémon School, Meltan kept giving Rowlet affection until another wild Murkrow grabbed it. However, Meltan was saved by Rowlet but its hex nut fell off and was found by Team Rocket. Meltan became sad to see its hex gone but Rowlet tried to replace it but saw that the hex nut means a lot to it and decided to help find it. They were able to find the hex nut when they came across Team Rocket, who wanted payback with it due to its other group of friends causing trouble for them when they ate their metal at their base when they became separated from each other. Meltan was almost attack by Meowth's Fury Swipes until Rowlet dove in to protect it and shield it from the Fury Swipes. Seeing Rowlet's determination to keep it safe from harms way and how badly hurt he was getting, Meltan decided to protect its friend and attack Team Rocket with its Flash Cannon attack. After Bewear and Stufful came to take Team Rocket back to their base, Meltan went to make sure Rowlet was alright then saw Ash and Pikachu, who been searching for Rowlet, arrived at their location. At first, Meltan believed that Ash and Pikachu were gonna hurt them until Rowlet assures it that their his friends, Trainer and teammate. Meltan was brought back to the Pokémon School where it reunites with its friends when Clefable brought them to show Ash and his classmates with Professor Kukui the hard work she did to get them to behave. Meltan wanted to be with its friends, at first, but decided to stay with Rowlet then it was asked by Ash, who saw their bond and friendship, if it wanted to join his team which it accepted as it already grew to trust him and knowing that it's gonna be with its friend as teammates. After Ash failed the first try to catch it when he accidentally threw the Poké Ball at its hex nut hole, Meltan was officially caught on the second try and became a new member of Ash's team.

Now an Ultra Guardian member, Meltan visits and greets its old fellow Meltan friends about their new jobs at the Ultra Guardians Base beneath Pokémon School under direction of Clefable, as they reply it to be great. Yesterday before meeting its old fellow Meltan friends again where Pheromosa's invasion started at night, Meltan was sleeping with Rowlet on the top of sofa, before being awakened alongside its fellow Pokémon teammates and Ash by Professor Kukui that Hala was under attack by the said Ultra Beast, but was too late when the Kahuna revealed the said Ultra Beast is after the Z-Crystals from their owners like him and the majorities of Ultra Guardians, and the Ultra Beast’s speed is unstoppable for them.

After Kukui's announcement for the first ever Alola Pokémon League, Meltan and the rest of the Pokémon were seen training near the beach.

After arriving with its friends at windy Malie City, Meltan wants to awake Rowlet, but Ash replies that he is always like this and still tired. Upon watching a passing by pack of Eevee, Meltan and Sandy begin to cause trouble, much to Lana’s charging. When Shaymin tries to get Mallow’s purchased bandanna that got flew away by a powerful wind, Meltan and Sandy follows and helps it. Though Team Rocket ambushes them afterwards, the only thing they forget to remember that Meltan can eat their metal cage trap, but both Meltan, Shaymin and Sandy are being ambushed while escaping, so both Sandy and Meltan fights the Team Rocket off while protecting Shaymin until Ash, Mallow and Lana arrived. While Shaymin heals Sandy who got hit by Sludge Bomb from James' Mareanie, Meltan uses a new move Headbutt, immune to Mareanie’s -type attack, with Sandy does the final blow before Stufful and Bewear drags Team Rocket away.

While visiting the Kantonian Gym at Malie City, Meltan got upset when it saw Rowlet losing against Ryuki and his -type Pokémon, Zwelious, as it went to eat some of the accessories on Ryuki's outfit in retaliation. However, Meltan ended up participating in a double battle with Rowlet where they faced Ryuki's other Dragon-Type Pokémon, Druddigon. During the battle, Meltan learned Harden and defeated Ryuki's Pokémon with a Brave Bird-Flash Cannon combination. After winning the match and went home to Melemele Island, Meltan unknowingly ate Ash's badge from Ryuki, much to Ash and Pikachu's dismay.

Meltan and its friends are summoned by Ash to assist Lana rescuing a Legendary Pokemon Kyogre from an illegal group of hunters. Meltan and Rowlet create a diversion, sending Meltan to eat the illegal hunters' Carvanha-like ship to make its system haywire without the hunters' notices. Once the diversion is complete, but Kyogre went berserk by blind rage, Meltan hop onto Rowlet in time and retreat with their friends to their respective Poke Balls.

Meltan was seen sleeping with with Rowlet in Ash's Backpack, it was later seen with its friends in a fantasy as part Professor Kukui's idea on how to use Z-Moves as a battle strategy.
