Ash's Melmetal (Tom's Version)

Ash's Melmetal (Japanese: サトシミカルゲ Satoshi's Mikaruge ) is the ninteenth Pokémon that Ash Ketchum caught in the Alola region.

As a wild Pokémon
Meltan first appeared in SM111, where it and several other Meltan arrived on Melemele Island. While investigating the sewers, the Meltan were divided into two groups and one ended up at the Ultra Guardians base under the Pokémon School. After being chased out by Lusamine's Clefable, they encountered Ash and his classmates, who decided to study the newly discovered species. During their study, the Meltan scattered, save for a lone Meltan that decided to take a nap next to Ash's Rowlet. When Rowlet accidentally startled Meltan and caused its hex nut to fall off, Rowlet retrieved the nut before a wild Murkrow stole it. Taking a liking to Rowlet, Meltan chose to sneak inside of Ash's backpack, causing Ash to unknowingly take it home with him.

In the next episode, another incident with a Murkrow caused Meltan's hex nut to land in Team Rocket's van. After a failed attempt to replace the nut, Meltan and Rowlet encountered Team Rocket, who tried to capture them. When Meowth attacked, Rowlet defended Meltan by taking all of Meowth's attacks, leaving it unable to fight back. Rowlet's pain angered Meltan, who proceeded to defeat Team Rocket with a powerful Flash Cannon. Afterward, Ash arrived and brought Rowlet and Meltan back to the Pokémon School. Seeing how it bonded with Rowlet, Ash offered Meltan to join his team, which it accepted after saying goodbye to its Meltan friends.

Personality and Characteristics
Meltan is a naturally curious individual who is prone to wander off on its own. It formed a very close friendship with Ash's Rowlet after it protected it from Meowth's Fury Swipes. Also, Meltan looks up to Rowlet and sees it as a mentor figure, much like Ash's Noivern's relationship with Hawlucha. Meltan gets easily scared, as seen in SM111, where it was reluctant to follow its fellow Meltan into the sewer, only following when it was forced. Despite being scared, Meltan will help its friends in any way it can. After joining Ash's team, Meltan easily became close to Ash and became friends with its teammates. Meltan also becomes very upset whenever it loses its hex nut.

Like many of its species, Meltan consumes anything made of metal, as seen in SM112, when Professor Burnet discovered a frying pan partially eaten. Frying pans in particular appear to be Meltan's favorite food.
