Metang first appeared as a Beldum in Less is Morrison where it went up against Ash's Pikachu in a battle. Even though Beldum can only use Take Down, the battle ended in a draw for both Pokémon. Later, Beldum was caught by Team Rocket along with Pikachu. Both Ash and Morrison used their Take Down techniques to break out of the cage Team Rocket put them in. They used the same techniques to rescue Beldum and Pikachu. Beldum defeated Team Rocket with a Take Down along with Pikachu's Quick Attack.
Metang and Morrison
In Saved by the Beldum, Beldum was sent out along with the rest of Morrison's team. During the preliminaries, it went up against a Trainer's Electabuzz. Beldum's major disadvantage was that it could only use Take Down, which was proven to be very tough for Morrison as Electabuzz kept blocking the attack with Protect and counterattacking with Thunder Punch. Just when it was about to be defeated, Beldum evolved into a Metang and used Confusion to stop Electabuzz's Thunder Punch from making contact with it. Metang then finished off Electabuzz with a Take Down, taking out the Thunderbolt Pokémon.
During the Ever Grande Conference, when Morrison wasn't battling, he would train Metang for their upcoming battles.
In A Judgment Brawl, after Ash defeated Katie, Metang defeated a Trainer's Machoke. When Morrison found out that he was paired up with Ash to battle each other in the second round, he trained his Metang by having it attack a tree. Morrison stopped it at the last second when he saw Ash as the tree. In the next episode, it went up against Glalie during Morrison's battle against Ash, after both sides had lost five of their Pokémon. Metang had some battle tactics such as stopping Glalie's Ice Beam with Confusion and redirecting it back. After a long battle, Metang was defeated by Glalie's spinning Headbutt.
Personality and characteristics
Metang is a very kind Pokémon, as shown when it saved Ash from falling off a tree of its own accord. It deeply cares for its Trainer and has a strong willpower, continuing to fight even when the odds are against it.
