Clarissa's Metagross

Clarissa's Metagross is a shiny Pokémon obtained by her in Hoenn.

With Steven
Steven gave Clarissa Beldum when he was looking for a trainer to give it to. Though she was very hesitant at first (since Beldum only knew take down), Steven convinced her otherwise.

Sparks: Ruby and Sapphire
Beldum attempted to battle against Roxanne but due to Nosepass' Magnet Pull she was unable to recall it. Beldum ended up damaging Nosepass a little bit and it was finished off by Combusken's Double Kick. Later when Clarissa and her friends encountered Steven in Granite Cave, Beldum's trainer was kidnapped by a group of Sableye. Beldum evolved into Metang and learned Pursuit, saving Clarissa. Metang was used in Clarissa's battle with Norman and was the 2nd Pokémon she chose. It was evenly matched with his Vigoroth and lead to them knocking each other out. On Route 124 Metang and Clarissa were seperated from the group and were forced to fend of thieves that tried to steal from the Treasure House. In the process Metang evolved into Metagross.

Personality
Metagross is a very friendly Pokémon who acts like an older brother to Clarissa's Togepi.
