Team Snagem
From the Pokémon Encyclopedia
Team Snagem are the main antagonists in Pokemon Colliseum. When you play the game, you will roam around the Ore region, and stop their evil plots. In the beggining of the game, your character is seen steeling a suit and a Snag Machine from Team Snagems' Base and detonating a bomb(this is where the story begins, as your character was once with Team Snagem, but left them out of discust).
