Team Y-Radium, Y standing for your de-. They're probably one of the most dangerous teams, since Team Aqua and Team Galactic. They believe that poison Pokemon are the only ones that matter, and are gonna destroy the world, except poison pocket monsters... using a... giant nuke like pokemon. If your not in Team Y-Radium or a poison pokemon... ouch. They weird hose things they have in their backpack can shoot poison gas. They made the pokemon using radiactive stuff, and uh yeah. They like to use Koffin, Weezing, and Gastly. Toxini is a poison type gym leader.
Nintendo Press Space or Click The Y stands for... the pokemon they made.
