The anime should be up here, for sure. It's funny how none of the characters notice pokemon levels or stat changes (from calm mind for example), but in the special Pokemon Mystery Dungeon tie-in episodes, the whole thing is based on pokemon levels.
We all know the pickachu godmode thing, it's been that way since it beat Raichu in Gen 1.
Team Rocket is the only (from our view) sensical group of people in the anime. They always worry about food, money; are trying to get a quick buck, never intentionally commit acts of pure evil (Unlike Teams Magma or Galaxy) and in almost every pokemon movie (and some eps) help out Ash and his friends with no questions asked, even though Ash and his group would turn against them and hand them into the authorities first chance they get.
The MAIN thing that should be up there are the pokemon which fall under 'annoyer'/HM-Slave. (Zigzagoon, Sentret, Rattata and Bidoof)
