@Naix, I'll take a challange spot for your Colosseum. Take Power the Croconaw. Power truly believes that it is the most Pokémon in the world, and as such, may not evolve. That is, until he discovers the power behind learning Hydro Pump. That's right, Croconaw may finally evolve when it learns Hydro Pump at level 55. Good luck. Oh, and Croconaw/Feraligatr may NOT use moves other than STAB or Normal type because, you know, whatever. You need some sort of challange while using Croconaw.
