Lol. Mine would be Pikachu.
Oh noes, power is down! Pikachu, zap the t.v.!
Some kid comes up to me with a Raichu "haha n00b you use a Pikachu", then he takes it out with a Light Ball boosted SubPunch combo :P
Meowth wouldn't be bad, but I'm one of the rare people who likes Pikachu on here.
Drifblim wouldn't bad....Torterra would be cool coz you could have a moveable tree to sit under in the sun :P and if anybody disturbs you, hit them with a Leaf Storm or something...Wailord would be epic too. But no, Pikachu would be it.
