My favourite?
Well, that would have to be the all-singing, all-dancing, all-bitch-slappin' Scizor, of course!
Not the mega though, I am disappointed that they made Scizor into a brick. He looks all sleek and awesome and then *poof* he's gone all stapler-hands on us.
When it comes to Megas its Absol all the way.
Or Swampert. So I herd u liek murder?
