Re: If you could have a pokemon as a pet...
Mew: If Mew can transform into any Pokemon, know any move they do, and have any ability they have, Mew basically can do ANYTHING any other Pokemon can and top it just because it can do more. It ranks high on the cuteness scale, it's fun, it's kind, and-screw Smogon-It would probably be unbeatable in battles for the sheer fact that it's got that much up it's sleeve. I like anything Shiny, but it's cuter when it isn't.
Lati@s: Latios and Latias...I'd probably be at a brick wall here if I couldn't take both, folks. Both are kind, both aren't exactly easy take-downs, I'd never be late to anything ever again, and their last traits are what make me indecisive: Latias is cute and friendly, and Latios is cool and has a tint of bad*** to him.
Female Eevee: I like Eevelutions, and I think that if one isn't enough, then the other six I'd get from breeding this with a transformed Mew would be enough. Besides, Every last Pokemon relating to Eevee happens to be cute.
