Mine is Roselia
Mine is Mew! It's just too cute and too awesome. I love the fact that it can learn every move. The shiny version is also pretty cool.
My favorite is Darkrai.
L. U. G. I. A.
Favorite combination of five unique letters. Picked it subconsciously a long time ago.
I've had other favorites, but none of them really sparked me and none of them have really got me attracted to them like a magnet to them. Of all the Pokemon fantasies I have, the super majority of the ones I have now involve me as a Lugia. And it's also the only Pokemon I would want a figure of.
Wartortle, as the name implies.
The lil' guy just looks so huggable. <3
