My favorite League of Legends champion: Kog'Maw! :D
Also, Cho'Gath Battlecast Prime is cute! I can't describe what it is. When you look at the picture below, it may look very boyish, but in game it just moves so funny, i love it. :) He somehow makes me think of my cat, who's walking or laying down with broad elbows, but inside he's just a little fella. ;)
Maybe I'm just a little crazy.
PS League of Legends is this game I've been playing for a year now, due to my bf playing this very frequently. Google it. ;)
