My poll vote is V-Nix, cause he contributes not only top notch characters, but he's always willing to help those who are unsure about how to do things... Me mostly..
as for my other votes, I choose MGSSJ2, for his character and stage contributions, but mostly for his entertaining demenor, he always finds a way to make you laugh. And that scores big points in my book.
my second vote is for Strider, though he doesnt contribute as much as the others, when he does contribute- its solid.
Plus I like how lazy he is, he reminds me of....me.
