Ness is a possesed child that eats your soul with butter and jam. Why else would I main him!?
The Best Chercter is Sonic
then Luigi ^^
Does he do it fast O.o?
Anyway, jokes aside, Luigi is pretty fun to use. Also, welcome Luigi to the thread.
Edit: Put "fun use" instead of "fun to use."
Sonic is low tier, lulz. Low priority, very few KO moves, no projectiles, and a sweetspotless recovery... Sonic is just bad. He can only be used effectively with mindgames, and even then, it's a major risk.
... Weegee is either low or middle, can't remember. He's scary when you repeat his major fight strategy though; difficult to counter and even harder to predict. Once you understand a person's playstyle though, he's pretty easy to stop.
