Smash Legend
Because he is one of the best characters in the game. He's fast, a good gimper, only has 3 true bad matchups, etc.Marth, definitely.
I prefer Ike over Marth, I don't see why people consider Marth one of the best characters in the game.
Melee:there has never been a "bad" fire emblem character
even people who hate Ike say he shouldn't be lower on the tier list
