Smash Champion
But he's an iconic Nintendo character for most Nintendo fans, just like Tom Nook.
I kind of feel like his "iconic" status seems higher on SmashBoards than it actually is. I mean, yes, a lot of people remember the dog mocking them when they missed a shot. I also remember this irritation. What I don't really understand is how that warrants his inclusion as a playable character instead of something like an Assist Trophy.
