It's still quite a accomplishment for Isaac to compete with Bandana Dee, the 4th star of Kirby and most logical Kirby inclusion for Smash though. With how many Kirby games there are, and how Golden Sun hasn't had a new game since forever, it's still great that Isaac has this much popularity. I recall Isaac not being less popular than even the likes of Little Mac and Roy last time. ChronoBound reminded me of this, but the last game's most popular characters where Mewtwo first of all, and then came Ridley, King K.Rool and Mega Man respectively. Isaac was a little lower, around the likes of Roy, Little Mac and Palutena. It's kind of a shame that out of all these characters, Isaac is the only one left out still.
