His moveset was designed to be "stuff heavies don't usually do", but Sakurao forgot to make it cohesive to the point I'm convinced the armour gimmick was addrd later when they realized it was ****
Heh, his movest in itself is fine, it's just that some moves are too slow or too weak to be utilized properly, alongside some moves that don't match their animations, but this isn't a problem exclusif to K.Rool.
A little buff of speed here and some small change to his special there and K.Rool would be a pretty honest character. He wouldn't be amazing, for sure, but he be more balanced and fun overall.
Then again, this is the balance team that decide that, not Sakurai, so who know what will happen to him.
Here's an official line from the Sonic the Hedgehog trailer shown at Cinemacon. Enjoy.
Honestly depending on execution this could be good though. If anyone knows how to carry a movie (ironically enough), it's Jim Carrey.
Ohhhhh boy.
Can't wait to see more of this movie.
