He’s really beefy, has a down smash that is really good, has a lot of attacks that make him take half damage, (even side taunt!) He packs quite a punch, is the second most heavy in the game, making it harder to launch him, AND he has his crownerang that gives him super armor during the early frames, making it very useful for getting back on stage in my opinion.
But what do you think about King K Rool? Sure, I listed a bunch of great things about him, but he does come with some flaws, as being a heavy means getting stuck in combos a lot.
