-Tied for #1 newcomer, worldwide, alongside Mewtwo.
-A DK rep, which would be fantastic. A great 3rd DK rep, and unlike the other prospect, not a clone of Diddy.
-"A bad guy." It matters a bit. If people can have their favorite battle of Mario vs Bowser, then they should be allowed to have DK vs K Rool.
-Amazing personality.
-Alternate costume fun galore
-Extremely easy moveset potential
To be honest, K. Rool is one of the, like, 3 characters I thin you can call a 100% "shoo-in." The only other ones are Mewtwo and I guess Little Mac. People who don't include K Rool, even if they aren't trying to, make rosters that should always be regarded as jokes.
