As a King K Rool main myself, his b-air is really something. Kills early, has an insane hitbox and is a great answer to a lot characters trying to recover. If you have a chance to go for it. Do it.
Respectfully, he doens't go by KirbyKid anymore. His current tag is Lukewarm and it'd be cool if you could refer to him as such in future videos if at all possible! I know it wasn't something announced so its understandable not having the update. Edit: Also, I see why using his old tag makes more sense in the vid since these clips are older.
Yeah I was about to say that he goes by KirbyKid in all these vids so it wouldn't make sense to say it's Lukewarm making K. Rool look god-like if all these clips still uses his KirbyKid tag
