Super Armor is indicated by cracks on K. Rool's belly. If K. Rool does nothing, these cracks will quickly repair itself. However if K. Rool's belly takes too much damage it will stun him, similarly to a shield break.
Projectiles are relatively slow: making them ineffective at long ranges.
Certain belly-based moves in King K. Rool's moveset grant armor. However, taking damage with these moves cracks his stomach armor, with K. Rool getting dazed upon it breaking completely after three armored hits. The armor regenerates when not using belly attacks.

Outside of minor cameos, Ultimate marks King K. Rool's first physical appearance in a decade, as he last appeared in 2008's Mario Super Sluggers.
King K. Rool is the third playable Smash Bros. character to have been created outside Japan, following Diddy Kong, also created as part of the Donkey Kong Country series by the British developer Rare, and Dark Samus, who was created by the Texas-based Retro Studios.
According to Masahiro Sakurai, King K. Rool's inclusion in Ultimate was a result of his popularity in the Super Smash Bros. Fighter Ballot.
In King K. Rool's trailer, King Dedede disguising himself as King K. Rool is similar to the Donkey Kong Country episode "Just Kidding", in which Diddy Kong and Candy Kong make Donkey Kong use a King K. Rool costume to pull a prank on Cranky on All Fool's Day, but backfire when they accidentally bring the real King K. Rool to Cranky's house and the Crystal Coconut.
