Possesses Super Armor on many attacks: forward tilt, up smash, down smash, dash attack, and neutral aerial
Second heaviest character in the game, only behind Bowser, giving him high survivability
High launch power on many attacks
Possesses two meteor smashes: down aerial and back aerial
Has several moves that bury opponents in the ground, leaving them open to attack: down tilt, down throw
Has the best recovery of any Super Heavyweight and Heavyweight character, being able to recover from the edge of the stage all the way to the edge of a platform without any problems. His recovery can also send opponents upwards if the make direct contact with it, giving K. Rool the oppurtunity to fair to gain an advantage.
Tanking enemy attacks with Super Armor too often can break K. Rool's
K. Rool's armor health is indicated by cracks on K. Rool's belly. Over time, these cracks will repair themselves, as long as attacks that have Super Armor are not being used. If K. Rool's belly takes too much damage it will stun him, similarly to a shield break.
Some moves have significant start-up or endlag.
Super Armor does not resist grabs.
Projectiles are relatively slow: making them ineffective at long ranges.
Large hurtbox makes him easy to hit, susceptible to combos and juggling.
Rather slow on the ground and in the air.
Despite K. Rool's superb recovery, with enough precision, one is able to spike our crocodile friend and send him back where he came from.
King K. Rool is a Super Heavyweight character, with strong super armour on a lot of his moves. His side blunderbuss and crownmerang are projectile based, and has a very style-focused playstyle, with his meteor-smashing back air and down air, and his "K. Roolicide" where he sucks his opponent into his neutral special and launch them out to the blast zone (even though K. Rool can possibly still recover from it).
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.
This is reflected in K. Rool's trailer; where King Dedede (voiced by Masahiro Sakurai) trolls DK and Diddy (and the audience) with a fake reveal; only to be ambushed by the real K. Rool.
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.
King K. Rool is the second fighter in the series whose back-aerial meteor-smashes the opponent, with the first being Lucas.
