Article on Super Mario Wiki King K. Rool

King K. Rool (キングクルール, King K. Rool) is the main antagonist of the original Donkey Kong Country series and several Donkey Kong spinoff titles and the archenemy of Donkey Kong and Diddy Kong. Unlike most Nintendo-owned antagonists, he was created by the UK-based developer Rare.

King K. Rool is the leader of the Kremling Krew, and King of the Kremlings. King K. Rool, like his spiritual predecessor Bowser, is a sinister, boisterous, overweight reptile who antagonizes Donkey Kong, much like how Bowser antagonizes Mario. However, while Bowser is a turtle-like chimeric monster who has frequently wavered between friend and foe for the Mario Bros. and is respectful towards his minions, K. Rool is an anthropomorphic crocodile, is consistently presented as a threat to the Kong family's safety and way of life, and mistreats and berates his minions.

K. Rool is the main antagonist of most games in the Donkey Kong series and the archenemy of Donkey Kong and Diddy Kong, making his debut in Donkey Kong Country as the final boss. In that game, he steals Donkey Kong and Diddy Kong's banana hoard for unknown reasons, but two official reasons given are either that he likes bananas, or he stole them in order to starve Donkey Kong and Diddy Kong and occupy their treehouse[1]. He made his return again in Donkey Kong Country 2: Diddy's Kong Quest as pirate captain "Kaptain K. Rool", where he kidnaps Donkey Kong and demands the Kongs' banana hoard for ransom, but Diddy Kong and Dixie Kong instead go to his home island, Crocodile Isle, to rescue him. Donkey Kong Country 3: Dixie Kong's Double Trouble! has him assume the alias of mad scientist "Baron K. Roolenstein", as well as kidnap both Donkey and Diddy to power his robot KAOS, in a bid to control the Northern Kremisphere; Dixie and her younger cousin Kiddy stop these plans and free Donkey and Diddy.

In Donkey Kong 64, he reappears in a new mechanical version of his old island, plotting to destroy DK Island with his Blast-O-Matic, but it gets damaged on arrival. He thus has Diddy, Lanky, Tiny, and Chunky captured, as well as Donkey and Diddy's banana hoard stolen again, to buy time to repair the weapon. Once the Kongs disable it, K. Rool flees, but crashes his airship on DK Island, where the final battle takes place: an extended boxing match where he goes by "King Krusha K. Rool" (with a typical champion boxer getup). He also appears in the Donkey Kong Land series, in similar roles to their SNES counterparts; he also appeared in DK: King of Swing and DK: Jungle Climber, as well as the spinoff racing game Donkey Kong Barrel Blast, which were developed by Paon. In the latter games his design is noticeably altered, as he no longer wears a piece of golden armor, leaving his tan belly completely exposed, and no longer has a tail; he also sports more realistic proportions, especially facial, and a brighter color palette. He did not appear in either game of the revived Donkey Kong series, developed by Retro Studios (Donkey Kong Country Returns and Donkey Kong Country: Tropical Freeze), and neither do his Kremlings, being replaced by the Tiki Tak Tribe and the Snowmads, respectively.

In Super Smash Bros. Melee[edit]

King K. Rool appears as a trophy.

King K. Rool
The demented head of the Kremlings and big boss in the Donkey Kong series. K. Rool is a giant, greedy glutton with a serious eye tic. While he fits the evil boss mold nicely, he's just enough of a bumbler to have gained a few fans over the years. His plan to blow up the DK Isles with his Blast-o-Matic shows how unbalanced he is.

In Super Smash Bros. Brawl[edit]

King K. Rool appears as both a trophy and a sticker.

The supreme commander of the Kremling Krew. King K. Rool steal bananas from Donkey Kong and ends up kidnapping Diddy Kong. He is so good at playing dead that sometimes the credits even roll as he lies there, feigning defeat. His brother[sic], Kaptain K. Rool, made an appearance in the game Donkey Kong Country 2: Diddy's Kong Quest.

King K. Rool is the basis for a paid downloadable content costume for Mii Brawlers, released as part of the third wave of costumes. The costume mixes elements from his older and newer designs.

North America Whereas Mario often squares off against Bowser, Donkey Kong must fight against King K. Rool. He's a big croc with a big attitude...and a tiny crown. He probably could have been Donkey Kong's most trustworthy animal friend. Think he'll ever have a change of heart? Not likely.
Europe This guy is to Donkey Kong what Bowser is to Mario. This crowned Kremling has a serious attitude problem. If only he could have been one of DK's Animal Friends instead... Maybe with just a little change of heart, he still could be! On second thoughts...nope. Never gonna happen.

In Super Smash Bros. Ultimate[edit]

As a playable character[edit]

Main article: King K. Rool (SSBU)
King K. Rool, as he appears in Super Smash Bros. Ultimate.

King K. Rool was announced as a playable fighter for the first time in an Ultimate-centric Nintendo Direct on August 8, 2018. King K. Rool is the first character in Link's Classic Mode character unlock sequence, and as such can potentially be the first character to be unlocked. His design is largely based on Paon's post-Donkey Kong 64 redesign of the character. However, his gold-plated belly and waist-long cape are based off his appearance in the original Donkey Kong Country. His more pronounced scales are original to the Smash Bros. series. During certain attacks, he dons outfits as references to several games, such as his "Kaptain K. Rool" pirate hat from Donkey Kong Country 2: Diddy's Kong Quest during Blunderbuss, and "Baron K. Roolenstein"'s Propellerpack from Donkey Kong Country 3: Dixie Kong's Double Trouble!.

King K. Rool’s inclusion was largely facilitated by popular demand within and outside of the Super Smash Bros. Fighter Ballot. In an interview following the August 2018 Smash Direct, Masahiro Sakurai revealed that the development team used the survey as reference for choosing newcomers and that King K. Rool was a massively popular choice in the poll. He said that it would be better if he left the moveset to the player’s imagination at the time of his reveal, but specified that to maintain his likeness that he would be standing upright, even if he will appear smaller than usual.[2]

As a costume[edit]

King K. Rool's costume for the Mii Brawler from the previous game returns, now being an unlockable costume. In contrast to K. Rool as a playable character, the costume retains its more old-school proportions and design quirks, although its textures were also updated to match the ones of the playable K. Rool.



  • While King K. Rool has had a voice actor in his own series, with his current voice actor being Toshihide Tsuchiya, Super Smash Bros. Ultimate does not give King K. Rool a voice actor, instead giving him realistic crocodile grunts, similar to his appearances in some Donkey Kong games such as DK: King of Swing for the Game Boy Advance. The same thing happens to Donkey Kong, who is given realistic gorilla grunts rather than using Takashi Nagasako's voice clips from other games; Diddy Kong, who uses realistic chimpanzee screeches instead of using voice clips from his current voice actor Katsumi Suzuki; Bowser, who uses realistic roars instead of his current voice actor in the Mario games, Kenny James; and Petey Piranha, who uses monstrous roars instead of his current voice actor in the Mario games, Toru Minegishi.
  • King K. Rool is the only Donkey Kong fighter to have made a non-playable appearance in the series prior to his debut as a fighter, as he appeared as a trophy in Melee, a trophy and sticker in Brawl, and a trophy and a downloadable Mii costume in both versions of Smash 4.
  • Although King K. Rool's name is the same between Japanese and English, the announcer pronounces it differently between regions: the English version pronounces it as "King Kay Rool", while the Japanese version pronounces it "King Cruel", which is the basis of the pun on which his name is built.
  • King K. Rool is the only playable Donkey Kong character whose onscreen appearance does not involve him jumping out of a DK Barrel.
  • King K. Rool is the third character in the Super Smash Bros. series to be created outside Japan and the second character to originate from Europe.
  • Sub-universes applied, King K. Rool is one of the four Mario fighters not to have amiibos based on them in the Super Mario amiibo lineup, the others being Piranha Plant, Bowser Jr. and Dr. Mario.
  • While most characters in the Japanese version omit honorifics and titles (such as King or Princess) from their names, as well as surnames (such as Aran, Belmont or Bogard), K. Rool is an exception, as he keeps the title of King in his name. In the English version he shares this peculiarity with King Dedede.
  • Humorously, King K. Rool's trophy description in Super Smash Bros. 4 states that he could have been a friend to Donkey Kong with a "change of heart", but deems the event not likely. Perhaps coincidentially, during Joker's gameplay reveal trailer, he gets his crown stolen by Joker (who in his home series changes the heart of people by stealing their treasure) and is afterwards seen sleeping in the Kongs' treehouse during Banjo & Kazooie's reveal trailer.
  • Out of all the Mario sub-fighters physically, King K. Rool appeared in the least amount of Mario games as his only appearance was in Super Mario Sluggers.
