King K

"Meet my peeps, Gonzales! I told you we were gonna square off, and now it's ON!"

- KP Pete

KP Pete, better known by his pseudonym of King K, is a KP Koopa who fights in the Minor League of the Glitz Pit in Paper Mario: The Thousand-Year Door. He leads the fighting group called the "KP Koopas", a.k.a. the "Shell Machines of Doom", and as such must be battled during Chapter 3.

History
King K introduces himself and the rest of the Minor League fighters to Mario after the latter's fight against the Goomba Bros.. Throughout Mario's stay in the Minor League, King K gives Mario advice and informs him of any recent occurrences, such as the Hot Dog Stand getting a new menu item or the "cutie at the watering hole". King K disappears from the locker room after Mario's fight with the Bob-omb Squad, having previously told Mario that he was thinking about retiring.

However, King K had actually had his energy drained by Grubba's power-draining machine, and Mario later finds him in an unresponsive state behind a block in the second floor of the Glitz Pit's storage room. The KP Koopas are replaced by the Wings of Night during the time King K is absent. KP Pete recovers after Macho Grubba's defeat, and can be fought again should the player choose to return to the Glitz Pit.

Tattle

 * (Outside the battle) That's King K, a fighter. His shell's yellow, but I think he's just a basic Koopa. He seems like a genuinely good guy, Mario. Plus, I dig the way he talks!

Trivia

 * The Paper Mario: The Thousand-Year Door website (now defunct) depicted what would appear to be King K (who simply states that his name is "K.P.") as a trash-talking red-shelled Koopa Troopa. It is possible that this was KP Pete's personality in a pre-release build of the game, or else may simply an error on the website's part.
 * KP Pete is not shown among those at Glitzville while Mario is fighting the Shadow Queen. However, his voice can be heard when the scene cuts back to the battle. Shellshock is present, though, and talks like King K, so it is likely that it was intended to be him, but the sprites were mixed up.
