|“||If you're here to give Danville the best day ever, then I'm here to give Danville the worst day ever!||„|
|~ Khaka Peü Peü confronting the Beak.|
Khaka Peü Peü, or K.P. for short, is the main antagonist of the Phineas and Ferb episode "The Beak". He is a small-time supervillain bent on ruining the day of everyone he encounters, and the archenemy of Phineas Flynn and Ferb Fletcher/The Beak.
K.P. is a supervillain who has never had a good day in his life and has a strange quirk of ending most of his sentences with "thank you very much". He also has a wife who frequently complains about his evil schemes and throws chairs at him whenever he insults her. Upon hearing news of a superhero called the Beak, who is giving Danville the best day ever, K.P. plots to destroy him and give Danville the worst day ever. To that end, he creates a hovercraft called the Khaka Crawler out of old washing machines from his basement to wreak havoc in Danville, but his efforts are foiled by the Beak. Eventually in the end, the Beak reveals to be none other than Phineas and Ferb in a robotic suit, much to K.P.'s surprise. In the end of the episode, his wife shows up and throws another chair, forcing him to take her shopping for more "throwing chairs", much to his fury. Phineas and Ferb then decide to let it be, believing that K.P. is getting his punishment after all.
- K.P. is unaware as to why people laugh at his full name, which according to him translates from its native tongue as "the strong fist" or "that strong fist".
- K.P.'s nagging wife is voiced by Christine Taylor, who is Ben Stiller's wife in real life.
- His costume bears some similarity to the Riddler's, except with the colors reversed.
