|“||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 a supervillain who appears in the Phineas and Ferb episode "The Beak" as the main antagonist and archenemy of The Beak (Phineas Flynn and Ferb Fletcher) through out the episode.
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.
