Khaka Peü Peü

 is a supervillain who terrorized Danville.

History
Khaka Peü Peü is a supervillain who has never had a good day in his life and plans to destroy The Beak, a mysterious superhero who is giving Danville the best day ever (and is in reality Phineas and Ferb in a robotic suit). He 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 wooden chairs at him. In the end of the episode, after the Beak reveals it's true identity, his wife shows up and finally ends up taking him away to "take her shopping for more throwing chairs."
