S1E22 Hatenko the Hunk Has the Key to Your Heart

Title: Hatenko the Hunk Holds the Key to Your Heart Plot: Hatenko, a once-esteemed ally of Bo-bobo from the Hair Kingdom, confronts him to voice his discontent with Bo-bobo's current situation and thwart anyone who stands in his way. However, the tables turn when his deep infatuation with his "great sun," Don Patch, comes to light. To complicate things further, Kitty-Poo, the second member of the Baldy-Bald Big Four, arrives to avenge Battleship and poke fun at a classic shōnen anime. But Kitty-Poo makes a critical mistake: he underestimates Don Patch, who takes him and his companions down with a single blow!
