Prince Hata  

Baka Ouji, ハタ皇子

Prince Hata is an alien prince who loves animals but they don't reciprocate that love. He has bitten off one of his pet's antennae and it grew back later. Despite this, he collects rare pets and often causes chaos in Edo with them because he is not good at managing them. Prince Hata is known as "Baka Ouji" (Stupid Prince) due to his simplicity and lack of responsibility. He appears frequently in the series and is followed by a Swiss-inspired theme song. His appearance resembles Majin Buu from Dragon Ball, with pink colors.
