Originally the apprentice of Master Sandada, the powerful wizard leading Banipal Witt's resistance against Princess Buburina, Doh Doh is also the brother of ChuChu. His fate changed upon encountering a cursed portrait of Princess Buburina. The portrait's magic instantly spellbound viewers into fanatical devotion, transforming Doh Doh from a cute-looking cat boy into an adult with a haggard appearance. This marked his shift from Sandada's apprentice to Buburina's servant.

As Buburina's henchman, Doh Doh carries out her orders but demonstrates limited competence, frequently failing to meet her expectations. Buburina shows zero respect for him, openly highlighting his ineptitude and reinforcing his role as an ineffective subordinate. His actions include assisting Buburina's schemes to dominate Banipal Witt, utilizing her magic and the giant dog Papadoll.

Doh Doh's allegiance to Buburina strains his relationship with his sister ChuChu, who actively opposes the princess and participates in efforts to thwart her plans, placing her in direct conflict with her brainwashed brother. Despite his diminished state, Doh Doh retains no notable resistance to the curse, remaining under Buburina's complete control throughout the film. The resolution leaves his fate and potential for redemption following Buburina's defeat unaddressed.
