Grisor and Dr. Hakase are a mamodo-partner team who fought against Zatch, Kiyo, Shion, and Nya in the filler Magic Mirror arc of the Zatch Bell! anime. However, their spells are weak and based on Fire, but by adding the Mirror power, his spells get a hundred times stronger, like his weakest spell: Faigar. They, Nya and Shion Hibiki and Cut N' Paste and Kiichiro are characters who only appear in the anime.
