He is the political and history teacher at Crystal Prep Academy. His classes were so boring that he was long ignored by the students. But one day, when he saved a bullied student, he defeated the bully with just one punch, and his popularity soared since then.
His classes became lively and bustling, but most students came to him to learn martial arts or to talk about their troubles, rather than to study the lessons, which made him feel disappointed. Even so, he pursued psychology to help everyone.
He was targeted by Principal Cinch for defending poor students who were bullied because of their family background, until Cadance became principal.
He has an extremely rare constitution that makes him completely impervious to magic. In his eyes, any abnormal phenomenon is automatically filtered as something that can be explained scientifically, so he does not believe in the existence of magic.
He took in a Frigibax that traveled from another world, but to him, it’s just a weird-looking big lizard.
