When first introduced, Vellian Crowler is a tough teacher who believes the Obelisk Blue dorm is the best and hates weak Slifer Red students. He tries to get Jaden kicked out, but fails every single time. Eventually, he respects him and when he has a rematch with Jaden where he admits he doesn't want to see his students go.

I don't have a set voice for him, but please make him have a medium/high pitched voice.
