The School Principal is the principal of the elementary school where Christopher Thorndyke studies in the anime series Sonic X. He is a kind, caring man who is closely connected to the students of the school.
In his first appearance "Chaos Emerald Chaos", he announces that Chris' normal teacher, Mrs. Wendy will not be with them for the remainder of the semester and that Mister Stewart will be their substitute. He also appears in the episode "Techno-Teacher", where he is enjoying a cup of coffee until Mister Stewart barges into his office which caused him to throw his drink; the coffee flew and dropped on his head. Mister Stewart asks about E-51 Intelligente, in which the duo walked towards to see Intelligente. The principal notes that E-51 is a good teacher and says that Mister Stewart could learn from him before leaving.
