Principal Graham is actually Vi's uncle. She never knew where he lived but usually got to see him on holidays. He actually is the one who invited Vi and the rest of the characters to the city in the first place. He is a man in his late 30s.

Physical Characteristics: He has a darker skin tone than Vi, a bald head, a well kept beard and mustache, brown eyes, and a muscular build.

Clothing: He is often seen in either a suit and tie or a simple button up shirt. Both outfits he wears black dress pants and brown dress shoes.

Personality: It's kinda hard to pin Principal Graham's personality down. He is often very energetic at school when he gives morning announcements in a radio show host voice and sometimes acts childish. One moment he could be acting like a well rounded adult and the next a hyperactive DJ. However he is also shrouded in mystery.
