An anthropomorphic talking pizza slice with sunglasses and a member of Uncle Grandpa's crew, Pizza Steve tells people how cool and awesome he is, which annoys his nemesis Mr. Gus. He is depicted as extremely vain. Despite this, he pretends to be very popular and a hit with women. He is a good friend of Uncle Grandpa. Pizza Steve is featured in his own cartoon shorts entitled "A Slice of Life with Pizza Steve", which usually involve Pizza Steve exaggerating his abilities. In "Tiger Trails", he claims to be a black belt in Italian Karate, but he wears the black belt over his eyes instead of around his waist. His catchphrase is "I'm like a modern-day Thomas Einstein except a brazillion times better!". His vainness is such a trait of his character that even King Julian is shocked by his vanity and actually wonders why Mr.Gus doesn't just eat Pizza Steve.
