Charles Ruttheimer III, more commonly known as Upchuck, is a student at Lawndale High. His creepiness and attraction to any female apparently runs in the family; his father wants a new swimsuit for his secretary, and his attractive cousins make the same growling noise he does. He is possibly the only male character who expresses any physical attraction to Daria, despite her consistent insults.

In the finale, Andrea finally relents and agrees to his advances, which pleasantly shocks him.
