Lester Dracula is Lily's younger brother and Grandpa's son.
According to Grandpa, Lester is a bum. Herman once loaned him $5000 for a scheme of Lester's, but he actually got his money back. Lily is also skeptical of him: "I haven't heard from him since the last time he went bankrupt." He is also described as a classy if not financially irresponsible werewolf.
