Derek was seen in five comic strips but never appeared in any of the books. He met Nate through a chess summer camp. He thinks that he can beat Nate in chess, but is never able to. He also thinks of Nate as his idol. He even once asked Nate for his autograph which made Nate sort of smile. Derek loves to play chess, but is not very good.
Derek is shorter than Nate and wears a geeky "I Love Chess" t-shirt. He is quite chubby.
