Caleb Martin is a protagonist in the fanfiction series Yu-Gi-Oh! AP. He is the oldest of the "Gang", and as such is often revered as the wisest, the voice of reason, the "Jiminy Cricket", so to speak. Most notable, however, is his past with Alek: he was the one who originally taught Alek how to play Duel Monsters, and served as his mentor before he moved away. He constantly butts heads with Eddie, but most notable is his teamwork with Zach; the two are nearly unbeatable together as a team. During the first series, Duel Academy Adventures, Caleb played an Archfiend deck that formed around Pandemonium, Skull Archfiend of Lightning, and Imprisoned Queen Archfiend. Duirng the second series he has traded out the Archfiend deck for a Psychic one, built around Thought Ruler Archfiend and Hyper Psychic Blaster, as well as its upgraded form, Hyper Psychic Blaster/Assault Mode.
