Caleb is described as one of a pair of young buzz-cut military school twins. He answers to Lawson and seems to act like his bodyguard. Caleb is one of the Human Garde. Caleb presumably has a twin name Christian, who is later shown to be a clone.
- Duplication- Caleb can create copies of himself. He was assumed to have a twin called Christian, who was actually a duplicate of himself. Christian was shown to not be able to express emotions and seemed to be kind of empty. Christian is killed fighting a Piken-Mog and Caleb creates more clones to keep fighting.
- Telekinesis- Like all Garde, Caleb can move objects with his mind.
