Lucas is the son of Flint and Hinawa, and the younger twin brother of Claus. He lives in Tazmily Village with his family and dog Boney. Lucas has blonde hair and blue eyes. He usually wears a red t-shirt with yellow stripes, blue shorts, white socks and red and yellow sneakers, although this outfit is temporarily modified when he is confused with the Masked Man (who he has a strong resemblance to). He realizes his PSI powers from Ionia, one of the seven Magypsies. To learn PSI, Lucas is forced to hold his head underwater for a period of time. Until he embarks on his adventure, Lucas has a reputation of being an emotional boy, even prior to the numerous crisises that changed his family.
World War X
Lucas appears in the Lapisverse for the first time in World War X, albeit this Lucas is in Nimbus. He attacks with PSI and the rope snake.
