Synopsis by Hal Erickson
In typical fashion, X-Men launched its fourth season with a multipart adventure. The title character of "Proteus" is a young mutant, actual name Kevin, who has the power to alter his surroundings. The son of mutant researcher Moira MacTaggart, Kevin has spent his entire life at the Muir Island Center. But upon discovering the whereabouts of his long-lost father, Kevin escapes from the island, determined not to let anything -- or anyone -- get in the way of his reunion with his dad. The X-Men try to assist in the search for the potentially dangerous Kevin/Proteus, but are held back by a sinister secret known only to Moira.
