Sakaar has been destroyed by Galactus, and Caiera's shade has banished her son to Earth. After encountering the Fantastic Four, and a bombing by Noram Osborn of H.A.M.M.E.R. he's reverted to the body of a young child, with strange greenish skin and striking eyes. But he still seeks a reckoning with his father. But Skaar isn't without those who care on this strange new world. The Hulk's Warbound, who knew Caiera, search for him as Kate Waynesboro uses the Old Power bequeathed to her by Hiroim to track him.
