Powers: Baran is immeasurably strong and is partially invulnerable. He appears quicker than his considerable bulk would imply but lacks any developed skills as a hand-to-hand combatant.

Also, Baran appears to be emotional underdeveloped and has a very strong attachment to his sister. He can become uncontrollable if separated from Selinda.
