@Lobos_Del_Rayo: How about something like Samuel from Heroes where he gets a power boost from the number of supers around him but he is still powerful without the boost.
Yeah Scar would work great.
@Absolute_Justice: Lol. Been wondering if I need to depower SamJaz as well, but at the mo I reckon it's best to cap his power level for the time being.
So, limit the number of swords flying around your villain at a time, or give him a Chess addiction?
