If you want to stretch the powers of this character, perhaps the Gold Dust amplifies his/her protections, providing Resistant Defences, Damage Reduction, Damage Negation, obscure things like Flash, Power and Mental defence.
To really stretch things more, perhaps the characters "Super Power" only works vs other super powers. So if joe normal in the wrestling ring does a punch of 3d6 his powers don't kick in at all, but if Grond punches him with 25d6 his full defensive powers come into play.
