In order to have a T1 martial character, the best model you can find is golden age Superman.

No, seriously. This is a character who, within his universe, can solve most problems with little to no outside help and has abilities which allow him to perform other characters jobs, sometimes better than even those who specialize in that area. Need a character who can deal immense amounts of damage? Boom. Disguise his face? Done that. Violate action economy? Done that.

This is even before you consider that he can create powers for himself on the fly, customizing his loadout to the situation. Basically, he's a T1 martial.
