As a technology hero, your powers derive from technological mechanisms; either as Gadgets or somehow inherent. Possibilities include a powered suit, you being a robot, contol over some ultratech machinery or simply technologicaly sufficently advanced to be indistingusihable from magic.
You can choose Cyber, Guns, Items, Pulp, Sorcery, or Super as the type of schctick you pay normal cost for. If you pick Sorcery, it is not really supernatural, it just seems that way to the uninitated.
