 However, most of the advanced devices (such as powered armor and death rays) are too expensive for the common citizen, and are usually in the hands of government organizations like S.H.I.E.L.D., or powerful criminal organizations like A.I.M.. One major company producing these devices is Stark Industries, owned by Tony Stark (Iron Man), but there are others.Advanced technology has also been given to humans by hidden races, aliens, or time travelers like Kang the Conqueror, who is known to have influenced the robotics industry in the past.In superhumans, the energy required for their superpowers either comes from within using their own body as a source or, if the demand of energy exceeds what their body is capable to deliver, comes from another source.
