Iron Man Suits
Powered armour, colloquially called Iron Man Suits, are a style of armoured flight-capable suits based on the Iron Man Armour designed by Tony Stark.
As well as Stark, numerous other people have created their own powered suits, including William Riva (on the orders of Obadiah Stane), Hammer Industries, Nate Richards, Riri Williams, and Toni Ho.
Suits are typically powered by Arc Reactor Technology, due to the very high energy consumption, and use Repulsors for flight and primary weapons systems.
