The description clearly matches Iron Man (Tony Stark). He was created by Stan Lee and Larry Lieber, is an industrialist genius engineer who uses powered armor from Stark Industries, and his enemies include Ironmonger, Titanium Man, and Crimson Dynamo. The other options are DC Comics characters (Superman, Batman) or another Marvel hero (Spiderman) who don't fit this description.
