Iron Mario: Introducing Mario as Iron Mario (Mario Mario), Luigi as Rhodes (Luigi Rhodes), Peach as Pepper Potts (Peach Potts), Yoshi as Happy Hogan (Yappy Yoshi) and Donkey Kong as Iron Donker (Obadiah Kong)
Mario Mario, a Genius, Billionaire, Playboy, Philanthropist, who inherited Mario Industries from his father Howard Mario, is demonstrating missiles in Afghanistan with Lieutenant Colonel Luigi Rhodes, when he is wounded after the demonstration by one of his own missiles and wakes up in a cave imprisoned by the Subcon Rings, led by Wart. A doctor held captive as well builds an electromagnet to keep metal from reaching Mario's chest. They then builds a suit to escape. When he returns, he builds a better suit with a new reactor and a partner named M.E.T.A.L and helps people out. This makes his partner Obadiah Kong jealous of him, and he tries to build a new suit. He and his scientists can't make an Arc Reactor, so he steals Mario's new one, but Mario gets his old one back. Meanwhile, Mario's secretary Peach Potts and his dinosaur-human bodyguard Yappy Yoshi meet S.M.A.S.H agent Polygon Coulson to inform him of Kong's activities. Kong becomes the Iron Donker, and he fights with Mario. They reach the Mario Industries Building. Mario tells Peach to overload the reactor, which makes Kong fall into the building's reactor and die. Mario saves the day, gets the girl and soon reveal's he's Iron Mario. Later, S.M.A.S.H director Mick Hand tells Mario about the Smash Bros Initiative.
