Iron Man

Tony Stark was a genius American engineer (he went to MIT at the age of 15) who was captured by the Vietnamese during the Vietnam war due to a booby trap. This booby trap caused shrapnel to enter his body and drew closer to his heart, threatening Stark's life. Wong-Chu, a Vietnamese commander, said that he would have Stark's life saved (and that he would free him) if Stark built a weapon of mass destruction for him. With the help of another physicist (Ho Yinsen), Tony Stark was able to construct a suit of armor, thus becoming Iron Man. They also built a magnetic chest plate that prevented the shrapnel from entering Stark's heart (although it requires continual use to allow Stark to survive). Iron Man escaped with the suit in the end. Because of Ho's death due to stalling the Vietnamese long enough for Stark to escape, Iron Man decides to take revenge. Throughout his comic book adventures, he fights against forces that threaten the USA and his company Stark Industries.

In M.U.G.E.N, Iron Man has been made numerous times by different creators such as Magus and Erradicator.

Erradicator's version


Despite being one of the earlier versions of Iron Man, it manages to be based off Marvel Super Heroes and Marvel vs. Capcom 2, but seems to be more akin to the former. It also boasts some superior tech in the form of a new Special, Hyper and a War Machine striker.

Unkoman's version


Is it a War Machine? No, it's an Iron Man! But considering how similar the two characters are, Unkoman didn't consider it too unjust to create the latter by spriteswapping the former. While it feels adequately enough like a different character, some rather minor, but noticeable thing were overlooked, even giving the impression of being a Sprite edit.

Magus's Version


Iron Man's gameplay has a good balance of close melee and long range attacks capable of dealing a good amount of damage. His A.I. makes great use of his close range attacks and rocket charge moves capable of suspending a player in the air and making brutal aerial attacks. Leaving very small gaps inbetween his assults Iron Man can K.O. quickly if not dealt with quickly. With almost all of his Hypers are high priority making him invulnerable when performing them. Iron Man has a large number of weapons in his arsenal making him an enjoyable character to play as, in addition to a second version to his armour when choosing palettes; 7-12 where his plasma shots are replaced by missiles and a flamethrower.
