20. Cyborg Tony Stark (Age Of Ultron #7)
In the Age of Ultron comic arc (which wasn't great as a whole, but had its moments), Wolverine's attack on the past version of Hank Pym completely changed the present that he returned to. When Wolverine returns to the present with Sue Storm, they find that the Savage Land is covered by a mass wreckage of crashed ships. Sue recognises them as being Kree ships and theorises that, in this new timeline, the Kree-Skrull War came to Earth. The pair then see men in armour calling themselves the "Starkguard" checking the area out. The two then go to New York City, with multiple S.H.I.E.L.D Helicarriers flying/hovering around. Their flying car is shot down as they find themselves attacked by the Defenders (consisting of a one-eyed Captain America, Doctor Strange, Hulk, Wolverine, Thing, a one-eyed Cyclops, Wasp in Captain Marvel's costume and Star-Lord). The Thing is surprised to see Susan "back" but the rest of the group believe the two are Skrulls. A fight breaks out with the Wolverine of this altered present going at it against the time-travelling Wolverine, with the time-travelling Wolverine putting down his double and saying they did what they had to do to make a better world. The Defenders realise they are not Skrulls and reluctantly realise they have to talk to "him." At that moment, the "him" is shockingly revealed as a half-cyborg, alternate reality version of Tony Stark (who has obviously suffered some serious injuries in this reality), who flies in with a platoon of armoured robots and is immediately revealed to be in charge. He obviously hasn't lost his trademark wit, in spite of his cyborg predicament, as he asks "who wants to tell their Uncle Tony exactly what's going on around here?"
