History
Due to unknown origins, Tony Stark died from a sort of brain aneurism, though many believed it to be from drinking a poisoned bottle planted by Obadiah Stane.[1]
This led to the Armor Wars lasting longer, and to Stane International, led by Ezekiel Stane, to rule the world.[1]Notes
The unknown origin of this Iron Man's death was due to the broken timestream caused by Wolverine,[2] possibly killing him by some form of brain aneurysm.
