What Happened To Every Version Of The Hulk?

One of the few Hulk forms not hosted by Bruce Banner, the Red Hulk was created when Thaddeus Ross - one of the Hulk's longtime enemies - optionally exposed himself to gamma radiation in order to try and finally beat the jolly green giant, having spent years dedicated to his demise.

Unfortunately for Ross, the Red Hulk is in many regards less powerful than the Hulk himself. Not only does he succumb to bladed objects much quicker than the Hulk, but he also lacks the ability to power himself up by getting angry that his green brethren does, meaning his strength level is far lower.

Ross' death at the hands of the Foreigner in Captain America (Vol. 9) #6 appeared to mark the end of the Red Hulk - although with the current Absolute Carnage event involving his skeleton, there's a chance he may not stay dead long.
