10 Strongest Forms Of The Hulk
5. Old Man Hulk
In the first Old Man Logan storyline, it was revealed that Bruce Banner/Hulk had gone a bit batty when the bad guys took over the world. He decided the best thing to do was to get his cousin pregnant since she could 'handle' his seed, and he formed a gang.
The Hulk Gang was composed entirely of Hulk's children and grandchildren, but seeing as they were all a product of an incestuous relationship, they weren't ... all there. Most were mindless thugs and hillbillies named Bobbi-Jo, Rufus, Elrod, and the like, and their main job was to take protection money from residents like Wolverine.
Ultimately, Wolverine pops his claws and kills the Hulk Gang, which brought him to the doorstep of Old Man Hulk. In this timeline, Banner has grown to be as strong as the Hulk was originally, and when he transformed, he became a massive hulking monster — larger than any previous Hulk incarnation.
This Hulk was immensely powerful, and his strength made the 20th century Hulks look like children in comparison. Ultimately, his strength didn't help him in his fight with Wolverine. Old Man Logan let the Hulk eat him, and once inside, he tore his way out, killing Old Man Hulk in the process.
