History
This Hulk presumably shares the same history as his Earth-616 counterpart.
When Namor joined the Fantastic Four, his strength, coupled with the powers and might of the other members, led the team to many victories against foes that had previously been a thorn in the side of the team. One such foe was this version of the Hulk, who was easily trounced when the Thing and Namor fought him together.[1]
