History
Not much is known about Ben Grimm's history, but at some point in time he became a member of the Fantastic Thors, alongside Reed Richards, Susan Storm and Johnny Storm, and the group eventually became part of the Thor Corps, a force composed of multiple men and women dedicated to enforcing God Emperor Doom's laws and preserving peace across Battleworld.
Along with the other members of the Fantastic Thors, Ben helped defend Battleworld's Shield during its final siege. However, they were ultimately unsuccessful in preventing the Shield from falling.[1]
