Ben Grimm was a member of the Fantastic Five, they went on many missions and even set up a hotline to help others. When the Fantastic Five were lured into a trap by Mephisto who phoned them while possessing Father Coen, Ben, Reed, Sue and Johnny were subjected to their worst fears. Johnny was unfortunately killed by Mephisto when the Surfer refused to sign Mephisto's contract. Ben was eventually freed, along with Reed and Sue, when the Surfer agreed to remain in Hades for eternity. With Mephisto's influence gone, Ben joined Reed and Sue years later at Franklin's graduation from college.
