Roll Call: Valkyrie, Dr. Strange, Sub-Mariner, Hellcat, Daimon Hellstrom, Hulk, and Gargoyle.
Dr. Strange summoned an assortment of Defenders to the Sanctum Sanctorum to see if one of them might draw out Bruce Banner's mind within the Hulk, who Dr. Strange temporarily subdued with a spell of somnambulance (Marvel Fanfare #20).
As Dr. Strange stepped into his study, the evil wizard Xandu trapped Dr. Strange in another dimension and mystically prevented him from calling any of the Defenders to his aid. But all was not lost. With time in short supply, Dr. Strange created a magical portal to contact Thing.
Using the powerful Ruby of Domination, Xandu magically coerced Hulk into battling Thing. Unable to overpower the green goliath on his own, Thing instead destroyed the Ruby of Dominationthereby weakening Xandu and freeing Dr. Strange. The ordeal left Dr. Strange too fatigued to further pursue any magical means of bringing peace of mind to the Hulk (Marvel Fanfare #21).
