Ox
The Ox is an American criminal who for much of his life was known for his significant size and strength, but whose mind is now in the small frame of the former Karl Stragg. He began as the muscle in the Big Man's Enforcers. After serving time in prison for the Enforcers' criminal dealings, Ox was parolled in late 1964 and was instantly coerced into being a lackey for Mister Fear along with the Eel. The three soon ran afoul of Daredevil, who brought them back into police custody in early 1965.[1]
The following year, Ox was manipulated by fellow inmate and scientist Dr. Karl Stragg into helping him escape in exchange for granting him exceptional intelligence. The plan worked, and the two escaped using the Ox's brute force. Ox led Stragg to the abandoned laboratory of his prior leader, Mister Fear, where Stragg carried out an experiment that switched their respective consciousnesses, leaving Stragg's mind in the Ox's body and vice versa. Stragg tricked the Ox, leaving him weak in mind and body while Karl became a brilliant powerhouse. However, side effects of the experiment soon became clear, as Stragg was filled with savage, brutish urges to rampage aimlessly across the city. He kidnapped Karen Page and returned to the hideout, only to be ironically outsmarted by the original Ox, who used a piece of heavy machinery to disorient Stragg and free Karen. The increasingly wild Stragg went to the police station heliport where he was confronted by the quickly released Daredevil once more. A fight ensued, and Stragg carelessly fell off the roof to his death. Given a new lease on life, the old Ox in Stragg's body intended to return to prison.[2]
