History
Mary Carmody was the daughter of brilliant inventor William Carmody who had just developed a means of keeping the human brain alive after the death of the body. Shortly thereafter, Mary became the object of self-proclaimed Mongolian ruler Ulan Bator. Bator hired mobster Peg-Leg Martin to kidnap Mary, and when her father attempted to stop him, he was fatally shot. Turned into the Eternal Brain by his assistant Jim, William assisted Jim remotely in rescuing Mary. Following the death of Bator, Mary learned her father's fate and blamed Jim for his condition, hating him for it.[1]
While watching her father test out a prototype of what would eventually become Walkabout, Mary and Jim witnessed William being recruited by Jake Scott to help rescue his teammate Mister Justice.[2]Notes
- Mary's father William was later revealed to be a member of the Eternals posing as a human. It is currently unknown if Mary has inherited any sort of powers as a result.
