Avengers: Covert / Instinct
Greer Nelson was the lab assistant of Dr. Joanne Tumolo, who was developing a process to enable a human being to attain his or her full physical and mental potential. Out of financial desperation, Dr. Tumolo had accepted private funding for the project from Malcom Donalbain, an eccentric former executive of the Brand Corporation, who planned to create an army of women warriors to serve him. Not trusting the test subject that Donalbain had coerced her to use, Tumolo had Nelson secretly undertake the experiment alongside the other woman. Donalbain’s test subject, Shirlee Bryant, and Greer Nelson emerged from the battery of treatments with superhuman physical capabilities.
