Roberta Mendez was the wife of Alchemax Operative One-Nine-Four-Zero, who forcefully subjected her to the Super-Soldier Serum. Under the code name Captain America, Roberta became the leader of Alchemax's Avengers alongside Iron Man, Hercules, Black Widow and Hawkeye. However, Roberta and Captain America were two different personalities existing inside her body, with Roberta unknowing of her counterpart. They briefly came into conflict with the Defenders, a superhero team not licensed by Alchemax, but they ultimately set their differences aside to battle against the Dweller in Darkness.
