Tigra the were-cat started off as a short-lived 70s heroine known simply as "the Cat," before being reimagined into her current form. She joined the Avengers but did so alongside a daunting roster that included only her and the founding members. Feeling overwhelmed, she left and later found a better fit as a West Coast Avenger. Tigra's tenure was marked by ongoing issues reconciling her two souls. Her next major role was as a training instructor among both Avengers: The Initiative and Avengers Academy. She also gave birth to a son, William, genetically hers and Hank Pym's, but conceived with the Skrull infiltrator posing as Yellowjacket. Most recently, Greer reconnected with her old flame Moon Knight and assisted him with his Midnight Mission, even keeping the torch lit through his death and resurrection.
