and credits Thomas with coming up with the name. Tigra made her solo-feature debut with a 15-page story in the black-and-white horror-comics magazine Monsters Unleashed #10 (Feb. 1975), followed by a brief run in the umbrella series Marvel Chillers #3-7 (Feb.-Oct. 1976), and one more solo story in Marvel Premiere #42 (June 1978). Like The Claws of the Cat, Marvel Chillers was also cancelled due to struggling sales. Tigra went on to guest star throughout the Marvel line, often appearing in issues of the superhero-team comic The Avengers and later in the cast of the spin-off comic West Coast Avengers. She starred in the four-issue miniseries Tigra (May-Aug. 2002) by writer Christina Z. and artist Mike Deodato, and has since guest starred in She-Hulk, Civil War, various Avengers comics, and elsewhere. Tigra appeared as a supporting character in Avengers Academy from issue #1 (Aug. 2010) to its final issue, #39 (Jan. 2013).

Greer emerged from the regimen with greatly enhanced physical and mental capabilities, including the peculiar tendency to feel others' pain. Shirlee emerged with similar physical capacity but considerably less mental empowerment, a result they blamed on her lack of adherence to the preparatory regimen. Tumolo then investigated further, and discovered that Donalbain had created a mind-control device and a set of cat-themed gadgets, with which he intended to make Shirlee his mindless superhuman enforcer.

However, her intention to call the police was thwarted by a bombing
