## Origin as The Cat
In her 1972 debut, Greer Grant Nelson was a recently widowed woman who found work with Dr. Joanne Tumolo, a physics professor laboring to create a way to augment humans by scientific means.[1](https://www.marvel.com/amp/articles/comics/didja-know-the-history-of-tigra?linkId=58721926) Tumolo's project had a benefactor, the industrialist Malcolm Donalbain, who secretly wanted an "army of Amazons" to do his bidding; when Greer discovered his plans, she offered herself as a test subject, and the process left her with accelerated physical and mental prowess.[1](https://www.marvel.com/amp/articles/comics/didja-know-the-history-of-tigra?linkId=58721926) • [2](https://toonopedia.com/tigra.htm) She became the costumed crime fighter The Cat, wearing a suit designed in-story by Donalbain and fitted with mechanically enhanced hearing and night-vision lenses.[5](https://comicbooks.com/issue/the-cat-1-25626)
The series lasted only four bimonthly issues, plus one appearance in *Marvel Team-Up*, and the character then receded into uncertainty.[1](https://www.marvel.com/amp/articles/comics/didja-know-the-history-of-tigra?linkId=58721926) • [2](https://toonopedia.com/tigra.htm) The concept had originated with [Stan Lee](https://www.edgepedia.org/stan-lee) and editor Roy Thomas, who devised three female-led series for Marvel's 1972 lineup; *The Cat* was the first to debut.[5](https://comicbooks.com/issue/the-cat-1-25626)
## Becoming Tigra
In *Giant-Size Creatures* #1 (July 1974), Tony Isabella and artist Don Perlin gave the character a second origin.[2](https://toonopedia.com/tigra.htm) Dr. Tumolo, who had merely been hospitalized in the earlier story, was secretly a member of a species of Cat People who had co-existed with humans for many years. Greer teamed up with Jack Russell, Marvel's Werewolf by Night, to rescue Tumolo from the terrorist organization [Hydra](https://www.edgepedia.org/hydra-comics); in the process she took a fatal injury, and the Cat People used mystical means, an enchanted amulet and its "cat science", to transform her into one of their own.[2](https://toonopedia.com/tigra.htm) • [6](https://www.splicetoday.com/pop-culture/tigra-of-california) She gave up the power suit, which fell into the hands of the former teen star [Patsy Walker](https://www.edgepedia.org/patsy-walker), and emerged as a striped-furred were-woman with the keen animal instincts, agility, and unpredictable temperament of a wild animal without erasing her personality.[2](https://toonopedia.com/tigra.htm) • [6](https://www.splicetoday.com/pop-culture/tigra-of-california)
She could originally switch back to human form with a magic amulet, but later lost that ability and, as a side effect, grew a cat-like tail.[2](https://toonopedia.com/tigra.htm) *Giant-Size Creatures* itself lasted only one issue; more than a year passed before Tigra displaced Modred the Mystic as the star of *Marvel Chillers* in February 1976, billed as "Tigra the Were-Woman", a subtitle that disappeared when that series ended after five issues.[2](https://toonopedia.com/tigra.htm)
**One costume, two heroines.** The Cat suit Greer abandoned became the founding prop of another character: in *Avengers* #144 (February 1976), Patsy Walker found the original costume during an Avengers investigation of a Roxxon warehouse, tried it on, and began calling herself Hellcat.[1](https://www.marvel.com/amp/articles/comics/didja-know-the-history-of-tigra?linkId=58721926) The two later met and, as one Marvel feature puts it, compared notes on the best practices for feline furies.[1](https://www.marvel.com/amp/articles/comics/didja-know-the-history-of-tigra?linkId=58721926)
## The Avengers and the West Coast
Tigra became a member of the Avengers in issue #211 (September 1981) and moved in September 1984 to the newly formed West Coast branch, on which she stayed for years.[2](https://toonopedia.com/tigra.htm) A reading-order index likewise lists *The Cat* #1 (1972) as her first appearance and *Avengers Academy* #6 among her later appearances.[7](https://comicbookreadingorders.com/marvel/characters/tigra-reading-order/)
The [West Coast Avengers](https://www.edgepedia.org/west-coast-avengers) period produced her most sustained character work. A retrospective essay describes the 1985 series, with scripts by Steve Englehart and art by Joe Sinnott, Al Milgrom, and Kyle Baker, as a complex arc centered on the existential tug of war between Greer Nelson and her feral alter ego: after more than a decade living as Tigra, Greer felt her animalistic lack of delicacy was damaging her human relationships, and in *West Coast Avengers* #15 a metaphysical trial by fire led her to a merger of the two identities, "I'm Tigra, a STRONGER Tigra, faster, better, but my mind is clear! I'm still Greer Nelson inside".[6](https://www.splicetoday.com/pop-culture/tigra-of-california)
Later Avengers-related roles included *Avengers: The Initiative* (2007–2010) and *Avengers Academy* (2010–2012).[4](https://www.marvel.com/comics/characters/1009670/tigra_greer_nelson)
## Recent appearances
Tigra has been a recurring character in the recent [Moon Knight](https://www.edgepedia.org/moon-knight) line of comics, appearing in *Moon Knight* (2021) through issues #22–30, *Vengeance of the Moon Knight* (2024) #1–5, *Blood Hunt* (2024) #1–2, and *Moon Knight: Fist of Khonshu* (2024) #6.[4](https://www.marvel.com/comics/characters/1009670/tigra_greer_nelson)
A new chapter arrived with *[Civil War](https://www.edgepedia.org/civil-war-comics): Unmasked* (2026) #4, published August 5, 2026, written by Christos Gage with pencils by Edgar Salazar and cover by Geoff Shaw. Its tagline is "THE TWO FACES OF TIGRA!": a never-before-seen look at the truth behind Tigra's decision to spy for [Iron Man](https://www.edgepedia.org/iron-man), in which, in the wake of Goliath's death, she is assigned her first mission and discovers that lying for a greater good can cause far more harm.[8](https://www.marvel.com/comics/issue/132824/civil_war_unmasked_2026_4)
## Powers and abilities
Tigra's powers come from the Cat People transformation: superhuman strength, agility, claws, and heightened animal instincts and senses.[6](https://www.splicetoday.com/pop-culture/tigra-of-california) • [2](https://toonopedia.com/tigra.htm) Her claws are treated as edged weapons in Marvel's tabletop role-playing sourcebooks, inflicting Good edged damage, and she is described there as empathic, sensitive to the emotions of others.[9](https://mshgamer.com/wp-content/uploads/2013/03/TSR6900.Revised.Basic_.Campaign.Book_.pdf)
