Tigra (Greer Grant Nelson) is a superheroine appearing in American comic books published by Marvel Comics. Created by writer-editor Roy Thomas and artist Wally Wood (Marie Severin was then brought in to help layout the art), with her early adventures written by Linda Fite, the character first appeared as the superpowered and gadget-wielding crime fighter the Cat in The Claws of the Cat #1 (November 1972). She mutated into the super powered tiger-woman Tigra in Giant-Size Creatures #1 (July 1974), by writer Tony Isabella and artist Don Perlin. Publication history The Cat was introduced in one of a trio of Marvel Comics aimed at a female audience, alongside Night Nurse and Shanna the She-Devil. Marvel writer-editor Roy Thomas recalled in 2007: The series lasted four issues, each with a different art team. Severin was teamed with acclaimed 1950s EC Comics artist Wally Wood as inker for the premiere, followed by Severin and inker Jim Mooney in issue #2; newcomer Paty Greer co-penciling with 1940s Golden Age of Comic Books legend Bill Everett, who also inked, in issue #3; and Jim Starlin and Alan Weiss co-penciling the finale, with Frank McLaughlin inking. A fifth issue of the series was drawn by Ramona Fradon, but the title was cancelled due to lack of sales on previous issues. Severin attributes the character's sensual appearance to Wood: "I remember saying, 'My God, I drew this woman and Wally inked her like she's wrapped in Saran Wrap.' His storytelling always had lovely inking, nice blacks and everything, but I didn't have her that revealing. The boys loved his work, though." The Cat appeared alongside Spider-Man in Marvel Team-Up #8 (April 1973) during her series' brief run. After a year's absence, she was revamped as the superpowered, part-animal Tigra in a two-part story in Giant-Size Creatures #1 (July 1974; "Giant-Size" refers to the comic's page-count, not giant creatures) and Werewolf by Night #20 (Aug. 1974). Writer Tony Isabella recounted "My memory may be a bit shaky here, but I recall the Giant-Size books were approved and put on the schedule without a lot of lead time...I think I got the assignment one day, pitched the idea on the next, and one day later was sitting down with Roy [Thomas] and Gil Kane to work out what Tigra would look like." He also names Don Perlin and John Romita, Sr. as having a hand in Tigra's appearance,
