Before Greer Nelson became the fairly-well-known Marvel character "Tigra", she starred as the superheroine "Cat" in the short-lived comic "Claws of the Cat", which lasted all of four issues, from 1972 to 1973.
In her third issue (cover-dated April 1973), she encounters the evil Kraken, and is knocked unconscious twice; first, in a boating accident, and later, she is shocked senseless by the villain.
I really loved the skintight yellow costume that she wore! I think that you guys will like it, as well.
