Formerly a skilled athlete Greer "The Cat" Grant went on to marry a skilled albeit overprotective police officer. Her husband sadly died in the midst of a shoot-out, leaving her to raise their son on her own. She then received genetic enhancements involving fusing her DNA with that of a tiger. She has since then joined the Avengers to ensure her son is safe.
Tigra is extremely feisty, even before becoming who she is now. She is very loyal to her fellow Avengers although she isn't to privy towards water due to her cat genetics.
Superhuman physical abilities
Cat senses: Due to her tiger genetics, her sense of sight and hearing have been increased tenfold.
- This incarnation of Tigra shares elements with the comic version (her family life and appearance) but omits her mystical abilities and has her origin story fit more into that of Avengers: United They Stand.
