Ms. Fanservice: Tigra's typically clad in nothing more than a black bikini. Averted in that she's not trying to be sexy, it's just that wearing more conservative clothes is too warm for a person with a coat of fur.
My Instincts Are Showing: Tigra originally struggled to control her cat-like urges and desires. After her "Human" and "Cat" souls were fused, it ceased to be an issue.
Super Senses: Tigra has keen senses, much like a true cat. She also has a rarely used sixth sense that allows her to sense the emotions of others on a basic level.
Super Reflexes: Tigra has incredible reflexes. She was able to dodge Ragnarok's hammer after it was thrown at her, and showed incredible flexibility while training White Tiger and again when slipping out of restraints that would've easily held a normal person.
Super Speed: While not a speedster by any means, Tigra can move pretty fast if she wants to.
Super Strength: Though it's not usually played up, Tigra's officially as physically powerful as Spider-Man.
Super Toughness: Tigra's physiology makes her much tougher than an ordinary person.
