Catwoman
How do we define anti-hero? Because some of the names tossed around are villains turned heroes (Red Hood, Lobo, Catwoman) more recently. I would think Red Hood during the Lost Days was an anti-hero, but currently, just a hero who toes the line. Whereas Deathstroke and Lex Luthor would be villains who have hero-esque tendencies and more of a definition of an anti-hero, currently. Catwoman is an enigma all her own. Was she a villain or just a thief?
