Rouge the Bat

Rouge the Bat is the treasure hunter and the anti-hero character from Sonic the Hedgehog series. She can find the pieces of the Master Emerald just like Knuckles the Echidna. Her rivals are Knuckles, Tails, Amy and Wave. Apparently, Rouge is a jewel thief, part-time government agent (working for G.U.N.), and self-proclaimed treasure hunter who plans to make all the gems and treasures of the world hers. Her current jewel obsessions are the Master Emerald and Chaos Emeralds.

In eight of the eleven games she has appeared in to date, Rouge wears a skintight black body suit with a large pink heart-shaped breast plate, long white gloves, and white thigh-high boots with pink hearts on the toes. Her boots have metal heels and soles. Whatever she stomps on would have some serious impact. She also has long eyelashes and wears blue (or pink in Sonic Heroes) eyeshadow. Despite her rivalry with Knuckles, she has a crush on him.

Trivia

 * Despite being an original Sonic Character, she is similar to the Spider-Man anti-hero: the Black Cat; because they both wear black suits (though the top half of Rouge's suit is the pink heart-shaped breast plate) with gloves & boots to match their Hair (Black Cat)/Fur (Rouge), both have an obsession for jewelry, & both having a secret crush with a red-colored heroic rival (Spider-Man for Black Cat; Knuckles for Rouge).
