Trivia
Despite being a Sonic character, She is based on Marvel's Anti-hero/Anti-villain: Black Cat from Spider-Man. Mainly because both have an obsession for jewels, both wear black suits (though Rouge wears a pink heart shaped breastplate), having white colored gloves and boots to match their hair (Black Cat)/Fur (Rouge), and both have a secret crush on a red colored hero (Spider-Man for Black Cat; Knuckles the Echidna for Rouge).
