Marine the Raccoon is a supporting character in the Sonic the Hedgehog franchise. She is a 20-year old anthropomorphic raccoon of Southern Island, and Sonic and Tails' first ally when they are transported into the home dimension of Blaze the Cat. She dreams to be a swashbuckling sea captain one day, and insists on treating Sonic, Tails, and even Blaze as her "crew" throughout the game.

"It's okay. I know what you're thinking. I don't have what it takes. I don't think I can do all this adventuring on my own. But I'm not going to give up. I need to keep trying harder and harder until I can do it!"
