Vanilla is the mother of Cream the Rabbit, and plays more or less of a supporting role in few games. She was captured by Eggman in Sonic Advance 2, where she debuted, and eventually saved by her daughter and everyone's favorite blue hog. She doesn't get much screen time and is a bit generic, though she was never that important a character. In the Sonic X continuity, she has connections with The Chaotix, hiring them to find/keep an eye on Cream while she was out with Sonic & pals. It even went as far to show a possible love interest between her and Vector the Crocodile..... yikes.... what would their kids look like?
