Marine

This is Marine, Amy's clone. She was an early experiment of Gerald Robotnik (Eggman's really EVIL grandpa). He was studying the strange athromorphic creatures and got the prenatal DNA of Amy Rose. However, while he was using the DNA in the cloning process, the DNA mutated.

Marine was named and raised by Maria Robotnik. During testing as a todler, Gerald realized the child had super speed and strength. She was frequently called useless because she wouldn't help him obtain world dominance/destruction; she develops a shy, depressed attitude toward everything. The only time she ever gets angry is when someone threatens her firends or family (mainly Maria whenever she was still alive)
