Chip

Chip is a small, mauve, brown-eyed flying dog who debuts in Sonic Unleashed. He has a shock of white hair on the top of his head, the same style that constitutes his tail, has tiny white wings on his back and a green bauble on his neck. He was first seen in a Japanese manga adaption of Sonic Unleashed. In this, Sonic wakes up after Dr. Eggman's mutation. Chip is flying around Sonic, acting as if they've been friends for a while. He appears to be constantly hungry, and appears to get on Sonic's nerves. He shares a similar personality to that of Marine.

Chip loses his memory when Sonic lands on him after he falls from Dr. Eggman's spaceship (making Sonic the first character to have no damage, i.e memory loss like Shadow after falling from space, but it might be that because he was a Werehog at the time he had enhanced durability) and follows Sonic on his adventure to help regain his memory. Chip loves eating and always carries chocolate around with him, always offering some to those he thinks needs it. Sonic even names him "Chip" for the chocolate chips on the ice cream he's eating at the time. He is optimistic and cheerful, but has a strange power he sometimes uses to help Sonic. He also has a dark secret hidden in his memories.

Personality
Chip loves chocolate, which he carries a lot of throughout the story. Also in the fact that he offers many people a chocolate bar when he meets them. He loves food a lot, as seen in one cutscene in Apotos; Sonic is trying to talk to him, but he was distracted by an ice cream stand. Chip is playful and slightly goofy, before a boss he will pretend that he is threatening and scary (a contrast to how he isn't, as seen in Night of the Werehog).
