Ray the Flying Squirrel is a Mobian flying squirrel and is a member of the Chaotix, and is best friends with Mighty the Armadillo. The two have teamed up with Sonic during an escape attempt, but Ray ended up being trapped when he grabbed the prison's Power Stone energy source and was caught in a Time Warp. Years later, Mighty found him and freed him, bringing him back to Angel Island. Ray joined the Chaotix and became a loyal, if timid, member, helping them face various foes on the island and then later on the surface as they fought Eggman alongside the Freedom Fighters.

Ray is not really the bravest person on the planet, but is extremely loyal and very courteous. Despite his fears, he is always willing to do what it takes to help his friends accomplish their goals, and as time goes on he becomes less timid and more eager to join the good fight. He often stutters when he speaks, but doesn't let it stop him from asking questions or do what he has been taught to do.

Ray's voice is completely up to your interpretation. He is oftentimes portrayed with a young teenager voice, like a young kid's middle-range voice, and he stutters A LOT. But you are more than welcome to put your own spin on it.
