Miles "Tails" Prower [Age: 8] Don't let his docile appearance deceive you. This cute twin-tailed fox is an absolute mecha-maniac with skills rivalling those of Dr. Eggman. Humble about his abilities, he always does his best to help out Sonic, who sees him as something of a cute kid brother. "Tails" can spin his tails like a rotor blade enabling him to fly.
