Miles Prower (マイルス・パウアー Mairusu Pauā?), better known by his nickname, Tails (テイルス Teirusu?), is a fictional character from the Sonic the Hedgehog series. He is an anthropomorphic fox cub born exclusively with two twin-tails, hence his nickname. Because of his abnormality, Tails was the subject of bullying during his youth. One day, however, he met Sonic the Hedgehog and was inspired to become as cool as him after seeing him run like the wind. Tails soon after began following Sonic on his adventures and has since become his best friend and sidekick. He is able to use his twin-tails to fly by rotating them like helicopter rotors and is a mechanic genius and aerial pilot.

A gentle and sweet-natured soul, Tails was initially timid and lacked courage. After meeting Sonic, however, Tails has become more confident, eventually growing into a more outgoing, brave and independent individual, and a hero in his own right. Since encountering Sonic, Tails has looked up to him and stood by his side, helping him however he can during their adventures.

Voice: Tails' voice should sound like how it is in the games: Mid-high to high.
