Tails 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 became more confident about himself, eventually growing up to be 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. [Source: wikia]
