Miles "Tails" Prower

Miles "Tails" Prower is Sonic's best friend and sidekick, he is one of the smartest characters in the Sonic franchise with an IQ that rivals that of the evil genius Dr. Eggman despite Tails being much younger: he is especially good at inventing and spends a lot of his time making new things.

Although officially named Miles he doesn't like being called that, he prefers to be addressed simply as Tails and this is the name almost everyone refers to him as in the series (though in one of the cartoons Sonic threatened to tell everyone Tails real name but didn't do so).

Tails is normally a sweet-natured young fox and although being born with two tails is fully accepted by those around him (then again Mobius is a world of blue hedgehogs, robots and chaos emeralds so a two-tailed fox isn't quite as odd as it may seem at first) - in fact these twin tails are a trademark of the fox and he can use them to gain limited flight much like a helicopter, a drawback to this however is he tires rather quickly - also unlike Sonic Tails is a capable swimmer and although not as fast as Sonic he has shown himself to be capable of running fairly fast if required and is also naturally agile.

Tails is very close to Sonic and sees him as his best friend, in many ways Sonic shares these feelings but doesn't always show it - which can cause irritation or sadness on Tails part, in general though the two get along well and when arguments do break out they are normally resolved without violence (though the famous duo have clashed once or twice due to differences of opinion).

Tails takes two distinct forms in both the comics and cartoons as well as the videogames - his usual yellow guise (which is used now) and the older brown guise (which was used in the early cartoons) - when in his yellow guise Tails seems slightly older and more intelligent while in his brown guise he is usually portrayed as younger and less intelligent (though he is always fairly smart regardless of his appearance).

Like Sonic with Amy and Sally, he is caught in a love triangle between Cream and Cosmo.
