Tails

Miles made his first hit in Sonic 2[?] where he played the part of Sonic's sidekick and also as a playable charecter. Unfortunately, he could not be made to fly at this point- but this changed in Sonic 3[?] when he made his second major appearence. This was a big step forward for Miles and he got much more well known and respected at this point.

In more recent games in the Sonic the Hedgehog series, Tails has prefered to use a mechanic device to attack rather then his own strength, an arguably much more effective method. The fact that he made these mecha's (and the way that he speaks) proves that he has dramatically improved in intelligence, surpassing all of his friends. Boy genious Tails can now been seen in action in Sonic X[?], a TV series in Japan- in all his brainy glory.

Recently (or not so recently, just more popular now) alligations of a Tails-Amy relationship have appeared. This may be scraped upon by the TV series, or it may simply never be expanded upon.

The Tails character is perhaps based on the legendary kitsune.
