Miles "Tails" Prower

Miles Prower, better known by his nickname Tails, is a character from the Sonic the Hedgehog video game franchise. He is Sonic's best friend and sidekick, and also an expert mechanic (though that aspect of his character is not shown much outside of the video games and comic books). He is able to use his two tails to propel himself into the air like a helicopter for a limited time.
