Miles "Tails" Prower (voiced by Bradley Pierce In Season 1 & 2 Brianne Siddall In Season 3) is an adorable young fox who is also Sonic's best friend. He prefers to be called "Tails" because he was born with two tails. Tails taught himself to fly by twirling his tails. He lived in Knothole with the rest of the Freedom Fighters. Tails didn't do much in the series, but Tails' best accomplishment was that he came up with a plan to fool Robotnik into believing that Sonic destroyed the power stone. Afterwards, Tails became an official Freedom Fighter.
- If the series was renewed for another season, Tails would have had a bigger role.
