Tails

Miles Tails Prower is a two-tailed fox, inventor, and Sonic's closest partner in the Sonic series. He supports adventures against Eggman through engineering, piloting, and increasing independence as a hero in Sonic the Hedgehog.

Tails' place in Sonic the Hedgehog

Tails is intelligent, kind, cautious, and sometimes insecure when separated from Sonic's confidence. His twin tails let him fly, while his mechanical skill produces aircraft, scanners, weapons, and repairs.

Tails's defining traits and capabilities

Sonic's friendship helps him overcome bullying and fear, but Tails's strongest development occurs when he acts without waiting for rescue. Different continuities emphasize inventor, pilot, or field hero while retaining those core traits.
