Miles Prower also known as "Tails" is a gentle-hearted, genius-level inventor and Sonic’s inseparable best friend and sidekick. Distinguished by his unique twin tails that allow him to fly like a helicopter, he serves as the mechanical brains of the team, piloting the Tornado and crafting high-tech gadgets to solve any crisis. While he started as a shy, timid fox following in Sonic's footsteps, he has evolved into a confident hero in his own right, proving that intelligence and courage are just as vital as speed.
