Miles "Tails" Prower

Origin
Tails first appeared in the 8-bit version of Sonic the Hedgehog 2 for the Sega Master System and Sega Game Gear, in which Tails has been kidnapped by and must be rescued by Sonic.

He looks up to Sonic as a brother figure and has appeared in many games, including three of his own: Tails Adventure, an exploration-based platformer with RPG elements and a slow-paced style of gameplay compared to the majority of the Sonic franchise; Tails and the Music Maker, an edutainment game for the Sega Pico designed to teach young children about musical instruments; and Tails' Skypatrol, an originally Japan-exclusive auto-scrolling game with an original cast of characters.
