- This article pertains to the Robian version of Miles "Tails" Prower; if you are looking for information on the robotic Tails created by Dr. Ivo "Eggman" Robotnik, see Metal Tails. For the Zone Jail version of this character, see Mecha Tails (Zone Jail); for the Roboticized Master, see Tails Man.
Mecha Tails was the roboticized version of Tails. His only appearance was when the Bem abducted Sonic, Tails, Dr. Eggman and Snively. Both Sonic and Tails were roboticized into Mecha Sonic and Mecha Tails, while Eggman and Snively were deroboticized. The Bem used them as part of an experiment to determine if organics were better than robotics. Unsurprisingly, Mecha Sonic and Mecha Tails survived a large explosion, and Mecha Tails kept Snively pinned while Mecha Sonic defeated Eggman. Sonic and Tails were then deroboticized. (StH: #118)
- Mecha Tails is one of three "Mecha" versions of members of the Knothole Freedom Fighters, and like Mecha Knuckles is notable for not having been under Robotnik or Eggman's control.
- Mecha Tails appeared in an Off Panel during the Tails Adventure adaptation in Sonic Universe. Tails explained that the existence of this form made it inappropriate to give the name to T-Pup.
- Tails was later Roboticized again with Robot Master technology incorporated into his design, creating Tails Man.
