Tails the Fox was Sonic's best friend and a hero of Mobius. Helping Sonic stop Dr Eggman and other threats. He always was a engineer. Always making new tools, devices and such. He even made the Cyclone Mech. But sadly he never met his parents since he never seen them. But one day while working in his workshop. He stopped and saw someone...a fox who also had two tails like him.

Tails the Fox: "Who are you? Why do you have two tails like me? Most foxes have one tail. There's something familiar about you."
