Miles "Tails" Prower

Tails is a two-tailed fox who is in search for Sonic. His full name is Miles "Tails" Prower. Tails is voiced by Colleen O'Shaughnessey.

Storyline (Spoilers):

The the post-credit scene of the movie, It shows a cliff. And a mysterious ring portal shows up on top of it. A figure jumps through the portal and landed on top of the cliff and the figure revealed itself being Miles "Tails" Prower (aka Tails). Tails is seen holding a device and Tails says: "If these readings are accurate, he's here. I found him! I just hope I'm not too late." Then Tails gets ready to jump off the cliff. He jumps off, then uses his tails to fly over to Green Hills to see where Sonic is and find him.

What happens now? We'll just have to wait for Sonic the Hedgehog 2.
