Unlike its predecessor, Sonic the Hedgehog 2 only has one post-credits scene; however, it's more epic than both of the first movie's combined. Following the initial stylized credits, a mid-credits sequence takes viewers back to the battleground where Sonic, Knuckles, and Tails defeat Dr. Robotnik in the final act.

Once the Guardian Units of Nations (G.U.N.) arrive to survey the area and search for Robotnik, viewers catch a quick glimpse of the mad scientist's right-hand man Stone (Lee Majdoub). But that's not all — no, the best reveal is still to come.

A G.U.N. agent soon informs Commander Walters that she found a file containing coordinates to a research facility, which houses none other than the icon himself, Shadow the Hedgehog. Then, we get our first look at Shadow before the screen cuts to black.
