Sonic the Hedgehog 2 (movie)
In a mid-credits scene, G.U.N.'s forces have arrived at the site where the Giant Eggman Robot was destroyed. At the site, Walters is informed by his agent that they have been unable to find Robotnik. While Walters is sure that Robotnik could not have survived and bids him "good riddance", he does not notice Stone, who has disguised himself as a G.U.N. soldier, having survived himself to sneak away undetected. Walters is then informed by his agent that as they were removing Robotnik from their databases, they found a file dating back to over fifty years ago. This file contains coordinates to a well-hidden black site, and Walters realizes, much to his dread, that it concerns "Project Shadow". Meanwhile, in a remote research facility, a capsule slips out, inside of which a black hedgehog named Shadow awakens, his eyes crackling with chaos energy.
