Green Hills hums wrong as the Chaos Emeralds start “detuning,” warping ring portals across the globe . Sonic blurs into action with Tails in the Tornado and Knuckles smashing rifts like glass . The teaser snaps: mag‑rail sprint over a neon city where drones stitch laser nets ; snowboard drop down an avalanche ridge ; oil‑rig leap as rings blossom midair ; rail‑grind across skyscraper cranes while the Emeralds flare like heartbeats .

Then the sting—an echo of Robotnik’s code forging a perfect rival: Metal Sonic, visor burning red . Water surges in a serpentine silhouette… Chaos is waking . Music hits the Green Hill riff, faster, louder. Final frame: gold light floods the sky—quills rise—Super Sonic blinks in. “Let’s roll.”
