Sonic the Hedgehog 4 (2027) | Jim Carrey, Keanu Reeves, James Marsden | Concept Trailer Watch this Sonic the Hedgehog 4 fan made concept trailer What if Sonic Movie 4 introduced Silver the Hedgehog as a psychic time traveler sent back to destroy Sonic before the future falls apart? That's the "what if" concept I built this entire trailer around. I personally designed every storyboard and visual sequence from scratch, imagining a world where Jim Carrey's Dr. Robotnik returns with his most terrifying creation yet, Metal Sonic, a chrome plated nightmare fueled by all seven Chaos Emeralds. Keanu Reeves comes back as Shadow the Hedgehog, standing against Silver not because he cares about Sonic but because he knows what it looks like when someone gets manipulated into becoming a weapon. Kristen Bell crashes into the franchise as Amy Rose, Piko Piko hammer in hand, carrying a warning nobody is ready to hear. Disclaimer: This is entirely a fan made concept trailer created for entertainment and creative purposes only. All storyboard work and visuals were personally designed and produced by me.
