It’s all about the apocalypse featuring Keanu Reeves in the *Sonic the Hedgehog 3* **trailer**.

After a **playful cameo** as [Shadow the Hedgehog](https://www.youtube.com/watch?v=1KhKd1bj7G0) in *Sonic 2*, Reeves takes center stage this time as the primary antagonist. He’ll go up against an unexpected trio: Ben Schwartz reprising his Sonic role, Colleen O’Shaughnessey returning as Tails’ voice, and [Idris Elba shining as Knuckles](https://mashable.com/video/knuckles-idris-elba-ty-cole).

But there’s more. As the trailer shows, beloved Jim Carrey returns, taking on dual roles as Dr. Ivo “Eggman” Robotnik and Gerald Robotnik, the mastermind behind Shadow. With this much villainous presence, the stakes are at an all-time high.

Save the date—*Sonic the Hedgehog 3* races into theaters on Dec. 21.
