We already know that Sonic the Hedgehog 2 is in production but the plot details have not yet been revealed. Interestingly, the description for the sequel has leaked and it confirms the arrival of Knuckles.
It's no secret that Sonic's video game friends will show up in the second movie. The mid-credits scene for the 2020 flick already offered a glimpse at Tails and fans believe it's only a matter of time before Knuckles shows up as well. However, it looks like the red echidna will not be on Sonic's side.
The leak comes from the U.S. Copyright Office which features the plot synopsis for Sonic 2. The description actually confirms that Knuckles will team up with Dr. Robotnik while Sonic decides to work with Tails.
The plot synopsis for Sonic the Hedgehog 2 reads as follows:
"After settling in Green Hills, Sonic is ready for more freedom, and Tom and Maddie agree to leave him home while they go on vacation. But, no sooner are they gone, when Dr. Robotnik comes back, this time with a new partner, Knuckles, in search for an emerald that has the power to both build and destroy civilizations. Sonic teams up with his own sidekick, Tails, and together they embark on a journey to find the emerald before it falls into the wrong hands. Being directed by Jeff Fowler, and starring Jim Carrey, James Marsden, and Ben Schwartz."
Knuckles' debut isn't exactly a huge surprise but the confirmation is still a welcome one. Needless to say, we can't wait to see him in action in the sequel.
Sonic the Hedgehog 2 is still in production but is already scheduled for release on April 8, 2022.
