The first teaser for Sonic the Hedgehog 4 is out now, teasing what is to come in the fourth entry. Amy Rose and Metal Sonic are the big new additions to the film, with Sonic the Hedgehog 3‘s post-credits scene showing Amy assisting Sonic in a fight against an army of Metal Sonics. However, cast members like Matt Berry, Ben Kingsley, Nick Offerman, and more have also joined the filming, filling out the sequel’s all-star cast.
Sonic the Hedgehog 4 May Adapt Sonic CD’s Time Travel Story

Like most of the early games in the franchise, 1993’s Sonic CD didn’t have the most fleshed-out story. However, Sonic the Hedgehog 4 may be adapting every element of the game’s narrative. Firstly, Sonic CD is the game that introduced Amy Rose and Metal Sonic. The fact that both of these characters are appearing in the fourth Sonic movie is a big sign, meaning that the framework is already there.
However, Sonic CD introduces one other element that may make Sonic 4 the weirdest movie yet: time travel. In the game, Sonic is able to travel through time, allowing him to go to different versions of stages. One of the few lines of dialogue in the Sonic the Hedgehog 4 teaser is Robotnik saying, “You’re running out of time.” With how short the teaser is, it would be an awfully weird coincidence for one of the few lines to reference time. The more likely explanation is that Sonic the Hedgehog 4 will actually feature time travel.
The appearance of the Metal Sonics and Amy in the Sonic 3 post-credits scene seemed out of nowhere, as Sonic was in a random forest when they showed up. However, it makes perfect sense for this to be caused by them traveling back in time to when Sonic was there. Amy and Metal Sonic could be from the future, with both of them knowing that Sonic and his friends are key to stopping some future threat.
