20 Wild Theories For Upcoming Movies
17. It Features Time Travel - Sonic the Hedgehog 4
There's a pretty plausible theory doing the rounds that Sonic the Hedgehog 4 is going to introduce time travel to the live-action movie franchise.
For one, the recently released teaser trailer features voiceover from Dr. Robotnik (Jim Carrey) as he says, "You think your world is safe, but your time is about to run out."
Beyond that, it seems clear that the film is drawing huge influence from the video game Sonic CD, whose plot famously revolved around time travel.
In addition to Sonic 4 featuring Amy Rose (Kristen Bell) and Metal Sonic, both of whom were introduced in Sonic CD, the teaser trailer also featured a snippet of Sonic CD's theme song, Sonic Boom.
This all adds up to a persuasive argument that Sonic 4 will revolve around timey-wimey shenanigans, likely explaining the sudden arrival of both a Metal Sonic army and Amy at the very end of Sonic 3.
Time travel would also provide an easy explanation for Robotnik's re-emergence despite both prior versions of the character seemingly dying at the end of Sonic 3.
