Even though audiences still have two years to wait for Sonic the Hedgehog 4, there is a brilliant TV show adaptation worth checking out in the meantime, Sonic X. The Sonic the Hedgehog timeline is a complex one, seeing as there are so many titles to take into consideration. Since the release of the franchise’s first game back in 1991, there have been loads of live-action Sonic movies and TV shows, the most notable being the three films that have been released across the last few years.
