Welcome to Sonic Retro, the largest ad-free collaborative online encyclopedia for all things Sonic the Hedgehog. We currently are working on 7,420 articles and have many more that are requested to be worked on.
While this wiki is designed to help the community by being the most comprehensive collection of Sonic information on the Internet, it's nothing without the community behind it. Anyone who registers an account can edit the wiki, and help to make it the best it can be. As you feel more comfortable with the site, please feel free to make any changes or additions that you feel necessary.

Games, prereleases, and more
From the original Sonic the Hedgehog to Sonic Frontiers and beyond, we focus on where it all began: the video games. We also cover the many game prototypes that have to come to light over the years. But we don't stop there. All things Sonic have a place within, including comics, TV shows, books, music... and Sonic Boom.
