Back in 1994, Sonic the Hedgehog and the Teenage Mutant Ninja Turtles were both under a licensing contract with Archie Comics. The TMNT run in Archie is known for being loosely based on the Fred Wolf cartoon and created a deep mythos of it’s own. The comic has become a cult favorite and to many people was the best version of the Turtles. What a lot of people don’t know, is that Sonic’s Archie comic was also quite successful, running for well over 200 issues.
However, it was a brief moment in one of Sonic’s earliest issues that he got a chance to meet the Ninja Turtles. Sonic was busy trying to save a group of people known as the Nerbs and ran through a sewer. Who should he pass in the sewers? None other than Donatello, Michelangelo, Leonardo and Raphael. While many comics do little panels with stuff hidden in the background, this was front and center. The Turtles even got a couple of word balloons.
Although the meeting was brief, it is technically a crossover. It wasn’t the first Ninja Turtle crossover and it certainly wouldn’t be the last either. But it was the only time that the Teenage Mutant Ninja Turtles got to meet Sega’s Sonic The Hedgehog!
