Sonic the Hedgehog makes cameos everywhere

Sega has never been worried about putting their most iconic character in other games. Before he appeared along side Mario in Mario & Sonic at the Olympic Games, the blue blur appeared in Crusader of Centy, an action RPG published by Atlus for the Sega Genesis, and as a horrific monster in Illbleed. Remember Illbleed? Sega published the survival horror game for Dreamcast and it was made by none other than Climax Entertainment. Zodick the Hellhog appears in the sixth level as a boss who drops rings when he gets hit.
