A thumbnail I've made for a Sonic 3 A.I.R mod I've updated called Fat Sonic Hunt, starring Sonic and Fat Sonic (who's nicknamed Gordon as well, because... why not?). And yeah, Sonic is being chased by Fat Sonic in Angel Island Act 2 here, since that was the background for the old version of the thumbnail which just used the sprites rather than being digitally made.

Sonic the Hedgehog is owned by SEGA.
Sonic 2 XL is created by Captain Bozo & Ranger.
