Ray the Flying Squirrel in Sonic the Hedgehog is a fan-made ROM of the game Sonic the Hedgehog for the Sega Mega Drive/Genesis, featuring the character Ray the Flying Squirrel in place of Sonic the Hedgehog, the game's usual protagonist. The creator of the hack is Fabricechaotix.

Ray the Flying Squirrel has a air glide move similar to Knuckles but the air glide does no damage when touching enemies. The air glide also does not stop when touching walls. Unlike many Sonic 1 hacks there is no spin dash move.
