This is a screenshot of the Illbleed game.
There's a demon in it at one point, but it's clearly made to resemble Sonic. Here, a character faces off vs. it so you can see it's navy blue, wearing white gloves, having a somewhat Sonic-shaped body, it has the mono eye with green eyes,
as well as similarity with the lower face. Instead of spikes though, it has bat wings, plus another pair on the back. It may have been called Zodric the Hellhog and if you hit it, rings come out. It's interesting that someone would model an enemy monster after Sonic.
