Who is this???

I guess it's not shadow then cause he's smiling

It’s AI so I get how it’s confusing, but you can tell by some aspects of the design that it’s Sonic. The lack of the red stripe on his top quill, as well as blue being the main colour of his body. Red was used for both shading and contrast, as well as the whole flame motif it has going on.

sonic im p sure shadow has a red stripe down his head

idk my sonic characters, but thats totally shadow I THINKK
