From Sonic Retro
We don't usually document debug mode bugs but I'd be willing to make an exception for this one, given that it sprouted legs. I don't think it's right to consider it a "Sonic character" though.
Once upon a time I made an image with (what I thought was) all the possible palette combinations you could get from this glitch. It circled the internet for a bit, but I think it's disappeared. -Black Squirrel (talk) 17:17, 21 October 2019 (EDT)
Honestly Ashura holds too much status as that one obscure yet known palette glitch to be merged with all the other stuff, especially considering Ashura's palette also appears in Sonic 3 according to Cybershell, haven't checked myself but the footage shows him using the exact same colours while transforming into Super Sonic for the second time. I mean this fella even had his own edgy as hell fangame in the works at one point in time, ya really wanna merge discount Scourge? -Dense (talk) 09:46, 5 December 2020
