Interesting find while messing around in Sonic 3k's debug mode
A possible relative of ashura?!
It seems that this hedgehog changes its pallete when fighting mecha sonic (they even look a bit like shadow during the metropolis zone boss), Anyway i have decided to coin this newfound glitch character majesto due to it's ability to magically turn the hud into it's shield :P
If you are wondering how to find this hidden character, First load up sky sanctuary zone in debug mode, Then go to this pit of spikes next to knuckles and spam the 4 vertical rings all over it
Now drop sonic into the spikes and he will respawn as a bundle of hud sprites, navigate to the hyper monitor in debug mode and then break it. Congratulations you have now unlocked majesto (although you can only use this character in sky sanctuary zone unfortunatley)
