What if there is a Sonic game with Dark Super Sonic from Sonic X? Dark Sonic would be from the Negative Energy from the Chaos Emeralds and it would bring out Sonic's inner rage. It would be similar to how the Symbiote Suit brought out Spiderman's inner rage and made him more aggressive. But Dark Super Sonic wouldn't make Sonic a jerk and do a stupid dance to some James Brown song.
