Forum:"super" and "hyper"-??

the difference between "super" and "hyper" never seems to stabilize, they changing and disappearing per re-telling of the story(same w/ alot of other elements, but for now...) what are all the differences and requirements collectively? if all such forms for Knuckles involve being pink then why/where do i recall once seeing a gold/yellow version opposite a gold/yellow sonic in a sonic advertisement? not a fanart-an actual advertisement.
