I've had some thoughts recently with regards to Super Forms; given they're caused by the Chaos Emeralds, I thought it'd be more interesting if (at least at first), they amplified one's inner Chaos. Could even provide a place for the "Dark Forms" of old as an inperfect Super Form before eventually mastering it to become the perfected Super Forms we're familiar with; all the power, but none of the control or restraint; just feral, primal violence.
