that's what I've spent the last two days on.
I had the idea to change the design of Sonic's main characters to create an alternative universe.
i.e., I remade them first and on the way I came up with the idea).
even a sketch, but with a soul.

There will be a planned explosion by one villain, which will hit a small town where the heroes find. The ability to radiate this explosion is to change the design of those who will fall under it. The heroes will be able to see their true appearance only in the mirrors, than the antagonist will abuse. what is his purpose? just to mock the heroes, look at their competitions and attempts to overcome the prepared trials. after the victory over the villain, the heroes will be able to change their design and terrain around at any time, using removable rings on their finger.
Heroes grow taller due to tall platforms with heels, they also add a farther jump. earrings in the ears are removable, when touched on the ground they are transformed into holographic turbo boards for racing and quick movement. heroes have added or changed their original abilities, which I will tell more about in this article about AC.
Between several characters will be built a love line, the heroes will be replenished.

I will be glad to hear your opinion, suggestions, any - or handkanone. in the future I will invest in my idea and will make much more material.
