Sonic's wind transformation!

In order to Sonic achieve this form, he must wear those wind bracelets. They hold the power of the wind, which Sonic can manifest and transform into his wind form!

In this form, Sonic can stretch and twist (like a tornado) since his whole body is made of air, but the bracelets cannot be too far of, or else they drop from his body (like magnets for his wind body specifically) and he turns back to normal. So basically the only solid thing are the bracelets and his gloves & shoes (think of his movement to be like rayman's, except that he has no limits at all since his head and body are also air)

BUT, just because he's air, he's not invincible. As I wrote above, he turns back to normal if the wind bracelets are too far off from each other, and also if they're broken or have their power disabled (Eggman would totally invent something to trigger that to defeat sonic).

Also... If he manifests the energy of the chaos emeralds in this form, he can get lighting powers as if he becomes a thunderstorm! But I think this would better suit Shadow's version of this form.

If I ever make a Sonic fan game, I'm adding this transformation!
