Sonic leaping at you from a fade background. Another nice design that won't fit.
At the right is one if you like cute! Look at all of Tails' expressions, and Sonic too! This is a cute showcase for our heroes.
For the grey one, Sonic looks like he is powering up or something infront of a black & white of the rest of the cast.
This is a re-release design with blue cuffs and collar for the summer. The blue energy-charge around Sonic is glitter.
