So, this is technically 2 AUs mixed in one, technically making 3 altogether, but I wanted to share this older concept piece I had made of this particular... Set of projects?

Sonic, Shadow and Silver as "Androids", the ultimate lifeforms of their universe. They are named Cast Iron (Silver) and Cobalt (Sonic) respectively.

Shadow is the only one with the better timeline, as Cast and Cobalt were made AFTER world ending events occurred.

Cast has Ghost (Sonic) and Smudge (Shadow), Cobalt has Blotch (Shadow) and Stripes (Silver).

I will be redoing these particular designs a bit, redoing this image and such. Either way, fun is in store with these ones. :]
