Shadow is enemies with Infinite and despises Infinite for what he does now to other mobians and how he treats his enforcers

Shadow is a black-furred mobian hedgehog. He has red eyes, a patch of white fur on his chest, a black nose, a tan muzzle, and small, triangular ears with tan canals. He also has six quills on his head, four of which curve upwards while the other two curve downwards, two spines on his back, and a short, pointy tail. He has red stripes on each of his head quills, around the edges of his eyes, and on his arms and legs.

Infinite knows Nemesis had been secretly helping the resistance and other refugees and so now has cut off ties with Nemesis.

Shadow knows Sonic and that Nemesis body type looks eerily similar to Sonic. He also knows that Nemesis doesn't seem to be entirely loyal to Infinite.
