Shadow

Shadow married Emily the hedgehog, but she refused him at the wedding because she no longer felt anything for Shadow and she found another man. Shadow accidentally met a corpse in a cemetery that came to life and they found themselves in an underground city. It was similar to the city in which Shadow lived with his friends Sonic, Amy, Tails, Knuckles, Rouge, Omega and others, but underground lived the dead who had already died, and all the animals were living skeletons, birds and dogs were ghosts, and black cats and crows were the same as in the world of the living, and there were many blue and white butterflies that glowed.

Shadow is a humanoid black hedgehog with red stripes on his quills, arms, legs, and eyes (they look like arrows on his eyes). He wears aero sneakers on his feet and gold ring-bracelets on his arms and legs. He is a higher life form from the Sonic the Hedgehog universe.
