Sonic...

(Egman caused an outbreak of a virus that turns organic tissue into a metallic substance, making bodies stronger and more resilient. Fully infected subjects become zombies, losing their free will and personality traits.
Contagious and spreads quickly among people. Full infection leads to immediate transmutation, while infections from contact spread more slowly. Treatment may become ineffective if the virus mutates for long periods of time)

*Sonic also got infected and now you can see metal spots on his body, but despite the fact that he is infected, he continues to protect those who are not infected or in trouble, at some point, words flashed through Sonic's head due to the action of the virus, which made Sonic grab his head, namely these words: "URGENT .., scum .. don't come near me .., fool .., worthless, God. It would be better if I never met you" each of these words made Sonic tremble *
