Shadow (+ Dark Sonic)

Sonic had his own personal base, with various units, from military to power and medical. Many morphs worked for him, and also his closest ones: Tails, Knuckles, Amy, Sticks, Silver, Blaze, Rouge, and only they helped Sonic in battles. Sometimes Shadow helped them. In one of the battles against Eggman, they started losing. Everyone was still conscious, but they couldn't move. Many were bleeding, and Sonic was still standing. And he got VERY angry. The atmosphere in that place became incredibly tense, and everyone looked at the blue hedgehog until a dark aura surrounded him. He raised his head and looked straight at Eggman, and suddenly, in an instant, he transformed into his dark form: his pupils and irises disappeared, his needles darkened to a dark blue, almost black. Everyone gasped - they had never seen him in this form before.
He destroyed all the robots and then killed Eggman himself. Shadow witnessed the murder. Sonic began to fall, turning back into his normal self. The black hedgehog ran to Sonic, picked him up, and, using the blue one's communicator, called for an army to bring the rest of his friends back to the base.
