Cosmic Fall
After Shadow had defeated Black Doom, he had got all the Chaos Emeralds.
"I am Shadow the Hedgehog, a research experiment gone horribly wrong." He said. "With all the destruction I have caused, I should have never been created. This is Who I am."
Suddenly, Blaze showed up.
"Who are you?" Shadow asked, because he never met Blaze before.
"I am your guardian angel, Blaze the Cat." Blaze answered.
"Where are your wings?" Shadow asked.
"I have not earned them yet." Blaze replied. "So, you wished you were never created, and I will grant your wish. You were never created, you don't exist."
Shadow had to go through life and see what everyones' lives would be like if he was never created...
