The Shadow Dynasty
(Note: This is based off of the GUN Fortress Hero Ending)
Shadow the Hedgehog was very happy. He had all seven Chaos Emeralds in his hands, plus he was satisfied with his past for who he was.
And being emperor of the planet Earth didn't hurt either.
Shadow had access to a huge palace built over the ruins of the GUN headquarters, almost unlimited wealth, and power over billions. Yet he somehow felt incomplete.
Like there was something missing. He closed his eyes, yet could not come up with what was missing. He then shrugged it off. He was Shadow, ultimate life form!
