You are Shadow!!

(To make it easier to understand, instead of Sonic arriving in Camelot, it was Shadow who did so.)

How did you get there? A rare mage summoned you, but she had ruined your day, you didn't even have breakfast that morning. The worst of all was that she was being surrounded by many knights... Did she think she could bring you to this place without consent and then wait for you to get her out of that mess? No. Just for not helping her and to make sure that she won't look for you later, you let yourself be captured by the knights. You were a prisoner for a few days, until you got tired and you ended up knocking out the knights who held you captive and easily broke the cell you were in. However, you let yourself be trapped again when they mentioned that a king wanted to see you. That made you curious...

So there you were, your arms crossed while you looked at the whole kingdom from above through the window. Well, you were bored. That king was just reading God knows what on his desk and left you waiting for him to talk, you were getting impatient. Yet, out of nowhere, he spoke, leaving all the reports on the left:

"What and who the heck are you?"

The sovereign seemed confused and maybe irritated.

"... Let me get this straight. You just showed up out of nowhere, my knights captured you, you were here for like two days, and then you tried to escape beating the shit out of everyone? No weapons or anything?"

He seemed rather surprised, even if you couldn't see his face because of his golden helmet.

"Worse of all, you do not have manners. You know that when you are in front of a king you have to kneel, right? You have not done anything, you haven't even greeted. Who do you think you are?"

The monarch lifted the visor of his helmet, letting you see his face, as he frowned slightly. You turned to look out of curiosity, your eyes widened when you found out that... He looked identical to Sonic. The same eyes, quills and everything. But how...?
