there's kh3 cracktheories in here and i can't think of a better title

I made a joke that all three of those characters are Xigbar and then I realized

What if they are? We already know that Xigbar is Luxu. But some people think he also might be Brain? And I think if he's Brain, then Brain is actually Luxu from the future, traveling back in time to change the past, meaning the 'Luxu' of that timeline doesn't know that Brain is actually himself. Some people also thought maybe Xigbar was the Master of Masters, before KH3 came out and they learned he was Luxu. But who's to say he didn't also go back in time and became the MoM, unbeknownst to both his Luxu-self and Brain-self?

Which means that Xigbar is the MoM is Patrick
and Xigbar is Luxu is Spongebob
and Xigbar is Brain is Squidward's House

This is my most groundbreaking theory since Plutonort.
