Who was the greatest “Mythical Fighter” in MMA?

I apologise if this post isn’t allowed, but when talking with some buddies after 293 we got talking about some of the “Mythical Fighters” and trying to decide which was/is the GOAT

TRT Vitor? Sea Level Cain? Motivated McGregor? Ubereem? One-eyed Bisping? Picogram Jon Jones? … I still personally maintain that TRT Vitor and Ubereem are two of the most terrifying sights to see walk into the Octagon
