UFC fighter with the most rematches.

Travis Fulton deserves a special mention for all his rematches.(even if they weren't in the UFC)

He rematched about 15 different guys, fighting many of them 3,4,5+ times.
He even fought 1 guy(Rory Prazak) 9 times!!! 6xMMA 3xBoxing

You have to remember that only the 2nd and 3rd fights in the series count as rematches. So if you're adding them up there is 2 rematches between Liddell and Couture and so on.

Edgar looked like he was well on his way there.

If he beats Aldo, Aldo would be more than entitled to a rematch.

I think Forrest is going to be in the Top 5 most rematches in UFC category. He fought Bonnar twice, Rua twice, Tito thrice, was scheduled to rematch Sonnen (and very likely will fight him before retiring), and (this is a stretch) will probably fight Bonnar for a trilogy no one wants to see.
