#1 Conor McGregor
Could it be anyone else?
The UFC’s golden boy has transcended the sport in many respects, and is single-handedly dragging it into mainstream prominence in the absence of Ronda Rousey. While his charisma and trash-talk have spewed hushed comparisions with the late, great Muhammad Ali, his take-on-all-comers fighting style backs up the hype in the Octagon as well.

Amidst rumours that a possible super fight with Floyd Mayweather could materialise, Conor McGregor has certainly shown the willingness to transgress the boundaries of the UFC and experiment with other options that would land him a big paycheck.
And the WWE presents exactly that. Although McGregor has been vocal in his scathing criticism of the pro-wrestling industry, he also alluded to the fact that he may be interested in a cross-over appearance in the WWE should the money be right.
While it remains to be seen if he will follow up on that idea, it certainly earns him the top spot on our list of UFC fighters today that can tear it up in the WWE as well.
