#3 Anthony Johnson
Anthony Johnson is one of the ‘baddest’ men on the planet, and if you don't believe that then you're seriously kidding yourself. The guy is one of the most lethal knockout artists in the history of the UFC, and his abilities inside the Octagon are nothing short of phenomenal.
If you want a Royal Rumble entrant who is going to completely run through the men stood in front of him, then Johnson is the way to go.

Of course, in terms of name value, a lot of people may not place much stock in this guy. However much like Rusev back in 2014, after 30 seconds you'll know exactly why you should get behind him. It seems like only a matter of time until Johnson becomes World Champion, and before that day comes WWE needs to capitalise on his momentum.
From one of the scariest possibilities to one of the most entertaining.
