Not to draw the equivalency between MMA and pro wrestling again, but Jon Jones, Conor McGregor, T.J. Dillashaw, Chris Weidman, and Daniel Cormier are not bizarre names, but they're memorable. Fabricio Werdum only sounds exotic because he's Brazilian.
If we go back to UFC's biggest stars historically, Georges St. Pierre looks cool in print, but he's also French Canadian. Tito Ortiz, Frank Shamrock, Ken Shamrock, B.J. Penn, Matt Hughes, Chuck Liddell and Anderson Silva all have fairly normal names.
The idea of giving a guy like Braun Stroman a weird name works if you actually have plans for the guy. But Braun Stroman is going to be lucky to be Erick Rowan in 9 months, so what's the difference between naming him Braun Stroman or Miles Henderson?
