Cristiane "Cyborg" Justino: Although she seems closer than ever to landing a UFC contract, fans have always held a general distaste for Cyborg and her manly persona, particularly during the time of her partnership with former manager Tito Ortiz.
Cyborg confirmed the suspicions of many naysayers when she tested positive for the anabolic steroid stanozolol after her featherweight title fight at Strikeforce: Melendez vs. Masvidal in December 2011.
Justino must now prove that she can drop to 135 pounds without the help of any illegal substances. If she can't get to 135 and eventually strike a deal with the UFC, Cyborg will remain unpopular with the masses.
War Machine: War Machine, formerly known as Jon Koppenhaver, sadly possesses the grit and talent to compete in the UFC's cutthroat lightweight division.
Unfortunately for the 32-year-old Californian, living an outlandish lifestyle that includes stints in both jail and in the pornography business just doesn't jive with a career in the UFC.
But it's not necessarily his actions that make War Machine an unlikable character. Truth be told, fans just can't stand Koppenhaver's relentlessly unapologetic nature or his propensity to keep bouncing back from states of misery.
War Machine started a two-fight winning streak in Bellator MMA following his latest stay in jail. To the delight of his critics, however, War Machine naturally dropped his Bellator Season 9 Welterweight Tournament semifinal bout with Ron Keslar via first-round submission in October.
