1. Superman vs. DoomsdayThe good guys are supposed to win in the end, but after three solid rounds of being controlled on the ground, John Doomsday Howard surged to earn a final-seconds TKO over Dennis Superman Hallman at the TUF 10 Finale.2. El Dirte vs. FilthyThe referee tells fighters to keep it clean, but there was no chance of that happening when Joe El Dirte Doerksen met Filthy Tom Lawlor at UFC 113. Doerksen pulled out the win via the equally-uncouth-sounding rear-naked choke.3. Lightning vs. ThunderThese two weather-related phenomena usually go hand in hand, but on Saturday night they’ll go head-to-head as Yushin Thunder Okami faces Hector Lightning Lombard at UFC on FUEL TV 8. 4. Tiger vs. The GazelleThe Octagon has hosted plenty of animal-kingdom-themed matchups, like The Hippo vs. The Snake and Big Dog vs. the Sabretooth. Yet no pairing was a more perfect metaphor for MMA’s predator-and-prey nature than Yves Tiger Jabouin’s UFC 140 win over Walel The Gazelle Watson.5. The Machine vs. The Korean ZombieIn a post-apocalyptic wasteland, will robots rise or will the undead rule the earth? No way to know — yet — but a UFC 140 sneak peek saw The Korean Zombie Chan Sung Jung quickly dispense with Mark The Machine Hominick.6. The Doberman vs. The MessengerScore one for the mailman as Jared The Messenger Hamman defeated CB The Doberman Dollaway in a UFC Live 5 clash built on this decades-old, cross-species rivalry.7. The Polish Experiment vs. The American PsychoEach country-claiming weirdo went 1-1 during Stephan The American Psycho Bonnar and Krzysztof The Polish Experiment Soszynski’s duo of bouts at UFC 110 and UFC 116. 8. Hitman vs. Natural Born KillerMartin Hitman Kampmann took on the Natural Born Killer Carlos Condit in the April 2009 UFN 18 main event between two career murderers. Kampmann got that decision win, but the NBK went on a tear,  scored the division’s welterweight belt and has only lost once since then, to welterweight king GSP. 9. The Immortal vs. Lights OutMatt The Immortal Brown and Chris Lights Out Lytle’s nicknames represent opposite states of human consciousness. And while Brown didn’t go lights out, he did tap out at the hands of Lytle twice during their careers, most recently at UFC 116.10. Bang vs. The DamageAn injury stoppage was the unfortunate — if foreshadowed — outcome of the UFC Live matchup between Duane Bang Ludwig and Darren The Damage Elkins, which left Ludwig with a broken ankle.
