Undisputed II: Last Man Standing is a B-movie sequel to Undisputed, directed by Isaac Florentine from 2006.This time, Chambers is upgraded from a Villain Protagonist to an Anti-Hero, and is played by Michael Jai White. In this particular setting, Mafia-types run the prison fighting organization of a particular Russian prison and make money off of it. They frame Chambers for drug use so he will be sent to jail and they can pit him against their own resident champion, Yuri Boyka (played by Scott Adkins). For a while, Chambers refuses to fight Boyka, but they promise he will be freed. So he agrees. As you can see, it's fairly similar to the plot of the first movie.
This film has the examples of:
- The Ace: As the most complete fighter in the world, Boyka is crazily proficient in striking, dodging and grappling. The only way to beat him is training to become another Ace.
- Alas, Poor Villain: yes, Boyka has his faults; in fact, they are many. But his scream after Chambers breaks his knee is heartbreaking all the same.
- Artistic License – Martial Arts: The fights are supposed to be vale tudo, but their choreography is embellished to pro wrestling-esque levels, with lots of flips, spinning kicks and improbable strikes. Also Chambers is somehow able to learn effective grappling in few days with a wheelchair-bounded old man as his only sparring partner.
- Bad Boss: Boyka's training method consistst mainly in brutalizing his obedient mooks.
- Beat Them at Their Own Game: During their first fight, Boyka tries to beat Chambers with only fists, but he ends briefly knocked out. Consequently, he drops the handicap off and starts to use his legs to work Chambers over.
- Chekhov's Skill: The kneebar variation which Nikolai teach to Chambers, who later uses it to break Boyka's leg.
- Diving Kick: Boyka pulls some.
- Good Old Fisticuffs: Chambers's fighting style.
- Karma Houdini: Gaga, the evil mastermind of the film, leaves the film with millions in his pocket.
- The Last Title: Used as the film's subtitle.
- Old Master: Nikolai becomes one.
- Real Men Love Jesus: In a negative, almost frightening light. Yuri seems to be a devout member of the Russian Orthodox church, but it doesn't stop it from killing people nonchalantly.
- Surprisingly Happy Ending: To Chambers and Nikolai, at least.
- Training from Hell: By Chambers in order to beat Boyka.
- Wicked Cultured: Boyka plays chess and collects stamps.
- Wrestler in All of Us: Boyka nails his first opponent with a springboard headlock takedown, and later, during his training, he performs a hurricanrana to one of his henchmen.
- You Have Failed Me: After knowing Chambers was drugged, an enraged Boyka kills two of his cornermen, who were the plotters of the ruse.
