The Ultimate Duel is the twentieth episode and season finale of Power Rangers Samurai. It is the fourth episode of the Black Box arc. The episode focuses on Deker's long desired duel with the Red Samurai Ranger.
Continuing from the end of Broken Dreams, Deker demands Jayden to duel him. Jayden tells Deker he only fights to protect the innocent and not out of amusement. Deker gives him 24 hours before they duel or else his Nighlok side will start attacking innocent people, should Jayden fail to show up. Kevin and the other rangers try to talk Jayden out of fighting Deker alone and instead defeating him as a team. Jayden refuses and tells them he must be the one to duel Deker or Deker will never give up. Just as Jayden prepares to leave the next day, Rhinosnorus attacks once more and Jayden puts Kevin in charge of leading the team while he fights Deker. The Rangers defeat Rhinosnorus while Jayden battles Deker. The battle rages on, with both combatants evenly matched. Eventually Jayden allows Deker to injure him to get close enough to finish Deker off. Deker's sword Uramasa is broken and half of it gets struck into the ground nearby. Deker thanks Jayden for the Ultimate duel, which has apparently released him from his Nighlok curse, before vanishing in a puff of smoke. Back at the Shiba house, Jayden thanks Kevin for leading the team in his absence as they all celebrate their victory.

Knowing Jayden is still weak, Antonio tries to stop Deker, but he challenges Jayden to a personal duel. Jayden says that he cannot accept the challenge as he is a samurai who protects the innocent.

- When Jayden hands Kevin his Secret Discs so they can form the Megazord without him, he hands the Lion Disc and the Beetle Disc instead of the Tiger Disc. Jayden trusted the Beetle Disc to Mia, who then gave it to Mike in Forest for the Trees.
- Jayden should have given his Lion Folding Zord to complete the Megazord, as the discs only power up their weapons and allow them to transform to their special weapons when they're using it.
- When Kevin pulls out his Hydro Bow, the Dragon Disc is on backwards.
- Right before the Rangers perform the Megazord finisher, the Samurai Battle Cannon can be seen in front of Rhinosnorus. This is due to footage from Shinkenger.
