Villains in Power Rangers Samurai

The villains in Power Rangers Samurai are the enemies of the Samurai Rangers. They all come from a place called the Netherworld and the Nighloks need to bathe in the Sanzu River's waters once in a while or else they dry up. The Nighloks want to flood the Sanzu River with the sorrows of humans and into the crevice from the Netherworld to the Earth.

Master Xandred

Master Xandred is the leader of the Nighloks and is armed with a broadsword. The most powerful of the Nighlok, Xandred is prone to frequent violent outbursts, usually directed at the failure of his subordinates to destroy the Rangers. He seeks to cause the Sanzu River to flood with the despair of humans, allowing him to enter the world of the living and conquer it. His rage was originally endless until he heard the sound of Dayu's Harmonium.

Master Xandred was sealed within the Netherworld years ago in a battle with the last team of Samurai Rangers led by Jayden's father, who perished after using his symbol power to imprison Xandred. Master Xandred possesses enormous strength and power, easily able to overpower the Samurai Rangers in their first encounter, and is proven to be a capable swordsman. Power energy radiates from his body that can sometimes incapacitate him but has also been shown to create new Moogers and Spit Fangs. However he displays a number of fatal weakneses as well. Because of the (incomplete) seal that the original Red Ranger placed on him Master Xandred's power is not at its peak. Not only that but he constantly suffers from a headache that only Octoroo's sake-like medicine and the music from Dayu's harmonium are able to soothe.Like other Nighlok, Master Xandred's body dries out if he's not in the Netherworld, although he dries out much faster than any other Nighlok (whether or not this is a result of the seal on him-it is never stated) and it takes longer for the Sanzu River's polluted water to soak back into Master Xandred's body.

In "The Master Returns,", Master Xandred gets even more angry then before after he is told by Octoroo of Serrator's betrayal. He plans to go to Earth through a gap. Though Octoroo advises him not to, Master Xandred makes his return to Earth planning to destroy Serrator along with the Samurai Rangers. Instantly Master Xandred starts to dry up, but he fights the Rangers anyway and completely overpowers them. Jayden goes to take him on with his Bullzooka, but Master Xandred managed to block all the shots. He is able to beat Jayden even in Super Samurai Mode, leaving him badly hurt and unable to stand up. Afterwards, Master Xandred repaired and gave Dayu back her harmonium. Master Xandred is about to completely dry up when Octoroo brings him into the Netherworld to rejuvenate, sinking to the bottom of the Sanzu River. This ends up giving Serrator the opportunity to take over Master Xandred's ship and split world in two.

He is defeated by the Rangers in the episode "Samurai Forever."

Dayu

Dayu (formerly known as Dalia) is one of Master Xandred's two followers, a female figure with a shamisen. Before becoming a Nighlok, she was a newlywed to Deker. But when a fire (implying to have been set up purposely by Serrator) burned their house down and injured Deker leaving him with moments left to live. A mysterious Nighlok appeared (later revealed to be Serrator) who offered Deker's life back in exchange for her humanity. When she accepted the deal, Deker indeed lived on but as half-human, half-Nighlok with no memory of Dayu. Dayu then became a Nighlok herself with only her shamisen (which was once her decorative lute) by her side to remind her of her past. Of all the villains, Dayu is the only one who cannot let go of her past once making an attempt to reclaim it by kidnapping brides and using their tears to create a wedding dress. Her plan failed due to the Rangers' interference, though she is saved by Deker. She is a powerful fighter as she took down both Kevin and Mia at once. Her shamisen (which she calls her "Harmonium") has a hidden short sword in the neck which she uses for battle. She has a habit throwing the baki of her instrument at Nighloks' she gets angry at. In "Broken Dreams," Master Xandred was getting tired of Dayu's failure and breaks her shamisen causing her to go to the human world and fix it with a musician. Mia pursues Dayu only for them to be put under a sleeping spell by Rhinosnorus. Mia witnesses Dayu's past in a nightmare. After the sleeping spell wore off, Dayu attacked Mia (who wanted to help Dayu after what she saw) only to retreat when Emily arrived. In "The Ultimate Duel," Dayu meets with Deker before his duel with Jayden. Around the time when the Black Box was completed as seen in "Super Samurai," Dayu abandons Master Xandred and Octoroo and goes into the human world. In "Trading Spaces," Dayu meets with an outcasted Furry Wart on a river stream where she plans to find a way to end Master Xandred's life for casting her out and breaking her harmonium.

In "Kevin's Choice," Dayu finds the part of Deker's sword and is approached by Serrator who offers to fix Dayu's harmonium in exchange for the info on where Deker is. While the two talked, it was revealed Serrator was the one who turned Deker into a half-human/half-Nighlok. Dayu is wondering if Serrator is lying until she finds Deker in the forest. Dayu learns from Deker that his sword Uramasa had taken the blow in the fight against Jayden. She and Deker crash the battle between the Power Rangers and Scarf where they attack Scarf in order to unleash Skarf's true power.

In "A Sticky Situation," Dayu receives a special dagger from Serrator.

In "The Master Returns," Dayu states her unhappiness with how long Serrator is taking to fix her Harmonium. Soon after Serrator heads to a cliff, Dayu senses her Harmonium presence and heads after Serrator. After she manages to catch up with Serrator, she fights him only to be knocked down by Serrator. After Master Xandred returns to Earth, he fixes Dayu's Harmonium and Dayu swears her loyalty once again to Master Xandred.

In "A Stroke of Fate," Dayu tries to convince Deker not to trust Serrator and Antonio begs him to reconsider his role in the battle between Humans and Nighloks following him remembering his past memories. Yet Dayu was unable to convince Deker to not trust Serrator.

Dayu is voiced by Kate Elliott in Nighlok form and portrayed by Rugen Du Bray in human form.

Octoroo

Octoroo is an elderly squid-headed figure with a staff who is one of Master Xandred's two followers. He is usually reading old books, mixing Master Xandred's medicine, or checking the water level of the river. Everyone including Master Xandred calls him "Noodle-Face." Despite his small form, he is powerful enough to take on the Gold Ranger. He also seems to be highly skilled in black magic and a gifted potioneer, as he is easily able to poison the Red Ranger singlehandedly. He is extremely loyal to Master Xandred. Octoroo also has a habit of yelling out "Ooh, Ah, Ooh!" whenever possible.

Deker

Deker is a mysterious Nighlok swordsman who doesn't remember his past and is cursed into finding the ideal opponent to duel. He is armed with the katana Uramasa and called by Xandred as the Cursed Warrior due to being half-human. Deker was once married to Dayu before becoming half-human. As a human he was a samurai and was given the blade Uramasa by Dayu. But when a house fire almost kills him, Dayu surrendered her humanity to a mysterious Nighlok, Serrator, to revive him. However this erased his memory and turned him half-human, half-Nighlok cursed to forever wander with a thirst for battle. Due to being a half-human, Deker has the ability to assume human form and transverse between the Netherworld and the land of the living without relying on the Sanzu River for survival. He considers the Red Ranger to be his greatest challenge since Uramasa's blade became radiant. In "Boxed In," Deker claims that the Ultimate Duel might free him from his Nighlok half. Deker is able to remember his past as Dayu's husband. In "The Ultimate Duel," Deker duels with Jayden while the others fought Rhinosnorus. Eventually, Jayden allows Deker to injure him allowing 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 before vanishing in a puff of smoke while falling off the cliff.

In "Kevin's Choice", Dayu finds a piece of Uramasa as Serrator arrives to prevent Dayu from throwing the broken part away. Dayu later finds Deker alive in the forest. Deker tells Dayu that Uramasa took the damage for him as she tells him about Serrator's offer. With a backup sword, Deker joins Dayu into attacking the Rangers where Deker fights Jayden stating that he is now a "sword for hire" ever since Uramasa broke. Deker and Dayu then attack Skarf in order to unleash Skarf's true power.

In "Trust Me", Deker accompanies Serrator and Dayu to Monalua, where they use a special ash to make its inhabitants paranoid. Deker fights Jayden and Mia, where Deker defeats them and states that Jayden has become weaker for relying on his teammates to help him than fighting him solo. Following Malden's destruction, Jayden uses his Bullzooka when confronted by Deker who asks if Jayden has stated fighting with blasters now. After Jayden destroys the fires spreading the ash and lifting the paranoia spell, Deker was prepared to fight Jayden only for Serrator to tell him that he has bigger plans for him. Deker than leaves with Serrator and Dayu as Serrator summons a Papyrox and two giant Spitfangs to cover their escape.

In the episode "A Crack in the World", Serrator refuses to give back Uramasa straight away. Serrator reveals his plans to Deker and promises him he will be free of his curse if he helps him.

In the following episode "A Stroke of Fate," Deker returns to the ruins of his home as he begins to remember some of his past memories. Dayu tries to convince him not to trust Serrator and Antonio begs him to reconsider his role in the battle between Humans and Nighloks, to no avail. Once Deker reobtains Uramasa, he betrays Serrator and him strikes down, leaving the Rangers to finish him off for good.

He then challenges Jayden to the Ultimate Duel once more after Jayden leaves the Shiba House in the episode "Fight Fire with Fire".

Deker is portrayed by Rick Medina (who previously portrayed Cole Evans in Power Rangers Wild Force).

Serrator

Serrator is a Nighlok with six slitted eyes and a ricus grin. He can teleport, emit electricity, elongate his claw, and wields a weaponized Shaku in combat. In "The Tengen Gate," he was referred to as the Nighlok King. He was responsible for cursing Deker by turning him into a human/Nighlok hybrid and turning Dayu into a Nighlok as seen in "Broken Dreams" where his shadowed astral appearance appeared before Dayu's human form agreeing to save Deker's life in exchange for Dayu's humanity.

Serrator officially debuted in "Something Fishy" where he had been at the bottom of the Sanzu River and was revived by Master Xandred's recent power surge. He arrives aboard Master Xandred's ship to offer his services and revealing himself to be the one who sent Switchbeast. He shows off his heightened powers by obliterating an army of Moogers with a single blast and manages to convince a skeptical Master Xandred of his loyalty and asks for permission to enter the human world to scare enough humans to flood the river. Once on Earth, he introduces himself to the Rangers, and during their battle seems to have the Rangers beat, with all of the weapons they wielded unable to affect him. Serrator even cuts a piece of paper into a shape and creates Papyrox from it. In the nick of time, Antonio arrives and manages to use the Lightzord to successfully damage Serrator. Serrator then leaves commenting that the Rangers had "passed the test" for now.

In the episode "He Ain't Heavy Metal, He's My Brother," Octoroo criticizes Serrator for failing. Briefly after this, Serrator goes to attack the city again only to be met by the Rangers. He overpowers the Rangers again. Just as he is about to finish them off, Mia arrives only to be knocked down by Serrator. Jayden then passes Mia the Black Box allowing her to go into Super Samurai Mode. She manages to damage Serrator using her Super Airway Finisher. Before retreating, Serrator creates another Papyrox which is accompanied by some Giant Moogers and two Giant Spitfangs.

In the episode "Kevin's Choice," Serrator appears before Dayu to prevent here from disposing the half of Uramasa that was broken during Jayden and Deker's battle. Serrator then makes a deal with Dayu, offering to fix her Harmounium and Uramasa as long as she help him. It was revealed Serrator was the one who turned Deker into a half-human/half-Nighlok. He has Dayu send the message to Deker who Dayu had no idea was still alive. He instructs Dayu and Deker to crash the battle between the Rangers and Skarf and unleash Skarf's true power.

In "A Sticky Situation," Serrator catches up to Deker and Dayu as Deker asks about him fixing Uramasa. Serrator gives Dayu a special dagger and tells Deker that he will play a part in mankind's destruction.

In "The Master Returns," Master Xandred learns of Serrator's secret plans and goes to Earth to deal with him. When Serrator is taking too long to get back to Dayu on repairing her Harmonium, she ends up confronting him which leads to an altercation where Serrator defeats Dayu. Luckily for Dayu, Master Xandred arrives and repairs Dayu's Harmonium upon reclaiming it from Serrator who flees. When Master Xandred is placed in the depths of the Sanzu River to recuperate, Serrator takes over his ship with no opposition.

Serrators plan is finally revealed in the episode "A Crack in The World" where Kevin notices how all his attacks form a straight line on the map. Serrator reveals during his next attack his true motives are to crack open the Earth so that the entire Sanzu River floods in, trapping Master Xandred in the Nether Worlds and heightening Serrators power to the point where he is equal to none. This will allow him to become the ruler of both worlds as well as create a new domain of his own.

To finally complete the spell starting in "A Crack in the World," he needed Deker to break the final point with his sword Uramasa. Serrator claimed that in doing so, Deker would also be free from his curse. Although he comes close to his goal in "A Stroke of Fate," he is betrayed by Deker at the last minute who only worked with Serrator to get Uramasa fixed. Knowing his plans are ruined he goes into an enraged fury before battling the Rangers once more. He is finally destroyed with the Shark Attack Zord.

Professor Cog

Professor Cog is a robot from the alternate reality of Power Rangers RPM. He can attack with Electro-Turbines and Hypno-Bolts. He and an army of Grinders escaped to the Samurai Rangers' reality to seek help from Master Xandred in order to level up the water for his boss. He says that he will help them in exchange for taking down the Samurai Rangers. With this plan, Professor Cog plans to wipe out the last people in his reality. RPM Ranger Scott Truman followed Professor Cog to the Samurai Rangers' reality. When Professor Cog attacks Scott, the Samurai Rangers joined the fight. Professor Cog then sends the other Samurai Rangers into a vortex leading to Professor Cog's reality while Professor Cog's Hypno-Bolts start to kick in on both Red Rangers causing them to fight. When the Hypno-Bolts kick in, Professor Cog and Sergeant Tread watch Jayden and Scott duel each other. After the effects of the Hypno-Bolts were negated thanks to Mentor giving them a special seal, Jayden and Scott then fought Professor Cog, who sends Sergeant Tread to attack. After knocking down Sergeant Tread, Jayden and Scott fight Professor Cog until the other Rangers returned. With help from the other Samurai Rangers, Scott Truman and Jayden managed to destroy Professor Cog and Sergeant Tread.

Professor Cog is voiced by Cameron Rhodes.

Furry Warts

The Furry Warts are a yellow furred ball-like soot settling in roof of Xandred's Junk. They attempt to be annoyingly repeating people's words while giggling.

In "Trading Places," a Furry Wart was cast out by Master Xandred and found on the river stream by Dayu.

Moogers

The Moogers are foot soldiers that serve Master Xandred. They are armed with swords and bows and are modeled after a coral and a sea anemone.

There's also Giant Moogers that are used to fight the Zords. There were also Flying Moogers for aerial attacks which first appear in "Jayden's Challenge" to assist Robtish. There are other Moogers equipped with blasters, but the even stronger ones are the Master Blasters, which have professional hats and take lots of Moogers to carry. The Master Blasters first appear in "Trust me" to assist Malden.

In "Party Monsters," the Moogers that were slain by the Rangers were shown in the Nighlok Heaven catering the Halloween party that the defeated Nighloks attended.

At the 2011 Macy's Thanksgiving Day Parade, the Moogers made an appearance attempting to kidnap Al Roker only to be defeated by the Samurai Rangers.

Spitfangs

The Spitfangs are secondary foot soldiers that resemble skull-like, eyeless, crocodile-heads with arms and legs. They can breathe fire quite readily. Like the Moogers, Spitfangs can be enlarged to fight the Zords. Each Spitfang comes in two different colors: gold and blue.

Papyrox

The Papyrox are giant kirigami-based monsters created by Serrator, who carves out their shapes from a piece of paper. The Papyrox are considered to be stronger than the Moogers and the Spitfangs. Some versions of the Papyrox wield double-bladed swords.

The first Papyrox appears in "Something Fishy" where Serrator carves out its shape from a piece of paper. It proceeds to attack the Rangers until Jayden transforms into his Super Samurai form and forms the Battlewing Megazord while the others fight Serrator. Papyrox breaks the Battlewing Megazord back into the Samurai Megazord and starts to overwhelm it. After Serrator retreats, Antonio summons the Lightzord to help fight Papyrox. The Light Megazord uses its Blazing Strike attack on it enough to stall Papyrox for it to do a Spinning Attack on Papyrox. The Light Megazord uses its Battle Disk Attack and Scatter Shot Attack to destroy Papyrox.

In "He Ain't Heavy Metal, He's My Brother", Serrator creates another Papyrox which is now accompanied by some giant Moogers and some giant Spitfangs. The Samurai Rangers form the Samurai Megazord while Jayden operates the Bull Megazord and Antonio summons the Claw Battlezord East. The three Megazords combine their Revolving Laser Blast, Samurai Strike, and Claw to Shreds Finisher to destroy Papyrox, the giant Moogers, and the giant Spitfangs.

In "Trust Me", Serrator unleashes another Papyrox with two Spitfangs to fight the Rangers following Maldan's defeat. After destroying the two Spitfangs, the Rangers form the Samurai Gigazord, which uses its Shogun Strike to destroy Papyrox.
