List of Power Rangers Super Samurai episodes

The Rangers become concerned by the extent of the Sanzu River when water from the Sanzu River begins to seep into our world. Meanwhile, Arachnitor resurfaces and uses the water to prevent himself from drying out. At the Shiba House, Antonio works on the Black Box. After he completes it, he rushes to where the other Rangers are. The Rangers battle Arachnitor and Antonio finally makes it there. He informs Jayden and the others that he has finally unlocked the Black Box. Jayden uses this new power to access his Super Mode and defeat Arachnitor. Once Arachnitor grows into a mega monster, they use a new cannon to destroy Arachnitor.

A depressed Antonio sits in front of a lake when he gets a distress call from Jayden, stating they need his help. While the Rangers are fighting some Moogers, Antonio appears and he morphs. He pulls out the Barracuda Blade, and cringes in fear at the sight of it, seeing a fish in its place. After the Moogers are defeated the Rangers make sure Antonio is okay and Antonio reveals he's been afflicted with a debilitating fear of fish. Meanwhile at the Sanzu River a new villain, Serrator appears and offers help to Master Xandred in his plans and reveals that he was the one who sent Switchbeast to Master Xandred. Master Xandred is skeptical at first but when Serrator proves his loyalty to him he is accepted. Back at the Shiba House the team tries to help Antonio out with aversion therapy, Jayden is afraid of spiders, Mike is claustrophobic, and Mia is afraid of frogs. After that attempt fails, the Gap Sensor goes off and the Rangers rush into action. Antonio stays behind, and Mentor Ji shows him the LightZord, an ancient Zord that no Ranger has been able to master and Ji aks Antonio to see if he can unlock it. The Rangers deal with two Spitfangs before Serrator destroys the monsters and personally tests the Samurai rangers' fighting skills. Serrator effortlessly defeats the Rangers in battle. At the last second, Antonio arrives with the Lightzord to drive Serrator off before enlarging Lightzord to take out the Papyrox. Later on the Rangers ask Antonio how he got over his fear, he tells them and they laugh as it is shown that Mentor Ji had snuck up behind Antonio and stuffed a sushi in his mouth having him eat it.

At the Shiba House, with Antonio having conquered his fear of fish Emily and Mike decide to keep the stray kitten as a pet. The Rangers are surprised to see Antonio and Mentor Ji working collaboratively to store the Shark Disk (which is capable of defeating General Gut) with the Light Zord. Mike plays a prank on a distracted Antonio by putting dry cat food in his plate of trail mix but is caught by Mentor Ji who gives Mike a taste of his own medicine before deciding to continue working on the Disk outdoors, free of distractions. Meanwhile at the Sanzu River, Octoroo announces the return of the powerful Nighlok Eyescar to Master Xandred, who has a plan to trap the rangers. Upon completing the Shark Disk, Antonio and Mentor Ji are kidnapped by a swarm of Moogers. With the Gap Sensor sounding the rangers head to investigate their disappearance. While following the trail left by Antonio's dropped reel the Rangers are ambushed by a large amount of Moogers. Mike figures out there is something within the Light Zord and unleashes it, which turns out to be the Shark Disk. This allows Jayden to access Shark Attack Mode to destroy all the Moogers effortlessly. Eyescar eagerly awaits the arrival of the Rangers with his massive Mooger army, outnumbering the Rangers a hundred to one but Jayden having anticipating the situation, enters the fray with the Samurai Battlewing destroying most of the Moogers with an aerial assault. The Rangers then move in and rescue Ji and Antonio before defeating Eyescar together. When Eyescar returns to life as a mega monster the Rangers use the Shark Sword to finish him off. Back at the Shiba House, Antonio and Mentor Ji thank the rest of the team for their help and Mike attempts to try the same prank again on Antonio only to be caught by Mentor Ji again.

Kevin loses his Samurizer in an attack by the Nighlok Skarf (who eats it) while out in town near the local swimming center where a swim meet is being held. There, he reunites with one of his old swim team members and begins to have thoughts that he should return to swimming, as his friend is not as good as he was, and his Samurizer is still missing. Mike calls Kevin's Samurizer so they can track down Skarf, discovering the Samurizer is in the Nighlok's arm. Elsewhere, Dayu finds a part of Deker's Uramasa as she is approached by Serrator who tells her where she can find Deker so they can serve under him in exchange for Dayu's harmonium and Deker's Uramasa getting fixed. Dayu and Deker enter the fray with Skarf so Deker (who is wielding a different sword) may fight Jayden in his Super Samurai mode. However, Dayu and Deker end the fight prematurely by destroying Skarf (since Serrator mentioned that the destruction of Skarf can unlock his secondary power), giving the Rangers the chance to retrieve Kevin's Samurizer. When the Nighlok enlarges, he gains a shield, forcing the Rangers to form the Samurai Gigazord for the first time, with Jayden using Shogun mode to break through the shield and destroy the Nighlok. Later, Kevin goes to the swim meet to see his old friend win after using Kevin's advice.

Kevin notices that the places that Serrator’s Nighloks attacked prior all form a straight line. On Master Xandred’s Ship, Serrator summons the Nighlok Pestilox to attack at the appropriate locator point. Antonio catches a large fish at the docks and takes photos of it at a nearby photo booth. Back at the Sanzu River, Octoroo confronts Serrator after discovering his 200-year plan. Octoroo learns that Serrator was wedging sadness in a pattern. Serrator is impressed reveals that Deker is an important tool in his plan. In the forest, Dayu informs Deker that she doubts Serrator will keep his word but Deker merely tells Dayu to stay away from Serrator. Pestilox begins his assault and Mentor Ji calls Antonio to battle. Pestilox fires insects into the mouths of the citizens causing them great stomach pain. Bulk and Spike decide to take a break from their training to eat and they notice the injured citizens and the Nighlok. Pestilox turns his attention to Bulk and Spike. The Nighlok fires the insects towards them but they hide in the Photo Booth. Suddenly Spike feels the same pain, but it is merely an empty stomach. Bulk and Spike move the photo booth towards the food. Several photos are taking during their journey and lunch. Pestilox enjoys his victory until the Gold Ranger makes his appearance. The Gold Ranger attacks Pestilox while the other Rangers and Moogers join the fight. Pestilox fires the insects towards them. Green Ranger blocks the attack with the Forest Spear. Red Ranger fires the 5-Disc Cannon, but the attack is blocked by Serrator. Super Samurai Red Ranger and Rangers Pink and Yellow work together against Pestilox while the others fight Serrator. Deker arrives to the scene with his Temporary Sword aimed at Serrator's back. Serrator tells Deker how the recent Nighlok fights have created the opening for his ultimate plan: To flood the entire Sanzu River into the human world and thereby allow him to become the ruler of both worlds. Super Samurai Red Ranger fires the Super Bullzooka and defeats Pestilox who grows to his Mega Mode form. The Rangers form the Samurai Megazord to face off against Pestilox. Serrator goes into details about how Deker's role as a half human, half Nighlok is important to the mission. Pestilox is defeated when the Rangers form the Claw Armor Megazord and Jayden powers up to Shogun Mode. Dayu overhears the conversation with Deker and Serrator. Deker who simply wants Uramasa back is uninterested in Serrator’s plan but Serrator tells Deker that by fulfilling the true purpose of the sword his curse will be lifted. Serrator's plan starts as energy blasts emit from the ground at the wedge points. Serrator floats in the air and admires his near victory. Deker falls to the ground. Jayden tries to stand up, but is too weak to do so.

In the city, the Rangers slowly awaken from the recent attack. Antonio stands up to find the Barracuda Blade and the injured Deker. Antonio prepares to finish off Deker to prevent him from taking part in Serrator's plan. He controls the urge and leaves the scene. At the Shiba House, as the Rangers discuss the recent events to formulate a plan, Antonio apologies for not taking the opportunity to defeat Deker, despite his friends telling him that he was noble for not attacking Deker when he was unable to defend himself. In the forest, Dayu follows Deker who remembers Serrator's words as he stumbles upon the remains of their old home. The Gap Sensor sounds and Jayden orders the Rangers to split up to find Antonio and deal with the Gap issue. Serrator enjoys his recent victory and awaits Deker to take his place. Deker walks down the road until he runs into Antonio, who tries to reason with him but Deker attacks him. Mike and Kevin arrive in time to protect Antonio. Chasing after Deker as he regains Uramasa from Serrator, the regrouped Rangers are unable to stop him with Serrator in their way. But at the last second, Deker strikes down Serrator instead of the final marker. Deker reveals that he only cares for the sword, not the hatred for humans and tells the Rangers to finish off Serrator. The Rangers morph into action and destroy Serrator with the 5 Disc Octo Cannon and Super Bullzooka. Serrator grows to his Mega Mode and battles the Bull Megazord and LightZord while the Samurai Megazord and Claw Battlezord destroy the Papyrax Serrator summoned. The Rangers form the Samurai Gigazord to finish off Serrator, only for the Symbol Powered Shogun Strike to have no effect against him. On Gold Ranger’s suggestion, Shogun Red summons the Shark Zord and combine with Gigazord into true final combination called Samurai Shark Gigazord to finally destroy Serrator with the Shark Sword Slash. In the forest, Dayu confronts Deker about his decision. Deker responds that he will end his curse on his own terms. As the sun sets the Rangers celebrate their victory.

In a subplot Bulk and Spike attempt to block one of the energy beams in the ground with a giant ball of chewing gum.

This episode was originally scheduled to air October 20, 2012 but was pushed back for the TMNT Premiere.

Mia watches as Jayden trains alone. She notices a monk delivering a message with the Shiba Crest. Mentor Ji gives the message to Jayden, who carefully reads the document. Jayden is worried that his friends will finally learn his secret. Meanwhile on Master Xandred’s Ship, Octoroo is glad to see Dayu returning as he tells her Xandred is still recovering in the Sanzu River. Octoroo summons the Nighlok Fiera to ambush the Red Ranger. He gives her an artifact that is filled with evil flames from the Sanzu River and was designed to take down the leader of the Shiba clan. When she attacks with a group of Moogers to bring the Rangers into the open, Jayden is protected by the others against his wishes. The pain from Fiera’s attacks begin to take their toll on Jayden. With the other Rangers down, Jayden uses the Black Box to finish the fight, barely surviving as he destroys Fiera with the Super Bullzooka. Dayu wonders why the fire didn't consume the head of the Shiba Clan while Octoroo has an idea on why it didn't work. Fiera grows to Mega Mode and Jayden gives Kevin the Black Box. Super Samurai Blue Ranger summons the Claw Armor Megazord. Fiera is too quick for the Claw Armor Megazord. Jayden remains injured on the ground as he sees a blurry vision of a girl walking towards him who reveals a Shiba Morpher. Fiera continues to fire against the Zords. The Lion Folding Zord attacks Fiera on its own as the others realize that Jayden is not the one piloting it. After Fiera is destroyed, the Rangers help Jayden before seeing another Red Ranger who powers down to reveal her true form. Jayden introduces the Rangers to his big sister Lauren, and she is pleased to see her younger brother. Returning to the Shiba House, Mentor Ji tells the story of the Great Battle; of how the previous Rangers fought against Master Xandred and how Jayden's father put his faith in his two children. Lauren was sent into hiding to master the Sealing Symbol while Jayden was chosen to temporarily take her place. Lauren has now mastered the sealing symbol. Lauren takes care of Jayden’s injuries but he plans to leave the team, as he believes the Sealing Power is their only hope to defeat Master Xandred and that there can only be one Red Ranger. Antonio cooks a victory meal for the Rangers and they welcome Lauren to the team. Jayden walks out of the Shiba House after giving the Power Discs to Lauren and tells the Rangers that she is the new leader of the Power Rangers. The Rangers are deeply upset by his decision. Antonio asks Lauren to tell Jayden that they need him, but she remains quiet. Mike questions why Jayden has to leave, but Mentor Ji responds that he can’t be stopped, so Jayden says goodbye to his friends. Kevin wants to join Jayden, who immediately declines. The Rangers watch as he leaves the Shiba House. Later that night, the Rangers miss Jayden and question his departure. Antonio decides go after Jayden, considering himself not a "true samurai". Lauren remains quiet, as she knows she knows that she can never take Jayden's place.

At the docks, Jayden ponders about his departure. Antonio arrives to comfort Jayden, who responds that Antonio must protect Lauren, the new Red Ranger. Antonio leaves for a moment and returns to find Jayden gone. Jayden walks alone in the forest and questions about his true destiny. He runs into Deker, who challenges him to a fight whilst stating that they have something in common: they are both warriors are tormented by fates that they didn't choose. Jayden decides that the world would be a better place without Deker and decides to battle him. At the Shiba House, Mentor Ji tells the Rangers that they should train with Lauren while he searches for Jayden. At the Sanzu River, Octoroo prepares his latest Nighlok: Gigertox, stating this may be their last chance. Dayu is surprised that Octoroo gave half of his life source to Gigertox. Back at the Shiba House, Mia serves lunch and the Rangers try to get to know Lauren. Mia is pleased to see someone loving her cooking. Back in the forest, Mentor Ji watches as Red Ranger faces off against Deker and in an attempt to protect Jayden they both fall down a cliff and land near a stream. Gigertox begins the attack and Antonio fights him alone until the others arrive. Gold Ranger struggles against the powerful Nighlok and he is defeated. Lauren and the other Rangers arrive to the scene to join the fight. At the stream, Mentor Ji reminds Jayden of his childhood and his dedication to the Samurai life but also tries to convince him not to fight Deker but to no avail. Unable to change his mind Mentor Ji leaves Jayden alone after telling him he can do it. The Rangers finally manage to destroy Gigertox who grows into his Megamode form. After defeating him a second time he returns with a third life thanks to Octoroo’s sacrifice. They manage to destroy him with a Symbol Powered Mega Strike. Back at the Shiba House the Rangers look after Antonio and Mentor Ji who tells them about Jayden’s duel against Deker. Jayden and Deker’s duel reaches its climax.

Mike, Mia and Emily leave to find Jayden, while Kevin and Lauren stay behind in case there’s a Nighlok attack. Antonio is told to stay behind as he needs to rest. The epic duel between Jayden and Deker reaches its climax. Sensing his concerns for his friend, Lauren tries to convince Kevin to help the others find Jayden whilst mentioning how she never had a friend. Kevin reminds her that she does now. At the Sanzu River, Octoroo believes that Master Xandred is returning while Dayu senses that Deker is in trouble. By nightfall, a badly injured Jayden manages to deliver what seems to be a mortal blow to Deker. Lauren finally convinces Kevin to find Jayden for her. As Mike, Mia and Emily find Jayden in a ring of fire, Deker stands up again still alive, wanting to continue the fight. The others beg them to stop fighting and are surprised to see Deker talking to himself. In actuality, the spirit of Dayu, in her human form is preventing him from lifting his sword. Deker asks the spirit to leave him alone whilst Jayden takes the opportunity to walk away. Deker charges towards a defenceless Jayden but is saved when Kevin shows up and strikes Deker down. The Rangers help Jayden out of the fire while Deker slowly disintegrates, happy that his curse is finally broken. At the Sanzu River, Octoroo reminds Dayu that she can bring back Master Xandred with her harmonium and Dayu realizes that her dreams are now over with Deker's demise. Later in the forest, Jayden and the Rangers ponder about the recent battle. Jayden thanks his friends for coming to his aid and apologizes for not telling them about Lauren and his secret. As Jayden is about to leave, his friends try to stop him. The Rangers try to convince Jayden that he has and always will be their true leader even if he doesn’t have the sealing symbol. Jayden reminds them it was all a lie. Mike gets upset and tells Jayden to repeat it to his face but Jayden merely looks at his friends with a tear in his eye. Giant Moogers begin to attack the city. Lauren asks Antonio for help while Mentor Ji calls the Rangers. Kevin invites Jayden to the fight who says he will join shortly. The Rangers morph into action and head to the city. Dayu remembers Master Xandred and how he helped to repair the harmonium. She accepts her fate and plays her harmonium to speed up Master Xandred’s reawakening. Mia turns her attention to Dayu and engages in combat with her. Pink Ranger leaps into the air and slices Dayu’s Harmonium causing all of Dayu’s sadness built up over 300 years to be released at once. Dark clouds emit from the Harmonium and the fog clears to reveal Master Xandred.

With Master Xandred back on Earth, the Rangers finally attempt to use the Sealing Symbol to stop him, only to discover that he has a special new defense against it! Xandred had combined Dayu's half human part to him so the sealing symbol won't work on him. Now, they must rise to the challenge and find a new way to defeat him and save the world!

In a climactic battle, the Rangers face off against Master Xandred for the last time. Lauren gives more symbol power to make a second Shiba fire disk. Jayden and the others destroy Master Xandred with the last of their symbol power. Meanwhile, Bulk and Skull are reunited. In the end, Lauren leaves saying she will see Jayden again, Mia goes to cooking school, Kevin goes back to swimming, Antonio goes to a fishing expedition, and Mike and Emily go back to her farm together.
