Season 1Season 2 - Season 3 - Season 4 - Season 5

The fifth and final season of the 2012 Nickelodeon television series, titled "Tales of the Teenage Mutant Ninja Turtles" aired on Nickelodeon (Episodes 1-10, 18-20) and Nicktoons (Episodes 11-13 and 14-17) from March 19, 2017 to November 12, 2017, distributing a shorter, sparser set of 20 episodes in a collection of seven story arcs, unlike previous seasons, which spans 26 episodes and usually follows a single plot-line. It mainly revolves around the Turtles facing various supernatural threats and other characters after arriving in alternate dimensions and/or time travelling, and largely dealt with the fallout and the Turtles taking on the few stragglers remaining from the Kraang and Shredder’s empire.[1][2][3][4][5][6][7][8][9][10]

Tales of the Teenage Mutant Ninja Turtles depicts seven distinct story arcs, showing the last several adventures the Turtles embark in the months following Splinter's passing, such as the Turtles revisited by familiar allies/comrades from previous seasons to battle familiar villains (also from previous seasons) who have cheated their deaths and returned for revenge, as well as encounter and befriend some new allies (especially when transported to alternate dimensions and/or time travel through history) and team up to defeat new arch-enemies. This season also includes a flashback set during the Turtles' early youth in New York City following their mutation and explores glimpses of possible, hypothetical futures. Throughout the season, fans can expect to see both new and familiar friends and enemies as each story arc unfolds. The series concluded on November 12, 2017, with the final 3-episode 68-minute long story arc titled "Wanted: Bebop & Rocksteady".

This is the only season where the Turtles are left to fend for themselves and are guided by Leonardo (following Splinter's death), although his spirit continues to watch over his family from the afterlife and occasionally visits them (mostly Leo) to offer some advice and suggestions (excluding "Lone Rat and Cubs" and the "Raphael: Mutant Apocalypse" arc).

Story Arcs and Plot

Tales from the Beyond - The Kavaxas Saga (Shredder resurrection): Episodes 1-4

After successfully avenging the death of their beloved sensei and father Splinter (thanks to the demise of the Super-Shredder at the hands of Leonardo), the four Turtles, April O'Neil, Casey Jones, Leatherhead and Karai have all coped with his loss and re-adjusted to their new daily lives as they wonder about what lies ahead, knowing the Foot isn't over yet and there are still enemies out there. Nonetheless, Splinter's spirit continues to watch over his family from the skies of heaven and occasionally visits Leo to offer him advice. As the heroes prepare for their next imminent threat on the road ahead (knowing that Splinter is still there with them, in spirit), Leonardo succeeds Splinter as the team's new sensei, which makes his life even more burdensome, stressful and tazing more than ever due to a very heavy burden of stressful responsibility he now has weighing down on his shoulders as Karai decides to be in charge of and rework the Foot Clan, having become the rightful heiress to the clan.

However, though the Turtles had believed that they have defeated their old enemies, they soon discover that a new evil is on the rise. The Foot Clan has been reborn as an underground cult led by Tiger Claw, who plans to resurrect the Super Shredder with the aid of the mighty demodragon named Kavaxas, who is summoned by the Scroll of the Demodragon and a controlling amulet called the Seal of the Ancients. Upon demonstrating his ability to revive the dead with Rahzar, who fell in an underwater battle against Leatherhead, Kavaxas states that he will need Shredder's mutated heart through which new life can flow and the Kuro Kabuto that contains Shredder's mental energies.

When Karai searches for the Kuro Kabuto, having become the rightful heiress of the Foot Clan, her former sensei, Hattori Tatsu, also seeks rightful ownership by hunting the Shredder's legendary helmet himself. Unfortunately, Tiger Claw and his lackeys are also in search of the helmet, as it is one of the essential items required for Kavaxas to return the Super Shredder to life. This creates a feud between Tatsu and Tiger Claw, who are both in possession of the helmet. Upon Rahzar and Tiger Claw reclaiming the Kuro Kabuto after Kavaxas drained the soul out of Shredder's former right-hand man Hattori Tatsu, Kavaxas states that they will need the Shredder's heart for the resurrection to occur.

Donatello's grudge against Don Vizioso endangers the Turtles' newest and next mission: To retrieve the heart of the Super Shredder, which is in the possession of Don Vizioso himself. However, despite Leo's best efforts to keep Donnie in line, their mission fails, and the Foot Clan obtains the Shredder's heart and the resurrection is set in motion.

With the aid of Karai and Leatherhead, the Turtles, April and Casey must defeat Kavaxas and prevent him from destroying the world with his army of the undead. Kavaxas successfully revives Shredder as an undead zombie horror, who breaks the Seal of the Ancients, freeing Kavaxas and allowing him to raise the spirits of the Netherworld to rule both worlds. As ghosts take over the city, Kavaxas (who has now unleashed his true potential) jeopardizes the future. All of this goes against what Tiger Claw planned, so he sides with the Turtles to defeat the undead Zombie Shredder and Kavaxas. While the ghost of Splinter helps Donnie, April, Casey and Raph, who are fighting on the surface, Michelangelo (with the help of Leatherhead) managed to use gum to stick the Seal of the Ancients back together, enabling him to control Kavaxas. He orders and coerces the demodragon to open the portal to the Netherworld and undo all of his damages to restore peace and order. As Tiger Claw watches alongside Leo and Karai, Zombie Shredder drags Kavaxas back to the Netherworld. Now aware of Zombie Shredder and Kavaxas' sinister, ulterior motives, Tiger Claw ends his feud and makes peace with the Turtles before departing (possibly for Japan). The spirit of Splinter revisits the team once more. He embraces Karai, looks fondly at Leonardo, amazed to see how far his son has come before sending his good wishes to the rest of the team (Raph, Mikey, Donnie, April, Casey and Leatherhead). His spirit soars towards the skies of heaven, fading away.

With Zombie Shredder, Rahzar, and Kavaxas defeated (sent back to suffer in the Netherworld), in addition to Tiger Claw making peace with the Turtles, our heroes, before destroying the seal, gaze at a beautiful sunset as they prepare for (and wonder about what lies on) the road ahead, knowing that Splinter is still with them, in spirit.

Alien Tales - When Worlds Collide Saga: Episodes 5-6 

Some time later, the Turtles' romantic plans to hang out with their love interests are put on hold when Raphael's Salamandrian girlfriend Mona Lisa (Lieutenant Y'Gythgba) and her superior, Sal Commander G'Throkka (after being gone since Season 4), arrive on Earth, touch down on a New York City rooftop, revisiting the Turtles and their allies, asking for their aid in finding and destroying the Newtralizer (his real name is K'Vathrak, an escaped outlaw), whom after being gone since Season 2, had just received unlimited power in search of the Utroms to destroy them, disrupting peace between the Ultron High Council (with the Earth Protection Force) and Earth. As it was later revealed that the Newtralizer was working with Lord Dregg, who had cheated his death from the Triceratons and Kraang (returning from Season 4) while swearing his revenge on the Turtles where he launched his original invasion on the Salamandrian homeworld of Salamandria, putting Mona Lisa and Sal Commander in a goose chase with the Newtralizer, all the way in his new living command ship, revealing in the fact that he could now get his revenge on both the Turtles and the Salamandrians by taking over Earth and using the human population for his own malicious intent in the form of Vreen eggs. As a result, Raphael must convince Bishop (who commands the Ultroms and the Earth Protection Force) to join forces with the two Salamandrians. After the demise of the Newtralizer and Lord Dregg, Mona Lisa ultimately chooses to stay on Earth.

Note: This is a two-part special episode.

Samurai Tales - The Samurai Turtles Saga: Episodes 7-9 

In an alternate dimension inhabited by anthropomorphic animals in Feudal Japan, a lone rabbit samurai Ronin and master swordsman named Miyamoto Usagi has been given a task to protect a childish and bratty pug child named Kintaro, who is deemed as the "Golden Child" of the Sky Buddha and holds hidden super strength. The gray wolf-demon and evil wizard Jei, who is Usagi's long-time sworn enemy, transported the Turtles into his realm, planning to use them as henchmen to murder Usagi and abduct Kintaro to Jei in addition to casting an evil enchantment on the Turtles by posing as a blind and crippled wolf. The Turtles (under Jei's evil spell) almost succeeded, but Usagi overpowered them, and with one blow to the head, restored them back to their normal senses. With nowhere else to go, the Turtles, after learning about Usagi's story, allied themselves with him to escort Kintaro to the Temple-Palace of the Sky Buddha atop a tall mountain before Jei prepared for his endgame. Along the way, Usagi leads the Turtles through a haunted forest where they encountered magically mischievous and dangerous creatures and spirits whilst tensions boiled between Usagi and Leonardo, but they eventually buried the hatchet.

Tales from the Past - Lone Rat and Cubs: Episode 10

A flashback episode shows how Splinter and the four young Turtles as babies found their underground lair while being pursued by the Kraang. After his victory, Splinter was given a second chance at fatherhood, naming the infant Turtles after his favorite Italian artists of the Renaissance.

Note: This is a flashback set during the Turtles' childhood youth and before the series premiere, Rise of the Turtles, Part 1, when they turn 15.

Tales from the Future - Raphael: Mutant Apocalypse Saga: Episodes 11-13 

  • The Wasteland Warrior (Part 1 of 3) 
  • The Impossible Desert (Part 2 of 3) 
  • Carmageddon! (Conclusion) Three episodes of the series are set outside the rest of the series' time frame and are typically presented as a standalone television movie, Raphael: Mutant Apocalypse

Fifty years later in an alternate dimensional and hypothetical, but desolate, dystopian future that has been caused by a Mutagen Bomb, terraforming all of Manhattan (and possibly much of the Earth) into a post-apocalyptic desert wasteland, wiping out the entire human population, an old and weathered Raphael, accompanied by Donatello, who is now an android robot (due to his original body being destroyed but his thoughts and memories restored into this new form), scour a desolate wasteland that was once their home of New York City as they battle road gangs. They encounter a meerkat named Mira, who is being hunted by Verminator Rex and his Honey Badger Ravagers, and who has a map tattooed on her arm that leads to the Oasis. The trio set out to find a hermit called "the Holy Chalupa", who turned out to be an elderly Michelangelo with Ice Cream Kitty and Chompy Picasso (who is now full-grown), but they were later attacked by Verminator Rex and Imperius Reptilicus. The warlord Maximus Kong pursues them in his mobile fortress, and in a shocking revelation is shown to be Leonardo himself, driven mad with rage from a secondary mutation. Raphael manages to break through his brother's deranged and maniacal insanity and restore him to his old self, and the four brothers travel to the Oasis.

The camera pans up to the sky, where the spirit of the four Turtles (in their teenage years) and the spirit of Splinter are all reunited at the skies of heaven. A shot shows them taking a black-and-white picture together, followed by Leonardo holding a picket sign dedicated to the creators of the Teenage Mutant Ninja Turtles franchise, Peter Laird and Kevin Eastman.

Note: This story arc was originally intended to be the "true" ending (production-wise, it technically is the series finale in terms of production order), even though it doesn't fit into the canon timeline (i.e. Renet, who is from the future), and for very dubious reasons on Ciro Nieli's intentions. According to the press release for the final DVD, it's officially "another alternate dimension". Ciro Nieli admitted the "Mutant Apocalypse" three-parter, which features the Turtles failing to stop a Mutagen bomb in a flashback and the heavily implied deaths of almost all of the supporting cast, was done so that nobody could continue this series after it was finished. On the other hand, other Nickelodeon crew members themselves disagreed with that assessment, with Nickelodeon calling the story an alternate dimension/universe, rendering the arc non-canon. According to the press release for the final DVD, it's officially "another alternate dimension" according to Nickelodeon.

Additional notes: These episodes originally aired on Nicktoons on September 22, 2017, during the middle of Season 5. However, the these episodes were aired in Disney XD Japan as the last episodes in July 7, 2019, and then the remaining two episodes aired on September 14, 2019.[11]

 Monstrous Tales - Monsters vs. Mutants Saga: Episodes 14-17[12]

Reverting back to present-day New York City, during Halloween night, the Turtles must postpone their Halloween celebration tour when they discover that strange monsters are infesting New York. They revisited by their time-travelling ally and Mikey's crush from the future, Renet. They are also reunited with their sworn enemy, Savanti Romero, who, after supposedly being defeated in Season 3, had also cheated his death and vengefully schemes to turn all of New York City into a monster-filled dystopia. The Turtles and Renet escape to the safety of the rooftops after April and Casey (who discover an unholy epidemic has overrun Manhattan, turning it into a dystopian zombie city filled with strange, real-life monsters, vampires, zombies and werewolves) turn into vampires.

In a desperate race against time to save thousands of lives (all to save New York City, mankind, and themselves), Renet and the Turtles' fun, but terrifying quest to stop their monster foes (trying to battle demon Savanti Romero as he travels through history assembling a team of mankind's worst Universal monsters) sends them back in time to four stops: Ancient Egypt, where Savanti recruits a dangerously powerful mummy pharaoh with evil magic, 1300 Transylvania where he successfully awakens and recruits the vampire lord Count Dracula (who returns Savanti the favor by turning Vulko, a Romanian traveller Renet and the Turtles ally with, into a vampire-werewolf and also bites Raphael, who also turns into an evil bloodthirsty vampire), and 1818 Germany with Dr. Victor Frankenstein. After the Turtles help Dr. Frankenstein resurrect a corpse, a major battle ensues, resulting in the Turtles successfully re-capturing Raph, but Savanti successfully lures Frankenstein's monster with his monster tribe. Upon returning to present-day New York City, the Turtles and Renet discover (much to their horror) that the city has been infested with even more monsters, vampires, zombies and werewolves now than ever before, realizing that their previous failures to defeat Savanti when they had the chance has made the situation even worse. They have one last chance to have order restored, but when the Turtles' lair is discovered and trashed by Savanti's monster tribe, who turns Donnie into a vampire in the chaos of the brawl, things become even worse. Casey turns into a vampire, along with April, Donatello and Raphael, until he returns to normal, due to Mikey defeating Dracula.

Notes: These episodes also aired on Nicktoons from September 27th, until October 11, 2017.

Crossover Tales - TMNT Series Finale - Wanted: Bebop & Rocksteady Saga: Episodes 18-20

The 3-episode series finale also takes place in present-day New York City as another crossover story arc as a three parter, several weeks following the Monstrous Tales saga, where the Turtles are once again revisited by their '87 counterparts from the 1987-1996 series reality (after originally encountering them during Season 4) due to their versions of the 1987 Shredder and Krang entering the 2012 realm and recruiting the 2012 versions of Bebop and Rocksteady (who are jobless and broke), as they had accidentally left their versions of the 1987 Bebop and Rocksteady behind. Since everything is still going in favor in the 1987 Shredder and Kraang's plans, the foursome is plotting to conquer the Earths of both the 1987 and 2012 realities with a fully powered 1987 Technodrome. While the Turtles and their allies fight off a horde of Foot Soldiers from the 1987–1996 series reality and the 2012 Rock Soldiers, the 2012 Bebop and Rocksteady discover the 1987 Shredder and Krang's plans to destroy the Earth and choose to become heroes in order to save the planet.

Note: This is the actual series finale in terms of Nickelodeon broadcast (Nov. 12, 2017). The Nickelodeon crew members aired "Raphael: Mutant Apocalypse" in the middle of Season 5 on Nicktoons, Sept. 22, 2017, even though it was originally intended to be the series finale, before declaring it another alternate dimension according to a press release for the DVD. This was followed by the 4-episode Monsters vs. Mutants story arc, also broadcasted on Nicktoons less than a week later (reverting back to present-day NYC infested by monsters). The 1987 crossover arc aired as the actual final 67-minute, three-episode series finale on Nickelodeon instead.


Main Characters/Protagonists

Friends and Allies



On July 10, 2015, Nickelodeon ordered a fifth season of Teenage Mutant Ninja Turtles. The first four episodes were released to DVD on March 21, 2017, two days after the season 5 TV premiere on Nickelodeon.

On March 2, 2017, Nickelodeon and Viacom renewed the series for a fifth and final season, retitling it as "Tales of the Teenage Mutant Ninja Turtles", and its opening titles were changed, featuring a brand new opening theme with instrumental music instead of a rap, and that Season 5 would broadcast a shorter, sparser 20 episodes instead of the usual 26 (like the previous four seasons), consisting of several story arcs instead of following one single plot-line. It was also announced by Nickelodeon that the series would conclude after five seasons and that Season 5 will be the show's last. When asked about the possibility of more seasons, it was noted that while Ciro Nieli originally planned on finishing the series after five seasons, they weren't opposed to doing more seasons, even if it would mean they would have to modify the series plan. No such modification occurred, and the series ended at five.

"The Wasteland Warrior, "The Impossible Desert", and "Carmageddon!" are typically presented as a television movie, "Raphael: Mutant Apocalypse". Although these episodes were not the last to air, and not officially considered canon by Nickelodeon, they were the last episodes produced.[13] In an interview, executive producer Ciro Nieli revealed that he intended for these episodes to be the series finale in order to prevent any alteration of the timeline that he and the rest of the crew had built[14], despite the episodes' contradictions to previously established canon (most notably Renet's description of the future from the Season 3 episode "Turtles in Time"). However, the production team and crew from Nickelodeon chose to air those episodes on Nicktoons in the middle of the season, and officially issued a statement on their social media websites, announcing that "Wanted: Bebop and Rocksteady" would be the official series finale and canon ending on Nick. instead.[15] On threads from the franchise Twitter account (which is run by Nickelodeon), they indicated that "Raphael: Mutant Apocalypse" is non-canon and more of a hypothetical "what if..." future arc.[16][17] and a press release for the DVD refers to the special as "another dimension"[18]

While Ciro intended "Mutant Apocalypse" to be the series finale, other staff members have a different opinion. One of the writers considers the end of Season 4 and the Kavaxas arc to be the finale. Character designer Felipe Smith refers to its setting as "In this reality", while the TMNT franchise Twitter account (which is run by Nickelodeon) calls it "A tale from beyond," indicating that it has been rendered non-canon. They reinforced this by referring to it as "another dimension" and a "special" in an official press release for the final DVD, cementing its status. Brandon Auman halfway flip-flopped by declaring that it was up to the audience whether it was an alternate universe and that it could be seen as one, allowing everyone to be happy.

Episodes 11–17 originally aired over Nicktoons, instead of Nickelodeon. On 11 January 2018, the season became available at Hulu.
