26 Teenage Mutant Ninja Turtles Villains, Ranked

26. Pizza Monsters
First appearance: 1987 cartoon (Season 2, Episode 6)
It’s not that the Pizza Monsters are all that intimidating or memorable. What puts them on the list, albeit at the end, is they were clearly ripoffs of the xenomorphs from the 1979 film Alien.
There have been more dastardly things to come from Dimension X, but rarely have they been so clearly taken from another franchise.

25. Za-Naron
First appearance: 2012 cartoon (Season 4, Episode 22)
Za-Naron only lasted a single episode, but in it, this entity controlled April O’Neil and turned her against the turtles. It’s a moment no turtle was ready for.

24. Newtralizer
First appearance: 2012 cartoon (Season 1, Episode 24)
The Newtralizer, a member of the Salamandarian race, is a bounty hunter who brought trouble to both the turtles and the Kraang during the 2012 animated series. Fun fact: Newtralizer was voiced by Danny Trejo.

23. Stone Generals
First appearance: TMNT (2007)
The chief antagonists of the 2007 animated film, these ancient and massive stone warriors, the siblings of Max Winters, are summoned to help take over the world. Interestingly, they don’t appear in any other incarnation of Teenage Mutant Ninja Turtles.

22. Jei
First appearance: Usagi Yojimbo #10
Though this character was originally created for the Usagi Yojimbo line of comic books, Jei ultimately crossed over into the Ninja Turtles universe in the 2012 animated series–along with Usagi. With his dark magic abilities and expert ninja skills, he was a force to be reckoned with.

21. General Traag
First appearance: 1987 cartoon (Season 1, Episode 4)
Traag, the leader of the rock soldiers, is one of the earliest villains from the original Ninja Turtles animated series. He appeared in 12 episodes, and then made a re-appearance in the 2012 cartoon.

20. Purple Dragons
First appearance: Teenage Mutant Ninja Turtles #1
This street gang appeared in the first ever TMNT comic book in 1984, giving the turtles their first real fight. The mutants killed most of them.

19. Agent Bishop
First appearance: 2003 cartoon (Season 3, Episode 3)
As a government agent who prevents alien invasions, Bishop was a thorn in the side of both the Turtles and the Utrom during the 2003 cartoon. It was revealed in the 2012 series that he, himself, was actually an Utrom.

18. Tiger Claw
First appearance: 2012 cartoon (Season 2, Episode 13)
The sibling of Alopex — another TMNT villain — this mutant tiger assassin was experimented on by the Kraang. You have to feel some sympathy for a villain who became evil thanks to the actions of someone else.

17. Triceratons
First appearance: Fugitoid #1
Initially introduced in a comic book miniseries before the Turtles existed, this race of alien dinosaurs found prominence in the 1987, 2003, and 2012 cartoons. They’re one of the few villains to actually have a win over the turtles in the original animated series.

16. Slash
First appearance: 1987 cartoon (Episode 83)
Slash — originally, the pet of Shredder henchman Bebop — became something of a demented version of a Ninja Turtle after getting mutated.
In the 2012 series, he was originally Raphael’s pet turtle.

15. Danny Pennington
First appearance: Teenage Mutant Ninja Turtles (1990)
Danny is an awkward teenager looking for love and acceptance, finding it in a ninja street gang. He made the right choice in the end but caused a lot of damage along the way: April’s home burned to the ground, the turtles lost their sewer dwelling and Splinter was tortured.

14. Leatherhead
First appearance: Tales of the Teenage Mutant Ninja Turtles #6
Leatherhead is one of the classic turtle villains introduced in the original comics that has managed to survive the test of time, appearing in several graphic novels, video games, and cartoons. Though he was originally a Cajun-accented menace to the turtles, the 2012 animated series recast him as one of their allies.
He works really well on both sides.

13. Rat King
First appearance: Tales of the Teenage Mutant Ninja Turtles #4
As with Leatherhead, Rat King dates back to the original comics. This maniac dwells in the sewers, controlling an army of rats in his attempts to destroy the Turtles.
Image: Lionsgate
12. Master Tatsu
First appearance: Teenage Mutant Ninja Turtles (1990)
Master Tatsu never gets a fair shake in the original Turtles movie. He’s second-in-command of the Foot Clan, and Shredder treats him like just another underling.
His introduction in the 2012 cartoon went a long way in building the character’s legacy as a madman.
Image: New Line
11. Foot Elite
First appearance: Leonardo #1
These are the best the Foot Clan has to offer. Trained by Shredder himself, the Foot Elite serve as a bodyguards who swear their lives to him alone. In the 2012 animated series, they are reimagined as enhanced robots.

10. Tokka and Rahzar
First appearance: Teenage Mutant Ninja Turtles II: The Secret of the Ooze
At the time this movie was released, Tokka and Rahzar seemed like little more than cheap replacements for Bebop and Rocksteady. This massive mutated wolf and snapping turtle deserve some respect, though. While they may have the personalities of babies, these babies nearly kill the turtles in combat.
Image: New Line
9. Alopex
First appearance: Raphael #1
Alopex is one of the best modern TMNT villains. She wasn’t introduced until IDW’s micro-series of comics in 2011, but has since gone on to become a major force in the franchise thanks to her role in the 2012 cartoon. As a mutant ninja herself, this fox was a fierce foe of the turtles — and her brother, Tiger Claw.

8. Hun
First appearance: 2003 cartoon (Season 1, Episode3)
This leader of the Purple Dragons gang was created specifically for the 2003 animated series, becoming one of its primary antagonists. His size, ninja skills, and street gang army made him a true danger to the turtles.
In the 2012 animated series, he was reimagined as the Chinese American foe of Casey Jones.
Image: Nickelodeon
7. Foot Clan
First appearance: Teenage Mutant Ninja Turtles #1
Wherever the Shredder is, the Foot Clan is at his side. His loyal ninja army has been portrayed in a number of ways, from lost teenagers looking for a home in the original movie to robots in the 1987 cartoon.
They have always been a constant presence in the franchise, providing the turtles with more battles than anyone else.
Image: New Line
6. Karai
First appearance: Teenage Mutant Ninja Turtles #53
Karai’s history is complicated. She’s been portrayed as both the adopted and biological daughter of the Shredder. She’s also been played as the biological daughter of Splinter. She was even the love interest of Leonardo at one point.
The constants are her incredible fighting skills and her high-ranking spot within the Foot Clan.
Image: Nickelodeon
5. Baxter Stockman
First appearance: Teenage Mutant Ninja Turtles #2
This mad scientist has been making life miserable for the turtles since day one, largely thanks to his Mousers — small killing robots that target sewer rats like Splinter. In certain incarnations of the Turtles franchise, he becomes a mutated fly.

4. The producers of Ninja Turtles: The Next Mutation
First appearance: Ninja Turtles: The Next Mutation (Season 1, Episode 1)
These villains might be the absolute worst — because they exist in real life. This short-lived, live-action show tried (but failed) to emulate the Power Rangers, even crossing over with Power Rangers in Space at one point.
The turtle costumes look cheap, the series introduces a new female turtle that doesn’t mesh well with the crew, and the primary villain is a lizard monster that looks like it’s made out of rubber. The Next Mutation is a stain on the brand that will hopefully be forgotten someday.
Image: Fox
3. Bebop and Rocksteady
First appearance: 1987 cartoon (Season 1, Episode 1)
Though Shredder’s primary henchmen are shown to be incompetent at… everything, they’re featured in most episodes of the original cartoon, along with the 2012 series, comics, and 2014’s Teenage Mutant Ninja Turtles: Out of the Shadows.
Image: Lionsgate
2. Krang
First appearance: 1987 cartoon (Season 1, Episode 2)
Krang is based on the brain-like Utrom alien race, which have appeared in multiple TMNT properties over the years. Hailing from Dimension X, Krang is Shredder’s micromanager in the first animated series.
Image: Lionsgate
1. Shredder
First appearance: Teenage Mutant Ninja Turtles #1
Shredder’s history with the franchise has changed a few times over the years, but his deep connection to Hamato Yoshi — the man that became Splinter — remains intact. Their feud dates back to their time in Japan, and carries on now with Shredder heading the Foot Clan and Splinter training his turtle sons.
