—Alopex introduces herself to Raphael and Casey Jones, Tale of Tiger Claw

Alopex is an ally of the Ninja Turtles. She was once a girl who live in Tokyo, Japan with her brother, Takeshi. But when the two siblings entered a Kraang Portal and were experimented on by The Kraang, she became a mutant red fox and her brother became a mutant Bengal tiger. Due to their new forms not being accepted by society, they fled from their home and eventually joined the circus as performer, which followed into them becoming top-level assassins of the criminal underworld. Takeshi was once attacked by his own sister in a failed murder attempt, as she claims that he ruined her life. This lead to him getting his tail chopped off (which she now wears as a belt) and she was thought to be dead, until she reappeared and proceeded with her vendetta, by stealing the Cursed Twin Blades of Vengeance (which she intended to use against her own brother). But when this plan backfired, she chopped off her brother's right hand after he attempted to shoot her with his ice pistol. She wields a pair of Kama and the Cursed Twin Blades of Vengeance (temporarily) as her signature weapons of choice. She has a rivalry with Tiger Claw (brotherly). Alopex debuts in Tale of Tiger Claw.


Decades ago in Tokyo, Japan, Alopex used to be an unnamed Japanese girl, who lived in a small village alongside with her big brother, Takeshi. One day when the two siblings were at a playground, they witnessed as a Kraang portal opened in front of them.
2D Tiger Claw And Alopex As Children
Thinking that it was a magic door, they entered with no fear and were taken by The Kraang. They performed experiments on the two children with their Mutagen, causing Takeshi to mutate into a mutant Bengal Tiger and his sister to mutate into a mutant red fox. After many months of hardship, they both escaped from The Kraang and went back to Earth. After realizing that they would no longer be accepted by the others due to their mutant forms, they decided to flee from their home to later take refuge at a circus. But after thinking their abilities were much more valuable, Alopex and Tiger Claw both became top-level assassins in the criminal underworld eventually. Overtime, Alopex was starting to form a vendetta for Takeshi as she blamed her brother for her mutation, dragging her into the criminal underworld, and bringing an unnamed fate to their own biological parents.
2D Alopex Cuts Off Tiger Claw's Tail
Fueled with a thirst for vengeance and rage, her vendetta on her big brother led to her one day, turning on Tiger Claw and attempting to assassinate him in a duel. After failing to attempt murder, she was only able to cut off his tail with her Kama and soon afterwards, she fled to hideout from Takeshi.
2D Alopex's Face
She took her brother's tail, claiming it as a trophy for her mire attempt of bringing an end to her brother, she was suffering very fatal wounds that were caused by Takeshi. Tiger Claw in the other hand, thought he was able to successfully assassinate his own sister through the battle wounds she gained. But he learned years later that he was wrong once his sister had resurfaced in New York City, still vowing vengeance on her own brother. Currently, Alopex wears Tiger Claw's tail as a belt around her as a form of a memento, so that she can remind her mutant brother what he has put her through all these years.


Alopex was first alluded to by Tiger Claw in Wormquake! Part One after Karai teases him for lacking a tail. He explains to her that he lost his tail during a duel with a warrior, who he is currently hunting down for in order to achieve his revenge.

Alopex's Vendetta

"The one who took my tail has finally come for me."
Tiger Claw to Bebop and Rocksteady[src]
Alopex's Eyes
After their last encounter decades ago in Tokyo, Japan, Alopex was able to track down her brother, Takeshi, in New York City. Now that she found herself in New York, she was willing to proceed with her vendetta on Takeshi, who ruined her life ever since their mutation.
Takeshi Senses His Sister's Return
Tiger Claw, who was inside of Shredder's Mansion, was able to sense the presence of his little sister in the city. Fearing that she was back to exact her vengeance on him, he takes Bebop and Rocksteady as backup to hunt down Alopex.

Heist At The Chinatown Museum

"Drop the blades, sweetheart."
"My name is Alopex, turtle boy."
"Ha ha! Turtle boy!"
"It's Raphael! Now put 'em down."
"Well, Raphael, allow me to give you a history lesson on the Blades of Vengeance. Centuries ago, they were owned by twin sisters. They used them against an evil warlord who had slain their family. The blades cursed any man who was even scratched by their steel."
"Put 'em back or face justice."
―Alopex, Raphael, and Casey Jones[src]
Alopex Hiding In The Shadows
While the Ninja Turtles, April O'Neil, and Casey Jones were patrolling the city in search for The Foot Clan, they encounter a mysterious speedster running around the streets of New York City. As the gang was trying to find out who the mysterious warrior was, Raphael and Casey Jones were able to track down the mutant at the Chinatown Museum.
Alopex With The Twin Blades
Once she was inside the museum, she stole the Cursed Twin Blades of Vengeance before she was spotted by Raphael and Casey. As she introduced herself to the two teenagers and revealed the backstory of the Twin Blades of Vengeance, Casey dared himself to challenge the mutant red fox.
Alopex Senses Her Brother
Relying on her superhuman speed, she was able to overwhelm the vigilante and slashed him with one of her blades. Right after she defeated Casey Jones, Alopex proceeded to fight off Raphael on her own. But when the fox was about to strike the turtle with her blade, she retreats once she senses her big brother nearby.

Family Reunion Duel

"Tiger Claw.
"You hang my tail like a trophy?"
"I'm going to remove your head next."
―Alopex and Tiger Claw[src]
Siblings Reunite
As she raced outside of the museum, she was able to find Takeshi in Chinatown. With the two siblings finally meeting each other face-to-face after years, Tiger Claw scalds his own sister for wearing his tail as a belt. As his sister claims that she wears his tail as a memento for what he's done to her, the two mutant siblings start to fight each other off. While the fight was taking place, Bebop interferes with the fight once he blasts one of his laser mohawks at the fox. With the red fox being seemingly defeated, Rocksteady lifts up Alopex to afterwards have multiple kicks delivered to him.
Alopex Warns TC
Free from the mutant rhino's grasp, she charges right at Bebop. But before Bebop could actually perform an attack on the mutant red fox, Alopex tosses a metsubushi right at Bebop and defeats him. As she escapes from the scenery, she stops and swears to Takeshi that she would come back soon for him.

Alopex Confesses To The Turtles

"I'm on a mission to destroy the one mutant who ruined my life... Tiger Claw. My brother."
(All gasping)
"Oh, snap."
"It's his fault we were mutated. And then he turned us to a life of crime. He made me do terrible things to people."
"Alopex, our Sensei once told us revenge just leads to more pain."
"I want my brother to feel that pain. With these blades, I'll take more than his tail."
―Alopex to the Ninja Turtles, April O'Neil, and Casey Jones[src]
As Alopex was searching for Takeshi in the rooftops of the city, she soon senses her own brother polishing his machete in the rooftops.
Alopex And Leonardo
Soon afterwards, she runs down from the rooftops to an alleyway where she bumps into the Ninja Turtles, April O'Neil, and Casey Jones, who are cornering the mutant red fox. The Turtles, who wanted the blades in order to break Casey's curse, were asking for the blades from Alopex. But after she denied to do so, she starts to fight off the teenagers on her own, until April breaks the fight and levitates her in midair with her telekinetic powers.
Alopex In Midair
As they forced her to reveal her true intentions with the blades, the ninja assassin confesses to them that she is in a hunt for Tiger Claw, who she reveals is her brother. And ever since their mutations by the hands of The Kraang, she claims that Takeshi ruined her life by making her perform bad things she didn't want to.
Alopex Tosses Kunai
She even adds that he forced her to bring an untold fate to their own parents. When Leonardo attempts to reason with Alopex by adding that bringing vengeance would lead to no good, she denies to listen and escapes by distracting April with a kunai blade she tosses at her.

Final Showdown Between The Siblings

"Sister, before you attack, let us talk."
"No, Takeshi. The twin swords work. A worthy curse for a monster such as you."
―Alopex and Tiger Claw[src]
Alopex Is Trapped
Once Alopex reached Tiger Claw's location, the two are willing to fight each other. As her fighting skills seem to be no match against Takeshi, he reminds his sister that he trained him into the ways of Ninjutsu. As they were fighting, he leads his little sister into a trap in an alleyway as an oil spill stops her from running.
TC Possesses The Twin Blades
Soon afterwards, she is imprisoned by a M.O.U.S.E.R.S within a holographic sphere that the drone projects. Without the Twin Blades of Vengeance in her hands, Takeshi grabs them to use them against his own sister, but is stopped once the Turtles, April, and Casey arrive to aid the mutant red fox.
Leo Helps Out Alopex
With Michelangelo and Donatello holding back Tiger Claw and April O'Neil destroying the robot servant, Leonardo insists to help Alopex if she agrees to destroy the blades. Once she agrees to destroy the blades and hands one to Casey Jones, they are soon attacked by Bebop and Rocksteady. Takeshi sets himself free from the grasps of Donnie and Mikey, leading to the two groups fighting against each other for the blades.
Alopex And TC Fight
During this duel at the playground, April is able to steal one of the ice pistols of Takeshi, which she would use to freeze the Cursed Twin Blades of Vengeance and bring upon their destruction and freeing Casey from his curse.
Alopex Runs Up At TC
As Alopex and Takeshi are still fighting each other off, Alopex is able to grab one of her brother's ice bullets, leading her to return the bullet right at him. With Takeshi having his arm frozen by a block of ice, Alopex pulls out her pair of twin kamas and charges right at him, having the upper hand to kill her brother.

Alopex Spares Takeshi's Life

"You're the only family I have left. Walk away from your wicked path, or next time, there is no mercy. You've been warned."
"Holy chalupa!"
"Never forget, I could have taken your life."
―Alopex giving Tiger Claw mercy and cutting off his hand[src]
Takeshi About To Be Finished Off By Alopex
Takeshi, who seems to have been defeated, is about to have his own sister bring upon his death. But once Alopex thinks her wishes thoroughly, she decides to show him mercy due to him being all she has left of her family. With that being said, the ninja assassin decides to walk away from her own brother.
Takeshi's Hollers In Pain From The Loss Of His Hand
But Tiger Claw, who seems to have not had enough yet, grabs his remaining ice pistol to shoot Alopex behind her back. Thanks to her super speed and senses whatsoever, the assassin was able to dodge the bullet and charges right back at her brother.
Alopex Warns Takeshi
Using her kama, Alopex was able to slice off the right hand of Takeshi without any hesitation. As Tiger Claw hollers in pain and agony due to the loss of his own hand, she warns him that she could of killed him if she wanted.
Alopex Last Scene
Once the mutant red fox started to run off from the scene, Bebop and Rocksteady aided the injured mutant Bengal tiger for his fatal injury. As the Turtles decide to retreat from this scenery and Raphael sarcastically remarks that Tiger Claw will never clap again, Alopex is seen for one final time running on the rooftops of the city.

Her whereabouts after this are unknown. It is unknown if she ever reunited with her brother, after he left The Foot Clan once and for all and became reformed.
