List of Most Anticipated Characters in the Chainsaw Man Assassins Arc

1. Quanxi

Quanxi is called the First Devil Hunter because she’s unbelievably fast that hunters can’t even see her move. She travels with four fiend girlfriends and wants human rights and education for them instead of money. She’s both kind and deadly. When she pulls an arrow from her eye and turns into the Bow Hybrid with crossbow arms, she becomes really dangerous. She plays a very prominent role in the Chainsaw Man Assassins Arc.

2. Santa Claus

Forget everything you think you know about Santa. This main villain is utter nightmare fuel: a hive-mind of creepy, empty dolls run by one unknown person. Touch someone? They become a mindless doll. And when those dolls touch others? More dolls. It’s a zombie apocalypse, more or less. Eating the flesh of the Darkness Devil, Santa becomes an unkillable monster and spreads pain through all their dolls. The final showdown in the Chainsaw Man Assassins Arc is going to be epic.

3. Aldo

Aldo is an assassin as scared as the audience is. While his siblings are making death jokes, Aldo is throwing up his guts at the scene of crimes, trying to convince himself that he’s immortal. His Skin Devil's contract allows him to put on dead people’s faces. Complications arise when he starts to feel guilty about using his victims’ faces. And yes, his survival strategies and mindset throughout the Chainsaw Man Assassins Arc make him (somehow) relatable in a way that makes him actually kind of likable for a hitman.

4. Tolka

Tolka appears to be a minor character, but is featured prominently in the Chainsaw Man Assassins Arc. There’s a young Soviet Devil Hunter and Santa Claus apprentice, who was brought up to think murder is no big thing. Loyal to Santa, he stabs Denji to help her retire peacefully. Immediately after completing his task, Santa transforms him into a doll, leaving his body to be possessed by what was left of the Doll Devil in Hell.

5. The Darkness Devil

Okay, everything changes when this thing shows up. The Darkness Devil is a Primal Fear: a Devil so powerful it's literally never died. Its design is pure horror, with multiple emaciated corpses forming a body with a pteranodon head. It doesn't talk, doesn't negotiate. It just appeared and instantly severed everyone's arms with invisible force in the Chainsaw Man Assassins Arc. Watching it casually demolish Quanxi, Aki, and everyone else in seconds will be MAPPA's most terrifying animation yet.

---

6. Cosmo

She has a naked brain, one eye hanging down, and she says "Halloween" and nothing else, with a smile. Sounds quirky and harmless. But Cosmo has the power to make your brain attempt to process everything in the universe simultaneously, which is what it feels like to have your grey matter smashed into pieces. Your whole life after this will be you drooling and whispering "Halloween" till you die. She tricks Santa Claus in the Chainsaw Man Assassins Arc into keeping her locked in a Halloween state of knowledge loop for all eternity. Terrifying and poetic.

---

7. Hirofumi Yoshida

Yoshida is a high schooler who's also a bodyguard for Denji in the Chainsaw Man Assassins Arc. His contract with the Octopus Devil gives him tentacles that bind enemies, create smokescreens, and swallow people whole. He's calm, playful, and ruthlessly efficient. Watch him execute enemies without breaking his cool demeanor. He even holds his own against Quanxi. Plus, he sticks around for Part 2, so this introduction matters big time.

---

8. Kusakabe

One of Makima's handpicked elite bodyguards, Kusakabe, takes his job seriously and gets annoyed when Denji disrespects him in the Chainsaw Man Assassins Arc. His Stone Devil contract is super effective: stand in a circle, blow through your fingers, and enemies turn to stone. Perfect for dealing with doll armies. But the arc shows how brutal things get when the Darkness Devil appears in Hell and instantly destroys the Stone Devil, killing Kusakabe without effort.

---

9. Tamaoki

Another elite bodyguard who's less flashy but seriously smart. When Power crashes into a disguised enemy in the Chainsaw Man Assassins Arc, Tamaoki instantly recognizes the Skin Devil contract and warns everyone about two more brothers lurking nearby. His quick thinking saves the team during chaos. Like Kusakabe, he charges at the Darkness Devil in Hell and gets sliced apart instantly. His death hammers home that regular Devil Hunters simply can't compete with Primal Fears anymore.

---

10. Doll Devil

This devil never shows its true form in the Chainsaw Man Assassins Arc, but its presence is everywhere. Its contract with Santa creates dolls through touch that spread like a virus, with each new doll able to create more. After Santa sends everyone to Hell, it literally possesses Tolka's corpse to negotiate with the Darkness Devil. The dolls can transform their arms into blades and fake human emotions on command. This contract is the backbone of Santa's entire terrifying operation.

Conclusion

The Chainsaw Man Assassins Arc is going to hit different. These character introductions will change how you see the entire series, especially when the Darkness Devil shows there are threats way beyond anyone's league. MAPPA has their work cut out for them, but if they nail these designs and fights, we're in for something special.
