Ryomen Sukuna is established in Jujutsu Kaisen lore as the undisputed King of Curses. He is a four-armed, two-faced terror from the Heian Era who treats human lives like kitchen scraps and expands his "Malevolent Shrine" to level entire city blocks. However, in the chaotic corners of the internet, this terrifying deity has been stripped of his intimidation, his teeth, and his dignity. Enter Thukuna, or "One Tooth Sukuna," a viral phenomenon that turned the manga’s most dangerous antagonist into a lisping, single-toothed laughingstock.

This shift from a "natural disaster" to a "toothless toddler" represents one of the most fascinating examples of modern anime meme culture. It captures the specific brand of insanity that defines the Jujutsu Kaisen community, often referred to as "Lobotomy Kaisen." By examining the roots, the mechanics, and the cultural impact of Thukuna, we can understand how a simple Photoshop edit evolved into a dominant internet trend.

What Is the One Tooth Sukuna Meme?

The "One Tooth Sukuna" meme consists of edited images and videos featuring Ryomen Sukuna where his rows of sharp, menacing teeth are removed, leaving only one or two prominent front teeth. The visual change is jarring; the character’s usual predatory grin is replaced by a look that oscillates between infantile and elderly.

The name "Thukuna" is an onomatopoeic representation of a lisp. In meme videos, Sukuna’s voice lines are often re-recorded or edited to replace all "s" sounds with "th" sounds. Instead of declaring himself the King of Curses, he becomes the "King of Curtheth." Instead of expanding his "Malevolent Shrine," he summons his "Malevolent Thrine." The contrast between the high-stakes, dark fantasy setting of Gege Akutami’s work and the absurdity of a powerful demon struggling with basic phonetics is the primary engine of the meme’s humor.

Where Did the Thukuna Meme Originate?

Like many viral anime trends, Thukuna’s origins are traced back to short-form video platforms and image-sharing boards where fan creativity thrives on irony.

The TikTok Explosion

The earliest documented instances of the "One Tooth Sukuna" visual edit began appearing in late 2023. While fans had been making "low-quality" or "cursed" edits of characters for years, the specific one-tooth iteration gained significant traction on TikTok around October 2023. Users like @satorugojodayo were among the first to showcase these photoshops, often set to high-energy or intentionally annoying music to enhance the surrealism.

The Spread to Reddit and X

By early 2024, the meme migrated to subreddits like r/Jujutsufolk, a community known for its high-octane "shitposting" and relentless meme production during manga breaks. Here, the meme evolved from a simple visual joke into a linguistic one. The "Th" phonetic replacement became a standard way for fans to mock Sukuna’s arrogance, especially during his grueling, multi-chapter battles where he seemed untouchable in the canon material.

The "Lobotomy Kaisen" Context

To understand why Thukuna exploded, one must understand the state of the Jujutsu Kaisen fandom at the time. Following major plot twists—specifically the events involving Satoru Gojo in chapter 236—the community entered a state of collective psychological breakdown. The term "Lobotomy Kaisen" was coined to describe the nonsensical, repetitive, and increasingly unhinged memes produced by fans waiting for new chapters. Thukuna was a perfect fit for this environment: it was nonsensical, easy to replicate, and served as a form of "coping" by humanizing or ridiculing an otherwise invincible villain.

The Anatomy of a Thukuna Edit

Creating a Thukuna meme requires a specific set of visual and auditory cues that have become standardized within the community.

1. The Visual Edit

The most common base image is Sukuna’s smug face, often from his fight against Jogo or Mahoraga in the Shibuya Incident arc. Editors use tools like Photoshop or mobile editing apps to clone the skin of the gums or lips over the teeth. Leaving exactly one tooth in the center of the upper jaw is the "golden rule" for maximum comedic effect.

2. The Lisp (The "Th" Factor)

The linguistic component is what elevated Thukuna from a static image to a multimedia powerhouse. Fans realized that the name "Sukuna" is phonetically perfect for a lisp parody.

  • Sukuna → Thukuna
  • Special Grade → Thpethial Grade
  • Satoru Gojo → Thatoru Gojo
  • Dismantle and Cleave → Dithmantle and Cleave

3. The Soundtrack

Many Thukuna videos use specific background tracks that signify a "brain rot" meme. High-pitched, sped-up versions of popular songs or nursery rhyme melodies (like "A Ram Sam Sam") are frequently used to underscore the infantile nature of the edit.

Why Do We Find One Tooth Sukuna Funny?

From a psychological perspective, the humor of Thukuna relies on Incongruity Theory. This theory suggests that humor arises when there is a mismatch between our expectations and reality.

The Subversion of Power

Sukuna is defined by his overwhelming power and his absolute lack of empathy. He is the ultimate "cool" villain. By giving him a single tooth and a lisp, the meme strips away the "cool" factor. It is a form of digital iconoclasm. Seeing the being who defeated the world's strongest sorcerer struggle to say the word "Mississippi" provides a cathartic release for fans who are frustrated by his dominance in the story.

The Relatability of Failure

There is something inherently humanizing about a speech impediment or a missing tooth. By projecting these "human" flaws onto a thousand-year-old curse, the meme makes Sukuna relatable in the worst possible way. He isn't just a villain anymore; he's the annoying kid in class who thinks he's a genius but can't pronounce his own name.

The Communal Language

Memes like Thukuna act as a shibboleth—a way for members of a group to identify one another. Using the term "Thukuna" in a comment section immediately signals that you are part of the deep Jujutsu Kaisen fandom. It builds a sense of community through shared irony.

How the Thukuna Meme Impacted the Community

The reach of One Tooth Sukuna extended far beyond simple image macros. It influenced how fans interacted with the series and each other.

The Rise of Thukuna AI Chatbots

Platforms like Shapes.inc and Character.ai saw a surge in "Stupid Thukuna" or "One Tooth Sukuna" bots. These AI personas are programmed to respond exclusively with a lisp. Fans spent hours interacting with these bots, trying to get "Thukuna" to say complex words or engaging in mock battles where the AI would threaten them with a "Malevolent Thrine." This interactive element kept the meme alive much longer than a standard image-based trend.

Fan Art and Animation

Talented artists began drawing high-quality versions of Thukuna. Instead of the gritty, dark art style of the anime, they would use bright, pastel colors or "chibi" styles, further leaning into the parody. Animators on YouTube and TikTok created short clips of Sukuna trying to perform his "World Cutting Slash" but accidentally biting his tongue because of the single tooth.

The "Hater" Culture

The Thukuna meme became a weapon in the "agenda wars" of the JJK fandom. Fans of Satoru Gojo or Yuji Itadori would use Thukuna edits to mock Sukuna fans whenever the villain faced a setback in the manga. It became a visual shorthand for saying, "This is your goat?"

Comparing Thukuna to Canon Sukuna Forms

To truly appreciate the absurdity of One Tooth Sukuna, we must look at what he is supposed to look like according to the source material.

Form Key Characteristics The "Thukuna" Version
Heian Era Sukuna Four arms, two mouths, towering height, multiple eyes. One giant tooth in each mouth, four arms flailing helplessly.
Yuji-Sukuna Lean, muscular, sinister tattoos, sharp predatory grin. A "cutie patootie" look with a single central tooth.
Megumi-Sukuna Brooding, tactical, utilizing the Ten Shadows technique. Summoning "Mahoraga" but calling it "Mahoratha."
Complete Reincarnation The pinnacle of jujutsu perfection. The pinnacle of "brain rot" perfection.

Reference materials often rank Sukuna's forms based on their power (like the 15-finger Shibuya form or the 20-finger Heian form). In the world of memes, however, Thukuna is the "Zero-Finger" form—a version so weak and ridiculous that he becomes invincible in the realm of comedy.

How to Make a One Tooth Sukuna Meme

For those looking to join the "Lobotomy Kaisen" ranks, the process is relatively straightforward. The barrier to entry is low, which is why the meme spread so quickly.

  1. Select a Menacing Frame: Find a screenshot of Sukuna looking particularly arrogant or evil. The more serious he looks, the funnier the edit will be.
  2. Tooth Removal: Use a "healing" or "content-aware fill" brush to remove all teeth.
  3. The Lone Survivor: Draw or paste back one single, square tooth in the very center of the upper lip.
  4. Add the Caption: Use a font like Impact or the standard TikTok text. Ensure you use the "Th" spelling. Example: "I will dithmantle the world."
  5. Voiceover (Optional): If making a video, use a high-pitched voice filter and speak with an exaggerated lisp.

Is the Thukuna Meme Still Relevant?

While the peak of Thukuna virality occurred in early 2024, the meme has left a lasting mark on the anime community. It paved the way for other "toothless" edits of popular characters, from Solo Leveling's Sung Jin-woo to One Piece's Luffy.

More importantly, it established a template for how fans deal with long-running series that feature overpowered antagonists. When a villain becomes so strong that they feel oppressive to the narrative, the community naturally gravitates toward memes that "nerf" them in the most humiliating ways possible. Thukuna is the gold standard for this type of fan response.

Conclusion

The "One Tooth Sukuna" or "Thukuna" meme is more than just a silly Photoshop job; it is a testament to the creativity and collective humor of the Jujutsu Kaisen fandom. It turned the "King of Curses" into a lisping parody, providing a much-needed sense of levity in a series known for its tragedy and darkness. Whether he is summoning his "Malevolent Thrine" or struggling to pronounce "Special Grade," Thukuna remains a beloved icon of the "Lobotomy Kaisen" era, proving that even the most terrifying villains aren't safe from the internet's relentless pursuit of the absurd.
