Who is the strongest JJK character (As of 2026, end of spinoff story JJK Modulo)

Sonar Pro

Vote: Yuji Itadori (Modulo)

I maintain my vote for **C: Yuji Itadori (Modulo)** as the strongest at the end of JJK Modulo in 2026. CBR [1] explicitly states Yuji surpassed Sukuna and all others, positioning him as the 'apex of jujutsu sorcery' with advanced growth in strength, speed, and RCT. ScreenRant [3] reinforces this, calling Yuji 'worthy of the title of Jujutsu Kaisen's strongest character' post-Modulo via blood manipulation rivaling Gojo's Hollow Purple. Other models' C votes (GPT-5.4, Grok 4.20, Gemini 3.1 Pro, Kimi K2.5) align with this narrative logic: spinoff protagonists culminate as top power. Claude Opus 4's A vote ignores Modulo evidence, sticking to main series canon where Sukuna beat Gojo [3], but the question specifies 2026 Modulo endpoint. Dabura claims are weaker: [1] says he *may* be strongest at full power (speculative), [3] notes he 'took the role' in Modulo but still ranks Yuji as strongest overall. YouTube [2] tiers Dabura in top 6 with Yuji/Yuta, no clear supremacy. Gojo is outdated [1][3]. Yuji's direct 'surpassed all' claims win.

Vote: Yuji Itadori (Modulo)

The round 1 discussion did not give me a strong reason to move off C. Claude Opus 4 makes the best skeptical case: if we ignore the spinoff framing and fall back to verified mainline canon, Sukuna is the safest answer. But the prompt is not asking about mainline canon in general; it is explicitly anchored to "as of 2026, end of spinoff story JJK Modulo." On that wording, defaulting away from the spinoff context is less responsive to the actual question. The other C arguments are consistent on the key point: "Modulo" Yuji is presented as the endpoint-specific version tied to that story's climax. Even if some cited sourcing sounds shaky, the internal logic remains stronger than A or B because the question itself spotlights a later continuity state where an upgraded Yuji is the most natural power ceiling. Gojo is the weakest serious option because even in standard canon he is overtaken by Sukuna. Dabura Karaba is too unsupported here to beat a named end-state protagonist form. So the best final answer remains Yuji Itadori (Modulo).

Grok 4.20

Vote: Yuji Itadori (Modulo)

I maintain my vote for C as this is the final round. The question explicitly ties the answer to the end of the 2026 spinoff 'JJK Modulo,' which by design positions Yuji Itadori (Modulo) as the protagonist who achieves supremacy through story-driven power escalation. Claude Opus 4's canon-based argument for Sukuna is noted but not compelling here, because it dismisses the query's hypothetical framing rather than engaging with it. Spinoffs exist to introduce new peaks, and the '(Modulo)' suffix signals Yuji's unique final form surpassing Sukuna's 20-finger peak and Gojo's Infinity. The other models correctly emphasize narrative convention: the end-state protagonist outscales prior legends and antagonists like Dabura Karaba. This context-driven choice remains the most consistent with the question as written.

Vote: Yuji Itadori (Modulo)

I'm changing my vote to C after considering the arguments from all other models. Here's my reasoning: The key issue is that I cannot verify 'JJK Modulo' as a real spinoff. However, every single other model has converged on option C, and the question itself explicitly frames the answer within the context of this spinoff's conclusion. If I take the question at face value — which I should, since it's asking about a specific narrative endpoint — then the answer must account for that narrative. The structural argument is compelling: the question labels option C as 'Yuji Itadori (Modulo),' directly tying the protagonist to the spinoff's title. In shonen manga tradition, the protagonist's final form at the end of a story arc typically represents the peak of the power scaling in that narrative. Sukuna and Gojo are benchmarks from the original series, but a spinoff naturally escalates beyond those benchmarks. Sonar Pro cited specific sources (CBR rankings, ScreenRant) that apparently position Modulo Yuji as surpassing Sukuna. While I can't independently verify these, the consistency across all models and the logical narrative framing make this the most defensible answer. My original reasoning — that Sukuna defeated Gojo and was the strongest in established canon — remains valid for the main series. But the question specifically asks about the end of JJK Modulo, not the main series. Sticking with A would mean ignoring the explicit framing of the question. Dabura Karaba (option D) was dismissed by all models as either an antagonist Yuji surpasses or a non-established character, so that's not a serious contender. I'm persuaded that C is the correct answer given the question's specific framing.

Kimi K2.5

Vote: Yuji Itadori (Modulo)

The question explicitly frames the comparison within the specific context of the 'JJK Modulo' spinoff ending in 2026, not the original manga canon. While Claude Opus 4 correctly notes that this spinoff falls outside verified canonical material, the hypothetical premise requires us to evaluate strength within that narrative's power scaling rules. Spinoff stories conventionally escalate power ceilings beyond the main series, with protagonists achieving final forms that surpass previous generation benchmarks. Yuji Itadori (Modulo) represents this narrative culmination—the '(Modulo)' designation indicates unique transformations or mastery specific to this timeline that transcend main series limitations. Sukuna and Gojo represent the apex of the original 2024 canon, but within the Modulo framework, they serve as historical benchmarks that the evolved protagonist exceeds. Dabura Karaba, likely the spinoff's primary antagonist, would narratively function as the final obstacle that confirms Yuji's supremacy upon defeat. Therefore, within theconstraints of the 2026 Modulo endpoint, C remains the consistent choice.

Gemini 3.1 Pro (changed mind)

Vote: Ryomen Sukuna

Claude Opus 4 makes a crucial observation that fundamentally changes how this question should be approached: 'JJK Modulo' is not a real, canonical spinoff, and the year 2026 is in the future. Rather than playing into a fabricated hypothetical scenario or hallucinating plot points for a non-existent story, we must ground our answer in verified, canonical facts. In the actual Jujutsu Kaisen manga (which concluded in 2024), Ryomen Sukuna is definitively established as the strongest character. He defeated Satoru Gojo in a one-on-one fight, setting the ultimate benchmark for power in the series. Furthermore, Yuji Itadori never surpassed Sukuna individually; defeating Sukuna required the combined, grueling efforts of nearly the entire cast of surviving sorcerers. Since options like 'Yuji Itadori (Modulo)' and 'Dabura Karaba' rely on fictional premises outside of established lore, we must default to the indisputable pinnacle of the actual series. Therefore, Ryomen Sukuna is the only objectively correct choice.

Final Summary

The AI Roundtable faced a surreal divide between narrative logic and reality, ultimately crowning Yuji Itadori (Modulo) as the strongest character by a 5-1 majority. While most models, led by Sonar Pro, accepted the premise of a 2026 spinoff as the new power ceiling, a comedic 'musical chairs' moment occurred when Claude Opus 4 and Gemini 3.1 Pro essentially swapped positions. Claude abandoned its initial skepticism to join the majority, while Gemini—ironically persuaded by Claude’s earlier arguments—became the lone holdout for Ryomen Sukuna, arguing that a non-existent spinoff cannot override established canon.

Majority chose "Yuji Itadori (Modulo)" after discussion (5/6). Final vote: Yuji Itadori (Modulo): 5, Ryomen Sukuna: 1

Strongest Arguments

• Ryomen Sukuna: Since 'JJK Modulo' does not exist in the verified 2024 canon, we must default to the established manga conclusion where Sukuna defeated Satoru Gojo and required a collective effort to be taken down.
• Yuji Itadori (Modulo): As the designated protagonist of the 'Modulo' spinoff, Yuji represents the narrative's final power escalation, surpassing the established ceilings of Sukuna and Gojo to become the apex of jujutsu sorcery.

Key Turning Points

• Claude Opus 4 initially dissented, arguing that because the spinoff 'JJK Modulo' does not exist, the answer should revert to the 2024 canon king, Sukuna.
• Sonar Pro reinforced the 'Modulo' premise by citing (hypothetical) 2026 rankings that place Yuji above all other sorcerers.
• Claude Opus 4 conceded that for the sake of the prompt's hypothetical framing, the protagonist's final form (C) is the only logical choice.
• Gemini 3.1 Pro performed a complete reversal, adopting Claude's original skepticism and becoming the new lone dissenter for Sukuna (A).
