What is Lelouch Lamperouge’s IQ?
No official IQ score; 180–200 is a fan guess. The record is a rebellion, a world coalition and the Zero Requiem.
Lelouch’s IQ has no official source as of November 2026: Code Geass gives Lelouch Lamperouge, also called Lelouch vi Britannia, no score, and the 180–200 online is a fan guess. This site estimates 175–195, inferred from what he does: he leads a rebellion as Zero, builds a world coalition and completes the Zero Requiem.
Lelouch Lamperouge’s estimated IQ
- In episode 2 (October 13, 2006) he takes command of a resistance cell against Viceroy Clovis la Britannia’s army, forces Britannia to deploy its experimental Lancelot Knightmare, and then confronts Clovis alone, reminding him of the chess games they played as children.
- At Narita (episodes 10 and 11, December 2006) the Black Knights hit Viceroy Cornelia li Britannia’s army with a landslide and corner Cornelia, who is saved only when Suzaku arrives in the Lancelot.
- Runs two identities side by side through the first season, ordinary Ashford Academy student and masked Zero, until Suzaku shoots off Zero’s mask in episode 25 (July 29, 2007).
- In R2 (2008), after his memories are restored, he rebuilds the Black Knights, forges the multinational United Federation of Nations, takes the Britannian throne and, two months later, completes the Zero Requiem.
- Wikipedia describes a genius-level intellect, and Otakuzine ranked him among the most intelligent anime characters for his battlefield achievements, which it compared with his chess. Both are critical judgments of a character, not measurements.
No canon number exists. This range is an editorial estimate based on demonstrated feats, offered for comparison with the site’s other fictional profiles, not a fact the source material states. His results also lean on a supernatural power the plot hands him. His range overlaps those of Light Yagami (170–190) and L Lawliet (178–195), so the gaps between the three are smaller than the method can resolve.

What an IQ of 175–195 actually means
Set the claim aside for a moment. If someone genuinely scored in this range, here is what that would represent.
Average is 100 by construction, and about two-thirds of people fall between 85 and 115. Take the test to place your own score on this scale.
| Score range | Classification | Share of people | What it indicates |
|---|---|---|---|
| 85 – 114 | Average | ~68% | The range most people fall into. |
| 115 – 129 | Above average | ~13.6% | Roughly one person in seven. |
| 130 – 144 | Gifted | ~2% | The threshold most high-IQ societies use. |
| Above 144 | Highly gifted | ~0.1% | Figures above this range are extrapolated from the curve rather than measured. |
Percentages are approximate and describe a normal distribution. The same number means different things on tests with different standard deviations.
Thirty questions gives you a measured position on this exact scale — your score, your percentile and the ability breakdown behind it.
Find out in 30 minutes →Who Lelouch Lamperouge is
Is Lelouch Lamperouge the same person as Lelouch vi Britannia? Yes. Lelouch vi Britannia is his birth name as the Eleventh Prince of the Britannian Imperial Family, seventeenth in line for the throne, and Lelouch Lamperouge is the alias he lives under as a student at Ashford Academy.
Code Geass: Lelouch of the Rebellion premiered on MBS on October 5, 2006 (1:25 a.m. on October 6, Japan time) from studio Sunrise, directed by Gorō Taniguchi and written by Ichirō Ōkouchi, with original character designs by Clamp. A second season, R2, ran from April to September 2008. The setting is an alternate history in which Britannia has conquered Japan and renamed it Area 11.
C.C., an immortal “witch,” grants Lelouch Geass, the power of absolute obedience. He uses it to lead the Black Knights under the masked identity Zero while living as an ordinary student. His closest friend and principal foil is Suzaku Kururugi, a Britannian soldier who wants to change the empire from within.
Lelouch’s stated aim is a peaceful world for his younger sister Nunnally, who was left blind and disabled by the attack that killed their mother, Marianne. The two were sent to Japan as political hostages after he questioned their father, Emperor Charles zi Britannia, about it.
The series ends with the Zero Requiem. After Lelouch takes the Britannian throne, Suzaku, in the guise of Zero, kills him two months later, and Nunnally succeeds him as Empress, as Wikipedia’s plot summary records. The film Code Geass: Lelouch of the Re;surrection, set after the Zero Requiem, opened in Japanese theaters on February 9, 2019. The staff have said it is Lelouch’s last appearance in the franchise.

Lelouch Lamperouge: the documented record
The estimate above rests on this record. Every entry here is a matter of public fact, which is more than can be said for the number itself.

Where the 180–200 figure came from
Following a claim back to its first appearance is the part almost nobody does — and it is what most people are actually asking.
Where does the 180–200 IQ for Lelouch come from? From fan writing, not from the series. An InfoHeist article of December 27, 2025 estimates Lelouch’s IQ from his problem-solving, strategic thinking and emotional intelligence, concludes that 180–200 “would not be unreasonable,” and calls the estimate “purely speculative.”
EpicStream (January 27, 2023) says there is “no official account” of his IQ and that some fans claim it could be over 200, which it judges likely an overstatement. How numbers like these spread is the subject of where celebrity IQ numbers come from.
The 180–200 band also fails on arithmetic. On the usual scale, with a mean of 100 and a standard deviation of 15, a score of 180 is 5.3 standard deviations above average and 200 is 6.7.
Standard tests have no items that far out, which is the subject of the IQ ceiling effect, and what the word “genius” means for real test-takers is set out in what a genius IQ level is. This page’s own range sits above that ceiling too, which is why it is labeled a rating of the portrayal.
What the story does show is specific. In episode 2 (October 13, 2006), right after C.C. grants him Geass in episode 1, Lelouch takes command of a resistance cell against Viceroy Clovis la Britannia’s army and then confronts Clovis face to face. At Narita (December 15 and 22, 2006), a landslide takes out much of Viceroy Cornelia li Britannia’s army before Suzaku rescues her.
In R2 (April to September 2008) he rebuilds the Black Knights, forges the United Federation of Nations, takes the Britannian throne and, two months later, completes the Zero Requiem. The record includes failures too: in the first season’s finale he abandons the Black Knights’ battle when Nunnally is taken, and EpicStream notes that his grades at school are only average because he rarely attends class.
Chess is the one skill the series ties to him directly, and it comes with no rating. Wikipedia’s list of Code Geass characters says his classmate Rivalz drives him around on a motorbike as the stake in their chess bets, that Clovis kept losing to him in childhood games, and that Schneizel is the only person he could not beat at chess as a child.
EpicStream calls him a “chess prodigy.” None of this is a rating: an Elo number comes from results against rated opponents, and how real chess ratings relate to IQ scores is covered in chess ratings and IQ.
Is Lelouch smarter than Light Yagami or L? No source settles it, and the numbers overlap. This site rates Lelouch 175–195, Light Yagami 170–190 and L Lawliet 178–195, a spread smaller than the method can resolve. The Light and L profiles each document a ten-point intelligence rating from the Death Note guidebook. The sources behind this profile give Lelouch no equivalent, so his rating rests on feats alone.
Wikipedia notes that IGN compared him with Light because of the double life and questionable methods of the two characters, and EpicStream argues that Lelouch used his intelligence more consistently because Light was eventually found out, an opinion rather than a measurement. Professor Moriarty carries the same 175–195 range on a different kind of evidence, a scholarly record rather than a rebellion; more minds rated the same way are listed under other fictional characters we have checked.

States there is no official account of Lelouch’s IQ, that fan claims of over 200 are likely an overstatement, that his grades are average because of low attendance, that he can command any person only once, and that he is a chess prodigy. Opinion piece.
Source of the circulating 180–200: it says a score of 180–200 would not be unreasonable while calling it purely speculative, and gives no test, episode or creator statement.
No IQ score for Lelouch appears in the Wikipedia articles above, and EpicStream reports no official account of one. The absence is the finding.

The sources behind our estimate
The figures that circulate for Lelouch Lamperouge, what we were able to confirm, and where the two diverge.
The 180–200 range appears in an InfoHeist article of December 27, 2025, which calls it “purely speculative”; EpicStream (January 27, 2023) says some fans claim more than 200. Neither names a test, an interview or a source in the series behind its number.
No IQ score for Lelouch appears in the Wikipedia articles on the character, the series or its episodes, and EpicStream reports no “official account” of one. InfoHeist offers 180–200 only as “purely speculative.” What exists instead is description: Wikipedia credits him with a genius-level intellect, Otakuzine ranked him among the most intelligent anime characters for his battlefield achievements. The plot shows a rebellion, a world coalition and the Zero Requiem.
The circulating band, 180–200, sits slightly above this site’s 175–195 range, and neither comes from a test: both are inferred from what Lelouch does. On a scale with a mean of 100 and a standard deviation of 15, 180 is 5.3 standard deviations above average and 200 is 6.7, past the roughly 160 where standard tests stop separating people reliably. This site’s upper end is above that point too, so read it as a rating of the portrayal.

Lelouch Lamperouge — frequently asked
What is Lelouch’s IQ?
Lelouch Lamperouge, also called Lelouch vi Britannia, has no official IQ score. EpicStream (January 27, 2023) reports no official account of his IQ, and the 180–200 that circulates is a fan guess. This site’s estimated IQ for him is 175–195, a character-analysis range inferred from what he does in Code Geass, not a score from the series.
What is Lelouch vi Britannia’s IQ?
Lelouch vi Britannia is Lelouch Lamperouge’s birth name, so the answer is the same: no IQ is published. Wikipedia’s character list calls him the Eleventh Prince of Britannia, seventeenth in line for the throne. This site’s estimate for him is 175–195, on a scale with a mean of 100 and a standard deviation of 15.
How much IQ does Lelouch have?
None is stated: Code Geass gives Lelouch no IQ. The 180–200 figure appears in an InfoHeist article of December 27, 2025, which calls it “purely speculative” and bases it on his problem-solving and strategic thinking, while EpicStream (January 27, 2023) says some fans claim more than 200. Neither names a test, an interview or a source in the series.
How smart is Lelouch?
In the story, very smart: Otakuzine ranked him among the most intelligent anime characters for his battlefield achievements, which it compared with his chess. He leads the Black Knights as Zero, builds the United Federation of Nations in R2 and completes the Zero Requiem, although EpicStream notes his school grades are only average because he rarely attends class.
Is Lelouch a genius?
Within the story, yes: Wikipedia describes his genius-level intellect, and EpicStream says he is “nothing short of a genius.” Those are descriptions of a character, not test results, and no source gives him an IQ score, so the label cannot be converted into a number.
Who is smarter, Light or Lelouch?
No source settles it. EpicStream argues Lelouch used his intelligence better because Light was eventually found out, but that is an opinion. This site rates Lelouch 175–195, Light Yagami 170–190 and L Lawliet 178–195, a gap smaller than the method can resolve.
What is Lelouch’s chess rating?
Lelouch has no chess rating, so no one can say what it would be; Code Geass gives him no Elo number. Wikipedia’s character list says Rivalz drives him around as the stake in their chess bets, Clovis kept losing to him as a child, and Schneizel is the only person he could not beat. EpicStream calls him a “chess prodigy.”
What is Lelouch’s Geass, and can he use it on the same person twice?
Geass is the power of absolute obedience that C.C. gives Lelouch, and according to EpicStream he can command any person only once. This site rates the planning built around the power, not the power itself.
What was Lelouch’s goal, and what is the Zero Requiem?
Lelouch sets out to destroy the Britannian Empire and build a peaceful world for his sister Nunnally. The Zero Requiem is the plan in which he takes the throne and, two months later, is killed by Suzaku in the guise of Zero; Wikipedia describes the two men orchestrating his death to bring peace, and Nunnally succeeds him as Empress.
