Jeremie! *scoffs* That's very reassuring! It's nice to know the closest thing to Bruce Willis is coming to the rescue!

–Sissi speaking about Jeremie in Holiday in the Fog

Jeremie Belpois (also spelled Jeremy Belpois or with an accented spelling Jérémie Belpois, pronounced as "Jerr-mee Bell-Pwah") is one of the main protagonists of Code Lyoko, and a Lyoko Warrior. Jeremie is 11 years old at the start of the series, but with the intellectual and scientific, gifted and talented mind of someone far beyond his years. He acts as the group's guide and programmer for Lyoko, since he is the only one that is most capable of operating the Supercomputer, behind Aelita. It is also Jeremie's discovery of the Supercomputer that commences the group's quest to materialize Aelita into the real world, which is revealed in X.A.N.A. Awakens. He's noble, but sometimes has a short temper. He is Aelita's love interest.


Jeremie is first introduced as part of Odd and Ulrich's class. He succeeds in every class, except Gym (as shown throughout the series, most notably in Maiden Voyage) and Italian (as mentioned in Attack of the Zombies), and is considered a gifted student by a lot of teachers and the school psychologist, who decides that he needs to go to a special school for gifted children (as seen in Plagued). He is often considered, and sometimes for good reasons, the teachers’ pet, and therefore he had a few friends before befriending the rest of the Lyoko Warriors. Jealously looked upon by Herb, one of Sissi's group members, Jeremie is perceived as a boring and inaccessible intellectual by the other school kids, except his group of friends. Despite this, however, Jeremie's character is portrayed as a kind and compassionate, somewhat naïve individual, and his friends look up to his brains.

Wearing simple clothes and big glasses, his clothes reflect his modest and discreet character. Nevertheless, Jeremie is nothing of a stereotype because, other than his academic performance, he has a really well-asserted personality. His character can be compared to Yumi's, due to their stubbornness and devotion to studies.

An introvert, Jeremie spends most of his time in front of his computer screen, under the friendly glance of Einstein, the portrait of whom hangs over his bed. He spends most of the series programming, and the viewer will often see him going without sleep at night, all to achieve the goal of freeing Aelita and destroying X.A.N.A. once and for all. If not working, he is often conversing with Aelita, for whom he develops particular feelings as they spend hours talking, with Jeremie enlightening her about the "real world" to prepare her for her future life on Earth.


Jeremie, being the stereotypical nerd, in what he has in book smarts, he lacks in common knowledge. He sometimes tends to forget that there are others that are not as smart as him, making comments on the simplicity of the supercomputer to the other Lyoko Warriors who couldn't possibly understand it without detailed guidance (with the exception of Aelita and Laura). He can also be seen as a hot-head at times, as well as a workaholic, with defeating X.A.N.A. constantly on his mind, causing him to sometimes snap on the other warriors. He also appears to be very mature, despite being the youngest.


Jeremie is a blonde-haired bespectacled boy with a fair complexion. He usually dons black lensed glasses.

For the first three seasons, Jeremie wears a blue long-sleeved shirt and shoes, brown pants and no socks. In Season 4, his shirt became red, his pants became moss green with blue stripes and his shoes became navy blue with gray soles. In Evolution, he dons plaid shirts with the sleeves either short or rolled up his forearm, grey jeans and tan shoes.

Abilities and Equipment

Jeremie has various tools that aid him in his differing exploits, the most notable of which is his laptop, which he carries with him all the time in case his Superscan program detects a X.A.N.A. attack. It is one of his primary technological ports, the other two being the computer in his dorm and the interface at the lab. In Evolution, he has also seen utilizing it by programming it into a smartphone app, alerting him when there is an attack, and can also apparently use it to communicate with the Lyoko Warriors when they are virtualized. Despite being seemingly defenseless, Jeremie often has the equipment necessary to fight off the latest attack. He is known for making good use of the tools around his present location, such as in Plagued, where he discovered the X.A.N.A.-possessed rats' weakness: light; by using a common flashlight. He is also known to have an interest in building robots, as seen in Swarming Attack, Killer Music, and The Robots. Most of them are composed of various high-tech devices. Where he gets the money to buy such expensive tools is unknown.

Since most of the things Jeremie uses are immediately used and not tested, some of them inevitably fail. For example, his bee-distracting robot in Swarming Attack ran out of batteries, resulting in the near-death of Ulrich (who was saved by Yumi). His attempt to create a monster to keep X.A.N.A.'s monsters at bay, while Aelita deactivated towers in Marabounta, also had disastrous results: almost killing Aelita on Lyoko. Also, in Nobody in Particular, his program to virtualize people directly into Sector Five is used on Ulrich, separating his body and mind, allowing X.A.N.A. to take control of his body and use it to attack the Core of Lyoko. His materialization program for Aelita also had various attempts, most of which had failed, until Code: Earth.

Jeremie has shown his computing skills, by developing a wide variety of different codes and programs, that have both helped and hindered the success of the Lyoko Warriors. In Tip-Top Shape, Jeremie began to experiment with towers by activating them. When he does, the aura around the tower turns green. Jeremie has only managed to activate towers three times, each of which was attacked by X.A.N.A.. Also, in Tip-Top Shape, X.A.N.A. took over the tower that Jeremie was using to pixelize Odd. In Revelation, X.A.N.A. attempted to take over the tower that Jeremie and Aelita were using to decode Franz Hopper's diary. This attack, however, was thwarted by Franz Hopper himself.

In Season 4, Jeremie was getting better at protecting his towers from X.A.N.A.'s influence, since he has full knowledge of Lyoko thanks to the data sent by Franz Hopper used to recreate the virtual world. In Double Take, Jeremie activated a tower to create a clone of himself. Since it couldn't directly control it, X.A.N.A. had to use William to attack and possess the tower, so it could control the clone, but the tower was deactivated by Aelita, and after a return to the past, Jeremie then had to reuse the tower to generate a clone of William to avoid suspicion about the real one's disappearance. In Wreck Room, X.A.N.A. only managed to take over the tower used to maintain the William clone, because of a bug which cropped up from one of his programs has messed up its security programs.

Jeremie uses a scooter to get to and from the Factory like Aelita, but is afraid of jumping over the obstacles because he is not so daring like his friends.

Jeremie, Jeremy, and Jérémie are all French or English variants of the Hebrew name Jeremiah (ירמיהו), which roughly means God exalts me. Jeremiah is also a major prophet in Judaism, Islam, and Christianity who is associated with the phrase "Attack you they will, overcome you they cannot," a reference to Jeremie's ability to continually keep X.A.N.A. at bay throughout the series. The surname Belpois is a French surname of unknown origin and etymology, although it is relatively common in northeastern France.


  • In the Japanese dub, he was named Jeremī.
  • In the Indonesian dub, he was voiced by Hana Bahagiana.
  • He shares the same voice actress with Aelita in the English dub.
  • Jeremie was named after Jeremie Perin, an old classmate of Thomas Romain's; this was revealed by Romain himself on Twitter.
  • After Code Lyoko became popular in countries other than France, the production team decided to officially change his name to Jérémy (Anglicised as Jeremy), but a lot of long-time fans still use the old spelling of Jérémie or Jeremie. All official post-Season 1 media refers to him as Jérémy or Jeremy for this reason.
  • During the first half of Season 1, Jeremie's voice was a little high pitched. However, during the rest of Seasons 1 and 2, Jeremie's voice was much deeper. This is a result of his voice actress trying to mimic a French accent. From Season 3 onward, his voice was slightly deeper than his voice in the first half of Season 1, but not as deep as in Season 2.
  • He is the only Lyoko Warrior in Evolution to have an episode named after him; Jeremy's Blues.
  • Jeremie has earned the nickname "Einstein", due to his impressive intellect. In the second season, Sissi starts calling Aelita "Mrs. Einstein", a hint towards their romantic relationship. Jeremie also has a poster of Albert Einstein on the wall in his room.
  • Jeremie's father, Michael, has only made two appearances in the series; the first one being at the near-end of the episode Franz Hopper and was also seen in Distant Memory. Also, Jeremie's cousin, Patrick, has made his first and only appearance in the episode Cousins Once Removed. Jeremie's mother, however, has never been shown, but she is confirmed to be alive.
  • Jeremie often gets self-absorbed and orders around the other members of the group around, such as in Image Problem, often giving orders as if the group was a military organization.
  • The line about Jeremie wearing "underwear with kangaroos printed on them" is a mistranslation. It originally meant "kangaroo" style, or "brief" underwear, sometimes derisively known as "tighty-whities".
    • When Ulrich said he would tell Jeremie to switch to boxers in Temptation, it looks like he did, as seen in Tip-Top Shape, when Jeremie is shown wearing red boxers.
  • He has been virtualized three times (Frontier, Ghost Channel, and Mister Pück), and only two of the three times he was able to get to Lyoko without any problems.
  • Jeremie's Lyoko form has yet to be shown and will likely never be shown. As he stated in Mister Pück, he would never go to Lyoko again and prefers his job of virtualizing the team, their weapons, and vehicles. Only information about Jeremie's Lyoko form is Odd's statement that it looks ridiculous.
    • In the novels, Jeremie's Lyoko form is identical to the Disney incarnation of Peter Pan.
  • Despite his apparent athletic incompetence, Jeremie appears to be a talented swimmer, as shown in Laughing Fit and Déjà Vu.
  • Jeremie is the only one of the team's boys who is successful at a scientific school subject and is the only one of boys who's not good at gym.
  • In Cold War, Jeremie stated that his grade point average is 99.87 out of 100.
  • In Final Round, it is revealed that Jeremie likes to have hot chocolate, cereal, and maple syrup for breakfast.
  • Jeremie may have had a crush on or a small attraction to Yumi as his clone was flirting with her in Double Take.
  • It is revealed in the Evolution episode False Pretenses that Aelita calls him "Proxy-Pie" when they are alone.
  • Jeremie was a main character in the game Quest for Infinity, but he wasn't a playable character.
  • Jeremie's first production appearance was in Les enfants, the prototype to Garage Kids. He was the character who loaded the film reel. This is noteworthy because even in early character incarnations, he was always the technically capable one.
