Big glasses, vintage shirt, altar boy hair… Jeremy is the living incarnation and the allegory of the nerd… which goes well with the geek he is. But Jeremy is more than just a simple geek. It's above all a highly gifted tenth grade student, overwhelmingly early above his collegues… Jeremy is the youngest of the group, which doesn't make him, less mature… This permits him, in the past, to be the leader of the Lyoko-warriors, in the controls of the Supercomputer during a virtual war against the artificial intelligence XANA. More gifted than anyone about computers, the experience acquired during the first conflict against XANA clearly eludes Jeremy from the other geniuses of his age.

In school, he obviously is the first of his class… Except in sport where everybody gets ahead of him, even the girls.

Jeremy, despite his young age, has a disposition of leader. It is in particular explained by his great maturity and his higher intelligence. Even his rôle in the team, namely the operator of the group when the others are in Lyoko, positions him as a leader.
Jeremie often takes control… and with it, the decisions. It's him who is decisive on who pilots the vehicles (Episode 04 «Miss Einstein») or on which members of the team has the necessary diplomacy to make a video conference with Tyron (Episode 16 «Confusion»). He also makes most of the time the decision to send people in mission or to let them in the background. In this way, he fulfils the rôle of manager of the team.

Jeremy thinks extremely fast. In the episode 17 «A Professional Career Guaranteed», Jeremy immediatly unmasks Graven, Tyron's envoy, and adapts his behaviour to avoid being caught.
He also keeps his cool. However, we can't realize it because it frequently happens to Jeremy to panic. However, we must be objective. This young teenager has a heavy burden. The life of his classmates are in his hands when they are in the virtual world. And the fate of the Universe depends of the fight against XANA. His regular loss of composure are logical because Jeremy is always facing crisis situations.
According to the cases, Jeremy can panic and goes to pieces until he makes mistakes (Episode 23 «Jeremy's Blues»). In other cases, the adversity stimulates him to find solutions.

Jeremy is a relentless worker and a determinated person. He never backed down to the idea of working consecutive peak hours on a problem. It is frequent to see him spending a whole night to work on the conception of a virus which has to destroy Tyron's Supercomputer (Episode 18 «Tenacity»).

Jeremy isn't a man with field work. That's lucky : Not being a carrier of XANA's source codes, he is safe from specter's attacks. He is facing it only once (Episode 11 «Rendezvous») and acts with courage.
The young geek is yet a little bit cut from the reality of the fields and the fights. He worries when the fights are beaten on Lyoko.

The little top of the class is also a little bit competitor. He doesn't take weel the fact to be blocked on a simple exercice and to be pipped at the post by Laura (Episode 04 «Miss Einstein»).

When we come to the human relations, Jeremy clearly has hang-ups. It's at this moment that his extreme rational side sidelines him. Of course, he is more familiar with friendhsip and love than Laura is. Yet, the little Belpois stays a person relatively cold and stiff.

At first, Jeremy is no good at quarrel. His decisions being rational, he has difficulties to react face to «emotive» situations. We feel him very ill-at-ease when he has to tell William that his place in the group is not topical (Episode 02 «Cortex»). He also is completely bothered face to Laura's father, when this one arrives to the laboratory (Episode 12 «Chaos at Kadic»). The man certainly representing a sort of authority for Jeremy, he doesn't know what to say.
We also remark that Jeremy stays neutral about the case Laura. If Aelita clearly indicates her hostility to the newcomer, Jeremy stays very neutral in the negotiations around her integration to the group. Except the last episodes with the blonde girl, when the situation gets out of control, Jeremy is opened up to Laura, that he surely considers from a professional point of view as ally of value.

About friends, Jeremy has few contacts with Ulrich and Odd, who are more like go-getters than intellectual peoples. He sometimes has clear difficulties to stand Odd and his irresponsible behavious (Episode 02 «Cortex»). He seems closer to the girls, all more thoughtful.

About love, Jeremy is in love with Aelita. They have an ambiguous love relation. They don't show physically their love, their relation being purely platonic. Yet, no one bats an eyelid when William appoints Aelita as Jeremy's girlfriend. Jeremy never express his feelings about Aelita, but it happens to the young girl to confess her emotions for Jeremy.
The genius betrays himself with only one element : the worry and the overprotection for everything related to Aelita. He is ceaseless advising her caution and worrying for her. While he always reasons in a very rational way, Jeremy is ready to make concessions for Aelita, when questions about Anthea Hopper are at stake. In a general way, we couldn't be more devoted for Aelita than Jeremy is.
In the episode 11 «Rendezvous», Jeremy even lets the checkpoint to Laura to rescue Aelita. He also bears her mood swings, feeling empathy for her.

In short, let us make no mistake : Jeremy and Aelita love each other.

Jeremy is the operator. He guides his friends through the virtual universe and its dangers. Jeremy virtualized in the past, time and again. He won't have the occasion to repeat the experience during this new conflict against XANA… and anyway, he didn't really wanted to.

Jeremy is an outstanding computer expert. He is able to create very complicated programs, very fastly, like the famous Megapod which permits to cross the ring of the Cortex (Episode 04 «Miss Einstein»). Like his friends progressed at fight on Lyoko and on Cortex, Jeremy progresses. Around the end of the second conflict, he finally reprograms the Skidbladnir extremely quickly (Episode 23 «Jeremy's Blues») whereas it should take weeks.

Jeremy is, in a general way, the best. He is often assisted with Aelita. However, it happens to get stuck in some problems. This is the way he decides to call upon Laura to obtain some help (Episode 08 «Virus»). Laura is not specially more clever than Jeremy… nevertheless, as we sometimes say, two heads are better than one. Laura is, in particular, an expert in viruses… a computer field that Jeremy didn't have the occasion to explore. So, if the blonde girl surpasses our hero at this point, we see her unable to simply virtualize the Skidbladnir (Episode 22 «Mutiny»). The two geniuses have their area of competence.

In the virtual conflict, Jeremy is on all fronts. Jeremy advances the heroes to the truth with discovering the link between XANA, the specters and the heroes : the famous source codes. He also discloses the identity of Tyron.

He eludes at the same time the possible bugs of the Superscan with creating portable mini-scans (Episode 12 «Chaos at Kadic») and XANA's traps (Analysis of the structure of the Blocks' wall from the Episode 07 «Countdown» ; luminous revealance of the Doppelgänger in the episode 21 «False Pretences»). He beats XANA at its own game twice : In the episode 09 «How to fool XANA», he inspires Ulrich with fakes codes to destroy a specter and weaken XANA. In the episode 19 «The Trap», he leads a specter to a trap and steals it codes.

He also analyses Tyron's virtual phenomenons in order to thwart them (Like the time distortion in the episode 24 «Temporal Paradox»). He always finds a solution to the crisis situations. For example, in the episode 17 «A Professionnal Career Guaranteed», he gets rid of Tyron's transmitter with sending it back to the sender.
It even happens to face possible urgent needs, like generate a clone of Aelita to replace her in Kadic (Episode 20 «Espionage»).

Jeremy also manages the simpler protocols like hacking, datas stealing and spying the Supercomputer of Tyron (Episodes 06, 18, 20…). He recovers an important archive video to discover Tyron's identity thanks to a numeric deinterlacing (Episode 07 «Countdown»).

But nobody is infallible. So, it happens to Jeremy to get nabbed. Tyron lets him steal fake datas to fool Jeremy's vigilance (Episode 14 «Intrusion»). XANA entices him in a trapped hub and destroys the Skidbladnir (Episode 23 «Jeremy's Blues»).

The history of Jeremy and Aelita is a little bit Code Lyoko Evolution's history. So it is tenuous to summarize it. For more informations, the simplest way is to consult the page History of Code Lyoko Evolution.

Jeremy, even after himself shut the Supercomputer down, became again a normal teenager, especially brilliant, and appreciating the classes, except the ones from his tyrannic sports teacher, Jim Morales.

Also, when strange phenomenons began to assault Kadic, Jeremy stayed doubtful until Aelita began to sound alarm bells and to mention XANA's return. Quickly convinced by his lady-love, the little genius fastly suggest his friends to turn the Supercomputer on again to check that… After a short mission on Lyoko and the attack of a specter in Kadic, Jeremy understands that XANA is back. It survived with integrating source codes in the heroes before being destroyed… and now, it sends specters to Aelita, Odd, Ulrich and Yumi to take its codes back, recover its power and conquer the network again. (Episode 01 «XANA 2.0»).
So Jeremy elaborates Transwatches to mesure the rate of codes of the heroes and the power rate of XANA.

Jeremy's mission is fastly cut in two axis. He has to help his friends to deactivate the towers when the specters attack. To do this, he takes up again the role of operator, leading the heroes and solving the computer problems like explained in the framework higher. Jeremy is not really concerned by the attacks of specters, because he doesn't have source codes.

The second quest will, on the other hand, require all his attention.
While searching where XANA found refuge, Jeremy reprograms the Skidbladnir, sends the Lyoko-warriors in the Network and progressively finds a new virtual world, the Cortex (Episode 02 «Cortex»). This world is generated by a Supercomputer visibly linked to the Professor Hopper. The genius programs a vehicle for his friends to evolve in this moving and dangerous Sector : the Megapod (Episode 04 «Miss Einstein»). Entering in the Central Dome of the Cortex and with the help of DMA peripherics that the virtual fighters insert in the interface of the Cortex, Jeremy steals datas.
He discovers that this Supercomputer is the propriety of Lowel Tyron, an old colleague of the Professor Hopper. Tyron would have betrayed Hopper with stealing the models of his Supercomputer and building a similar one (Episode 07 «Countdown»). Jeremy doesn't have a particular grievance against Tyron but because his Supercomputer is XANA's shelter, it must be destroyed. Jeremy and Aelita start to conceive a virus. Stuck with various problems, he decides to require the help of Laura, a newcomer at Kadic, also a gifted child and expert in virus.

Jeremy only wanted her help punctually. Unfortunately, Laura hacks the Supercomputer and the return to the past. She doesn't feel the effects and becomes, de facto, a forced member of the team.

While the specters are incensed and glean little by little source codes, Jeremy excels himself. After a failed first try, Tyron develops Ninjas to protect the interface of the Cortex, dreaded virtual fighters who complicates the investigations in the Cortex.
The genius is, moreover, stuck between Aelita and Laura who have a very virulent cold war. Laura reveals to be a worthy asset. She replaces Jeremy at the drop of a hat to unblock a problem of activated towers (Episode 11 «Rendezvous») when the operator must rescue Aelita. He also calls her for help whe XANA attacks the Skidbladnir with a virus (Episode 13 «Friday the 13th») and almost virtualize her… but Aelita settles the problem just in time.
On the other hand, Laura does big blunders which damages the trust that the group grants.

Aelita, she's pretty bad. The trouble link between Tyron and her father reminds her the difficulty of an orphan life. Jeremy does everything he can to support her… while being very busy to develop the virus with Laura…
While they investigate in the Cortex, the unthinkable happens. During spying the laboratory of Tyron, Aelita discovers that her mother, Anthea Hopper, is alive and bside their enemy. Jeremy thus delays the destruction of the Cortex. He suggests for Aelita to wait that XANA reached 95% of its power, letting her the time to investigate about her mother (Episode 18 «Tenacity»). Clock is ticking all the more since Tyron tries to locate the heroes (Episode 14, 17, 24…).

Laura, exasperated bu this decision, drags William into a duet mission to destroy the Cortex. The mission fails and has had big risks. Following this, Jeremy and his friends expel Laura of the group. With working on the Return to the past, Jeremy makes it work again on Laura who forgets everything.

Unfortunately, the fateful power threshold of 95% of XANA is quickly reached. Aelita rejects her friends' proposition to wait again. The mission in order to destroy the Cortex is finally started (Episode 26 «Ultimate Mission»). After many events for Aelita, faced by Tyron who comes to Kadic, Jeremy sends the virus in the Cortex.
Unfortunately, Tyron turns off his Supercomputer. The virus is implanted in the Supercomputer, however, it didn't get activated. The Supercomputer is off, and if Tyron turns it on, the virus will destroy it… So it is a stand-by situation which closes this second conflict against XANA.

Jeremy turns off the Supercomputer again. Yet, he know that the work for him is not over. Anthea is still alive, somewhere in Swiss near Tyron with whom she has an ambiguous relation. Jeremy will have to support Aelita in her quest to find her mother and the path will be long.
