"I'd rather not talk about it."

–Jim's trademark phrase whenever he wants to avoid talking about his past life.

Jim Morales is the strict but lovable Physical Education teacher at Kadic Academy, as well as the campus supervisor, health teacher, and martial arts instructor. 


Jim is an adult male, perhaps middle-aged, and characterized by his red sweatshirt and sweatpants. He is somewhat overweight with a paunchy belly and love handles but is still physically fit, evident by his hairy muscular arms. He has a bandage on his left cheek and almost always wears a headband, which holds up his brown hair in a somewhat spiky hairstyle. He also wears a white T-shirt and dark sneakers.


Jim's tough-guy exterior accurately shows off his strictness and no-nonsense attitude when it comes to the students of Kadic. He is constantly seen trying to enforce the rules of the school, even going out of his way to catch troublemakers in the act. He is also very tough on the students in his gym class and demands they always give it their all. His drill sergeant-like way of teaching shows just how passionate he is for sports and physical aptitude.

Unfortunately for Jim, however, he is also considered to be somewhat of a joke by most of the students at Kadic. His occasional clumsiness, odd mannerisms, and overly-dramatic way of talking can quickly shatter any semblance of intimidation from most of the students, and it is also seen in Nobody in Particular that most of the student body is not very afraid of him.

This does not mean that they do not respect him, however. Jim cares about his students greatly, and is willing to risk his life in order to help them if necessary. He tried to tell stories to comfort the children in Cold War, and single-handedly fought against swarms of Kankrelats brought on Earth in False Start. Over the years he has generated a sort of personal friendship with many of his students, including the Lyoko Warriors, and is also admired by the students for his surprisingly vast array of talents. The most notable of these is his experience from his short-lived disco career, which (as seen in William Returns) quickly turned him into a school celebrity.

In everyday life Jim is known for his occasional boasting. He has a strong moral code as well. In Code: Earth he accidentally made Jeremie hurt while trying to discover Jeremie's secret, and admitted to Jeremie that he deserved to be fired because of it. He prefers if his friends (including the Lyoko Warriors at one point) call him "Jimbo", which is what he claims his friends call him. Jim's favorite color is pink, and his cell phone is covered in gemstones and sparkles.


In X.A.N.A. Awakens, Part 1, he tells Ulrich and Yumi an embarrassing story about himself. He thinks he was brave and clever but Ulrich and Yumi laughed. Ulrich then says "Honestly, I think you would've been better not talking about it." This supposedly started the famous, "I'd Rather Not Talk About It" saying.

In Teddygozilla, he yells at Milly and Tamiya for being in the tool shed, which has rusty and sharp tools. He tells them the dangers of the tools for a couple of "little girls" like them. He then grounded the two girls from attending the school dance when Milly snaps at him and throws a fit, despite Milly being the only one acting inappropriately. 

Twice in the series, Jim has been possessed by X.A.N.A.. The first time was in Final Mix and the second time was in Lyoko Minus One. While being possessed, Jim has shown to have super strength, super durability, super speed and leaping power, shooting lightning out of his fingertips (blue in his first possession, purple in his second possession), and the unique ability to split himself into two forms.

In Final Mix, he is possessed while trying to put the students' final exams away to Mrs. Hertz locker, and ties up Jeremie in his room and electrocutes Aelita while she was on the DJ board, and pretended to take her to the infirmary, but instead took her to the Factory where he virtualized her to the Desert Sector so the Scyphozoa could steal her memory. Jeremie, however, was able to get Kiwi to get Odd, Yumi, and Ulrich to follow him back to Jeremie's room, and the group went to the Factory, where Odd and Ulrich stayed back to fight Jim, who then split himself into two to make things worse for them. He was eventually knocked out, but later got down to the lab, took brief control over the Supercomputer to manually devirtualize Odd, defeated Yumi, and attempted to attack Jeremie, but before he could do any damage, Aelita deactivates the tower, freeing Jim of X.A.N.A.'s control, and in a rare moment, doesn't pass out after being xanafied, but loses his memory of the incident when Jeremie launches a return to the past.

In Lyoko Minus One, he along with Mrs. Hertz and every student from Yumi's class got possessed by X.A.N.A. during a field trip, and fought with Yumi, chasing her through the woods, and eventually caught up to her where Ulrich and William came to her rescue. Though they were able to beat up the possessed students, they were unable to defeat Jim and Hertz, who knocked out William and proceeded to try and kill Ulrich and Yumi, but then passed out and got released from the possession after the Forest Sector (where the activated tower lay) got deleted by a X.A.N.A.-possessed Aelita.

He also suffered related attacks, such as getting bitten by a X.A.N.A.-fied Kiwi and turning into a zombie in Attack of the Zombies, and going crazy by X.A.N.A. taking over the phone network and partially possessing him with a spectre in Bad Connection, though he doesn't gain any powers from this possession and maintains most of his personality other than a desire to kill Odd and Sissi. 

In Nobody in Particular, Jim also got possessed by Ulrich in spectre form after he accidentally got separated from his body. Here, he managed to use Jim as a way of convincing Mr. Delmas, Mrs. Hertz, and the other teachers into letting Ulrich stay in class with Odd, Jeremie and Aelita instead in remedial class.

In Echoes, after the Lyoko Warriors shut down the supercomputer, they bump into Jim who asks what they were doing, and after Odd answers him, Jim reveals that he also gave up his teenage dreams to become an adult, and when Odd asks him if he's really an adult, Jim as usual says he'd rather not talk about it.

Job at Kadic

Jim is shown to be much more than just the school's Physical Education teacher, this is a list of jobs that Jim has had at the school.

  • He is shown to be the school's handyman, often having to use his strength to move large items and fix doors and windows.
  • Jim is the campus supervisor and is in charge of student discipline, and is very strict (most of the time) to students who break the rules.
  • Jim is shown to be the health teacher in at least one episode.
  • He was also the school's librarian in at least three episodes.
  • Jim is also the school's swim coach as a part of PE classes.
  • He was the coach of the school's soccer team in Zero Gravity Zone

List of Jobs / Skills and Abilities

Jim has claimed to have held many jobs over the course of his life. Most of these jobs he would rather not talk about.


  • United States Navy Seal trainer: He has said this on many different occasions. He has been shown to be a capable fighter and has held his own against a spectre.
    • It should be noted that there is no such thing as a "United States Navy Seals Trainer" and that means he was mostly a Drill Sergeant for the Navy seals. An interesting point, however, is the fact that The Navy Seals are trained by active duty seals, meaning that Jim Morales was a Navy Seal. 
    • When he saluted to the police officer in A Bad Turn, he gave his name, rank, and serial number. For those who are unfamiliar with the military, they are supposed to give your name, rank, and serial number when captured.
  • In Exploration, Jim briefly mentions a job he had working in the sewers.
  • Jim speaks of his time as a volunteer test subject for space exploration in Cold War; he talks about it in the form of a story to the children.
  • A swimming lesson in Déjà Vu reminds Jim of the time he used to be a salvage diver.
  • In Tip-Top Shape, Jim is reminded of the time he worked in a psychiatric hospital.
  • In Straight to Heart, it is mentioned that Jim's desire to form a school basketball team may be due to his past as a ball-player.
  • In that same episode, Odd discovers Jim's career as the star of a 1970's disco film, entitled Paco, the King of Disco.
  • In False Lead, Jim mentions his experience as both a secret service agent and a TV cameraman.
  • In The Pretender, Jim recalls his time as an investigator of paranormal phenomena for a highly special secret-service section. He also mentions that his time there was a highly classified defense secret.
  • In Temporary Insanity, Jim mentions the time he wrote a one-act/one-scene play.
  • In Nobody in Particular, it is said that Jim once claimed to have been a professional ballroom dancer in Buenos Aires.
  • In Double Trouble, Jim describes his time as a war photographer. In the same episode he also claims to have been a safecracker, before quickly changing his mind and instead saying 'locksmith.'
  • In Final Round, Jim reveals that he was a professional skateboarder and when Ulrich asks if he'd "rather not talk about it" Jim says that he would love to but he couldn't because he was hosting the skateboard tournament.
  • In Opening Act, Jim mentions both his time as a special forces agent and the time he fought against 'hurricane windstorm back in '94.'
  • In Wreck Room, Jim says he was an interstate Ping-Pong (Table Tennis) champion, and that he earned the nickname 'the killer racket.' Jim also mentioned that he would have been happy to talk about it for once.
  • In Skidbladnir, Jim discusses his time as a math teacher in the Tropics. He also mentions multiple survival scenarios, including a time when he was forced to bail out during a storm in the North Atlantic and a time when he was stranded alone in the jungle with nothing but a cigarette lighter.
  • In Maiden Voyage Jim discusses the time he used to fight forest fires.
  • The episode I'd Rather Not Talk About It focuses more on Jim's past than any other. Many careers are mentioned or alluded to, including scuba diver, Marines special forces, N.A.S.A. test dummy for space suits, and a secret service agent. He also mentions the time he received a medal from the president, the time he hunted Quebec forest arsonists, the time he went to Buenos Aires 'with his cameras', and the time he orbited the Earth (which he referred to as a 'surprise'). Jim also reveals that before any of this, his initial focus was on completing his training to become a P.E. teacher.
    • Jim explains this as a story to the children, and it is implied that all of these jobs are connected somehow but the episode's structure makes it difficult to ascertain. Also, images shown to the audience imply that some of these jobs are not nearly as glamorous as Jim is making them out to be.
  • In Suspicions, Jim claims to have toured with a band called The Rocking Stones in Europe.
  • In The Warrior Awakens, Jim mentions encounters with numerous wild animals, including a particularly dangerous fight involving fifteen tigers in Burma.
    • However, it is also shown in this episode that Jim enjoys watching nature documentaries, and that he makes a point of hiding this from the students. This may imply that Jim is 'borrowing' details of his stories from TV.


  • Jim is a decent fighter for the most part in the main series and was able to hold his own for a while against a polymorphic clone. He teaches Pencak Silat classes at the school, so he is thus a master of that martial art.
  • Jim is shown to be an excellent shot, as evidenced by the fact that he was pretty adept at killing Kankrelats in False Start, with a nail gun. 
  • Jim has beaten Ulrich in a one on one fight, saying to him that he still has much to learn.
  • Jim has trained the team for at least a week in navy seal boot camp (minus the swimming), although it looked closer to basics boot camp. 
  • Jim is shown to be excellent at hiking, swimming,survival, and any outdoor activity.
  • Jim is shown to have a basic idea of how the school's electrical system works, in X.A.N.A. 2.0.
  • Jim can also play trombone, as demonstrated when he tried to join the Pop Rock Progressives.
  • In spite of his pension for injury coupled with his age and physique, Jim has a surprising amount of resilience and stamina as shown when he wasn't even winded from training with the Lyoko Warriors.

Relationship with the Characters

Lyoko Warriors

  • Jeremie Belpois: In the first season, he was very suspicious of Jeremie and his friends because they kept disappearing during classes. By the end of Season 1, Jim made it his mission to find out his secret, which lead to him being fired when he accidentally injured Jeremie. Jim is shown to be nicer to Jeremie in later seasons, but not by much. In the episode I'd Rather Not Talk About It, he and Jeremie bond while hiding from X.A.N.A.'s boar and Jim inspires Jeremie to try to become stronger. He was impressed with how Jeremie was able to tend wounds and said to him that he has guts and he would never left his men under fire.
  • Ulrich Stern: He is Jim's favorite of the group; this is most likely because Ulrich is a great athlete and is a great soccer player. 
  • Aelita Schaeffer: When Aelita first came into the world and the supercomputer was shut off, she fainted and Jim used his training to make sure she was safe. When Sissi told him that she found crying Aelita he took her back to her room. However he has given Aelita detentions for cutting class and being up past curfew when she should be asleep in her bed though.
  • Odd Della Robbia: He tends to have a love/hate relationship with Odd. He finds Odd's jokes hilarious when they aren't aimed at him, but hates the fact that he is a jokester and pranks him. Jim was upset when Odd tried to blackmail him into putting him back with his friends but later tells Jim that he won't do it, which touches Jim's heart and causes him to convince Mr. Delmas into doing it. He is shown to have a collection of Odd's tests because Odd turns them into origami. This relationship was briefly complicated with the minor arc with Jim's short film Paco, The King Of Disco.
  • William Dunbar: Jim is shown to be impressed with William's athletic stature, but hates the fact that he is a "bad boy" and is always breaking school rules. 
  • Yumi Ishiyama: Jim is shown to be very fond of Yumi in most episodes, but will still be hard on her if she breaks the rules.

Faculty and Staff

  • Mrs. Hertz and Jim have an on and off relationship. In most episodes, Jim is flirting with her, or she is flirting with him. She has threatened him on numerous occasions for what would be harassment. However, they both share an appreciation for the outdoors. 
  • Jim was once attracted to the school nurse Yolanda in X.A.N.A.'s Kiss, especially because a polymorphic clone with her appearance kissed him on the cheek, which led to him going to the infirmary to give her a flower, which she, although flattered, declined because she was already engaged. When Jim asked her why she kissed him, Yolanda started thinking he was ill and asked to check out his temperature, much to Jim's disappointment. Aside from a small hint in Tidal Wave, Jim hasn't shown much interest in her since.
  • Mr. Delmas and Jim generally get along pretty well. Mr. Delmas is shown to have a good amount of faith in Jim and usually trusts his judgment, despite how he is somewhat forgetful. Mr. Delmas does fire Jim after he became sick and tired of Jim being convinced that Jeremie, Ulrich, Yumi, and Odd were up to something, and accidentally injuring Jeremie.


  • In general
    • Most students either like or hate Jim. This is due to him being very tough on trouble makers. A large amount of the girls in the school love the fact that he used to be a disco dancer. Most of the younger students look to Jim for guidance when they are in danger. Jim also cares deeply about the students, and almost dies fighting the Kankrelats with a Nail-Gun in False Start. Some girl students fawn over Jim due to his previous movie role as Paco in Paco, the King of Disco.
  • Sissi Delmas
    • Jim is usually very hard on her, due to her being the Headmaster's daughter and won't tolerate any insubordination from her. However, he has shown some care for her on at least a few occasions.


Jim is a diminutive of the English given name James, itself deriving from the dialectal variant of the Hebrew name Ya'aqov (יעקב), which is also the origin of the name Jacob. Morales (spelled Moralès in the French version of the series) is a surname of Spanish origin, derived from the Spanish words mora, moral, or morera, all meaning mulberry. The name originally referred to people who lived near mulberry bushes.

In English, "Jim" is a homophone to Gym, which is the class he teaches.
