Jim Morales

Jim "Jimbo" Morales is the P.E. teacher at Kadic, and hosts most extracurricular activities such as the Robot Competition, the Annual Skateboarding Tournament and soccer practice (though in the second season he seems to not have any memory of those at all). He is very suspicious about Team Lyoko, and thinks they are up to "no good". He sometimes almost catches them in the act, and was a member of the Lyoko Warriors (though was never scanned into the Supercomputer) in Code: Earth and False Start, before unfortunately getting his memory erased, although he first found Jeremie talking to Aelita in Ghost Channel. As of the second season, he addresses the students by last name only, further adding to his primary attitude.
He is also the campus supervisor, as well. This job is very important, because he actually likes the kids that he has to look after, and he wants to keep them safe, in the best ways he can think of to protect them all. He also wants to protect Team Lyoko themselves, perhaps knowing that XANA wants to destroy them. To add to this, he seems to have a pretty friendly relationship with Yumi, despite the fact that he often is tyrannical around her and the other kids. Jim is very meatheaded and dull-witted, and can forget what he was going to say halfway through a sentence. He is also referred to on Kabillion.com and Codelyoko.com as a "tyrant" and "moronic musclehead", but this can be considered by some fans to be a bit of an exaggeration at best. He is called other insults by the children as well, such as "dipstick" and "idiot" (by Sissi in Log Book in her diary), "GI Jim", "big fat clown" and "Incredible Hulk" (by the Lyoko Warriors), and other insults. He also is a perfect target for school pranks as seen in Nobody in Particular. He is also fairly clumsy and can be seen stumbling over his own feet during his demonstrations in his PE classes, causing the children to laugh at him derisively. He does not tolerate disobedience of any kind, and will not hesitate to punish and yell at the children if they disobey his commands, but occasionally his idea of "discipline" can cross the line (as indicated by Milly in A Lack of Goodwill). He especially dislikes the Lyoko Warriors because they often skip school to go to the Factory. Thus, they sometimes see him as a obstacle. However, despite this fact, he often helps the Lyoko Warriors fend off XANA attacks.

Jim in Season 4

According to a running gag in the second season, he claims he has many other jobs over the years, but every time someone asks if he did have the job he says "I'd rather not talk about it" in an embarrassed tone. This is a clear hint towards his firing in Code: Earth. This running gag was temporarily broken in the episode Cold War. 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. This was also challenged in Wreck Room when Jim said that he was a professional Ping-Pong (Table Tennis) player, he said that he would have been glad to talk about it when several children declined his offer for a game.
Jim is very strong (he was able to pick up both Ulrich and William up at one time). In Teddygozilla, he called Milly "little girl" when he was yelling at her and Tamiya for being in the Garden Shed, which hurt her feelings; he didn't appear to show any remorse for what he did at the time, and he angrily grounded them both to their room; he later got beaten up by Milly's teddy bear. Along with this, Milly described Jim's attitude as well ("With you, everything's off-limits."). But he can act rather differently to the children at times, as seen in Cold War when he's protecting the children in the boiler room of Kadic, later telling them a story about his time as a Space Exploration Volunteer Test Subject and in The Lake when he comforted some of the children by telling them that the "monster" would have to "deal with him" in order to get to the kids (giving them a loving embrace in the process). He often accompanies Mr. Delmas, and could be considered his aide and bodyguard; he also seems to have an on-again, off-again loving closeness to his daughter as well, as first demonstrated in Holiday in the Fog when he is protecting her and comforting her by assuring that Jeremie couldn't be too far away from the school. As he stated to Milly's Teddy Bear in Teddygozilla, he also has a black belt in some martial art (presumably in Pencak Silat, as hinted at in XANA Awakens Part 1 and shown directly in Canine Conundrum, where it is revealed in the latter that he teaches Pencak Silat classes at the school). He prefers if his friends (including Team Lyoko at one point) call him Jimbo, which may derive from the Japanese word for bodyguard.
Some fans see him as a candidate Lyoko Warrior, even writing fanfics with him as a warrior and with knowledge of the Supercomputer and Lyoko. As a matter of fact, he fought some Roachsters in False Start.
Jim is voiced by David Gasman.

Jim's many jobs

As a running gag in the series, beginning with the second season, any situation Jim is involved in will inevitably lead him to relate it to a former job of his. However, rather than proceed to explain, he will refuse to go on ("I'd rather not talk about it.") and change the subject. Failing that particular gag, something (or someone) will usually interrupt him or a different excuse will prevent him from continuing.
In order, he has been, or has mentioned being:

• A sewer worker
• A soldier (comically portrayed in A Bad Turn)
• A "Space Exploration Program Volunteer Test Subject" (Cold War, he does talk about this one in the form of a story to the children)
• A salvage diver (Deja Vu)
• An actor
• A disco dancer (Straight to Heart, Odd uses Jim's Paco, King of Disco video to blackmail him)
• A worker at a psychiatric hospital (Contact, he was referring to Sissi's weirded-out condition)
• A forest ranger in Quebec (XANA Awakens Part 1, and The Lake; Suzanne interrupts him the second time and just tells him to cut the chatter and go get the first-aid kit)
• A martial arts master, particularly in Pencak Silat, which he followed with another ridiculous story of using his skills to fight off a beaver (XANA Awakens Part 1). It is also evidenced in Canine Conundrum, where he reveals that a Burmese pendekar taught him his moves, and he gives a demonstration of said moves.
• A former basketball player, playing pro-ball (Straight to Heart)
• A former government agent (False Lead, he claims the experience is classified)
• A professional ballroom dancer in Buenos Aires (Nobody in Particular; mentioned by Suzanne)
• A war photographer (shown in a dream of his)
• A safecracker and/or locksmith (Double Trouble, he said the first one but corrected himself)
• A cameraman
• A skateboarder (Final Round, he was busy and thus didn't talk about it)
• A paranormal investigator (like with the government agent job, he says its classified; the two occupations may be tied)
• A Special Forces agent on a mission in Las Vegas (one of Xana's attacks leaves this one unheard)
• A champion table tennis player (Wreck Room, Yumi convinces him not to talk about it)
• A math teacher (Skidbladnir, he claims he taught math in the forest, but of course shows no understanding of it)
• A firefighter (claimed to have fought forest fires)

Since Jim has been employed at Kadic for 21 years in the series proper, he either did not hold these jobs for very long or simply lied about them, the latter implied by the non-sequitor explanations he occasionally gives in regards to these jobs. Obviously, at least some are true or exaggerated, namely his stint as a disco dancer, but which ones are left open to interpretation.
Jim's signature line, "I'd rather not talk about it", is hinted to have originated from Ulrich in Xana Awakens, where after hearing a rather strange tale from Jim, Ulrich suggests that he would be better of "not talking about it". His nephew, Chris, also repeats the line in Opening Act, after having auditioned a string of less than spectacular candidates for a position in the band.
In the episode I'd Rather Not Talk About It, Jim gave the five kids a brief rundown of his various careers and gave each a description. At the same time, Jeremie visualized scenarios that Jim could have been doing, which seems a lot more realistic considering Jim's educational limits; an example being when Jim said that NASA asked him to test their space suits out underwater. Jeremie visualized him being the pool cleaner for the tests which appears more realistic.
