There are new things in store for the gang on Lyoko: Jeremy has programmed some high-performance vehicles… and X.A.N.A. has some new monsters on it’s not-so-welcoming committee. What’s more, Aelita moves to the Academy to live with her pals! However, life on Earth is no bed of roses for our young heroine: X.A.N.A. has taken over a house in the neighborhood (the Hermitage) and lures the gang there to destroy them! Not only is the Hermitage a dangerous place, it seems to be home to a mystery: when Aelita enters the house, she is overwhelmed by troubling visions…

Unchartered Terri...

#28

While investigating the Hermitage, the house where Aelita has had visions, Jeremy discovers that it once belonged to a Mr. Franz Hopper, a former teacher at Kadic Academy. Even more interesting is the fact that there may be a connection between him, the factory and the Super-computer. Back at school, the other pupils are giving Aelita a hard time. In despair, she decides to run back to Lyoko – what a golden opportunity for X.A.N.A. to kidnap her! While the gang is looking for Aelita, they discover that X.A.N.A. has taken her to unknown sector -- Sector 5! The episode ends with our heroes saving Aelita from the grips of a new monster as it was trying to steal her memory! So who is Franz Hopper really? What will they find out in Sector 5? Why does X.A.N.A. want Aelita’s memory? Our heroes must get to the bottom of these new mysteries!

Exploration

# 29

Now that our heroes have discovered Sector 5, they decide to go and explore it in the hope of unearthing some of its secrets. First, they will have deal with a series of traps…but then they realize that this sector is in fact a part of X.A.N.A. itself. It’s the perfect place to steal information from their enemy. Jeremy sees it as an opportunity to find out more about Franz Hopper, and about the anti-virus which will free Aelita from X.A.N.A.. Back in the real world, Yumi's parents are worried about her nocturnal excursions and decide to keep a closer eye on her. How will she be able to help her friends now?

A great day

#30

X.A.N.A. has gained control of the Super-computer’s “return to the past” program. At first, our heroes struggle to understand why it would do such a thing… but before long, they realize that Sissi has been possessed by X.A.N.A.. She is trying to wipe them out! Then finally, the penny drops; the “returns to the past” have been increasing X.A.N.A.'s power and now their enemy is strong enough to control human beings…New dangers in store!

Mister Puck

#31

Ever since the day Aelita set foot in the Hermitage, she has been plagued by increasingly frightening visions. For a few days now, she hasn’t been able to sleep a wink. Jeremy suggests going back to the house to put a stop to her nightmares once and for all. Once at the house, Aelita’s visions lead her to a strange, familiar-looking plush toy. When Aelita takes the toy to class, Sissi tries to snatch it from her and the two girls end up tearing it in two. A small key falls to the floor. Later on, our heroes discover to their delight that it’s the key to a locker containing Franz Hopper’s journal in the form of 13 CDs! Unfortunately, the CDs are encrypted. Jeremy has his work cut out for him now…

St Valentine’s Day

#32

It’s St. Valentine’s Day! Yumi and Ulrich get into a fight about William. Aelita receives a pretty necklace which she is convinced is from Jeremy. Unfortunately, it’s really a “poisoned” gift from X.A.N.A.. When Aelita puts the necklace on, X.A.N.A. will be powerless to resist the urge to go to Lyoko and hand herself over to the Scyphozoa. Luckily, our heroes arrive just in time to save her…

Final Mix

#33

Aelita steps in for one the DJs at the Academy’s school dance. Who would’ve guessed whe would have such an ear for electronic music! Jeremy is jealous of all the time she is spending on her new-found passion. Meanwhile, X.A.N.A. lies in wait. With Jim under its control, X.A.N.A. is able to kidnap Aelita and virtualize her on Lyoko so the Scyphozoa can steal her memory. Our heroes must defeat Jim, who has become invincible, thanks to the powers X.A.N.A. has invested him with…

Missing Link

#34

In an attempt to save Aelita from the Scyphozoa, Yumi finds herself engaged in a brutal combat against the monster. Shortly afterwards, Jeremy sees that, as a result of the combat, Yumi can no longer be devirtualized. In fact, it looks like a vital part of her is missing -- her virtual DNA code! How can he get it back to her? After numerous attempts at finding a solution, our heroes realize that the only way to help Yumi is to go inside of X.A.N.A. and look for the “missing link” -- in Sector 5… danger ahead!

The Chips are down

#35

Yumi and her family are going to move away. Her father, Mr. Ishiyama, has been laid-off work and they cannot afford to stay in their current home while he tries to find another job. Devastated by the idea of Yumi leaving, Ulrich gets an idea -- he plans to secretly use the “return to the past” program to buy a winning lottery ticket which he will give to Yumi’s parents. He carries out his plan and, to no one’s surprise, wins the lottery draw. But his friends realize what he has done. They know that returning to the past increases X.A.N.A.'s power. Jeremy and Yumi think that Ulrich has gone too far. How could he be so careless! Their minds are made up -- Ulrich is out of the gang. Meanwhile, X.A.N.A. uses Nicolas to launch an attack. Our heroes are in real danger. Ulrich acts just in time to save them, and earns his place back in the team.

Marabouta

# 36

When Jeremy deciphers part of Franz Hopper’s journal, he comes across an interesting theory about multi-agent systems. It states that while a lone, small program working alone is incapable of the slightest imaginative response, a group of small programs working together is said to be capable of performing highly-complex tasks. Jeremy believes that a program of this nature would be a fantastic weapon to use against X.A.N.A.! On the basis of this latest discovery, Jeremy creates a new program he calls, “Marabounta!” He launches it. At first, “Marabounta” is an effective weapon for our heroes against X.A.N.A.’s monsters, but before long, things start going horribly wrong!

Common Interest

#37

The nuclear battery which powers the virus is running out of fuel… Sensing the danger to itself, X.A.N.A. possesses a criminal to steal some uranium. When our heroes find out what’s going on, they are forced to help X.A.N.A. to carry out its evil plan as Aelita’s survival is also under threat!

A Bad Turn

#39

Today at Kadic Academy, 8th and 9th graders have Driver’s Ed. Ulrich and William both want to impress Yumi, and are at each other’s throats. Meanwhile, X.A.N.A. has launched a new attack. In an attempt to wipe out its enemies (with the exception of Aelita whose memory he needs), X.A.N.A. has found a way to materialize Krabes in the real world. The fight against X.A.N.A. is tougher than ever… and Ulrich and William will be forced to join forces. And that’s not easy for two kids who can’t stand each other!

Tentation

#38

For some time now, Jeremy has been acting increasingly weird. He insists that they keep returning to the past despite what his friends say. They are all too aware of the dangers inherent to returning to the past, namely, an increase in X.A.N.A.'s powers. When our heroes take a closer look into what's been going on, they discover that X.A.N.A. has tricked Jeremy into using Franz Hopper’s notes to build a machine which uses the return to the past process to increase X.A.N.A.’s intellectual capacities tenfold. But the process is jeopardizing Jeremy’s health… and his friends must help him break free of his obsession.

Attack Of The Zom

#40

X.A.N.A. uses Kiwi to spread a virus which turns people into zombies. The zombies are all obsessed with doing our heroes in. The Academy becomes the scene for a real-life horror movie in which the character’s true personalities are revealed. Jeremy and Aelita are stuck inside the cafeteria, as much by the zombies as by William (who takes his role of protecting his fellow pupils a little too seriously). They must escape and get to the factory and deactivate the tower before it’s too late!

Ultimatum

#41

X.A.N.A. has possessed the Headmaster. Mr. Delmas kidnaps Yumi and Odd and gives Jeremy an ultimatum -- Aelita must go to the edge of the Ice Sector on Lyoko within two hours, or Odd and Yumi go bye-bye! Our heroes don’t have a moment to lose! But the police is also looking for Odd and Yumi and they get in our heroes way. Luckily, thanks to a electro-magnetic bomb made by Jeremy, Ulrich eliminates the xanafied Headmaster and saves Odd and Yumi at the last second…back on Lyoko, Aelita deactivates the tower.

A Fine Mess

#42

At the end of another successful mission on Lyoko, our heroes rematerialize in the scanners. But something’s not quite right -- the program has malfunctioned a put Yumi in Odd’s body and vice versa. They are forced to make do as best they can in unfamiliar bodies, while the rest of the gang looks on in amusement. But things take a more serious turn when our heroes realize that Odd and Yumi’s atomic structures are unstable and that they could both disintegrate for good…

Xana’s Kiss

#43

Love fever has taken over the Kadic school! First, Aelita catches Jeremy kissing Heidi! Then, Yumi sees Ulrich kiss Sissi! Jeremy finds out that Aelita is going out with Nicolas! The gang is in serious danger of falling apart at the seams, starting with Jeremy who has a huge falling out with Aelita. Once again, X.A.N.A. is behind it all. This time, it has sent a polymorphous specter which can change its appearance at will to the Academy to divide and rule… but our heroes figure it out with just enough time left to get to Lyoko and save Aelita from the Scyphozoa’s clutches.

Vertigo

#44

Ulrich is afraid of heights… but he’s never dared admit it to his friends. Until one day in gym class, he has to race William up the climbing wall and is humiliated by him in front of Yumi. Crestfallen, he goes off to brood in the woods. Yumi and Odd set off to find him and cheer him up… and that’s when X.A.N.A. decides to attack. It sends a pack of wolves to wipe out our heroes! Jeremy and Aelita must act fast on Lyoko!

Cold War

#45

Using a national television relay station to its advantage, X.A.N.A.’s sends his specters flowing out of antennae and transmitters all over the city. The specters blend into the low-hanging clouds covering the area. A snow storm breaks out, sending the temperature spiralling down to an outrageously cold 60°F below! Staying outside for more than a minute at a time has become impossible and anyone who does so risks having their respiratory tracts freeze up for good. In the midst of such extreme weather conditions, our heroes are faced with a serious dilemma -- How on Earth are they supposed to make it to the factory so they can virtualize onto Lyoko and deactivate the tower?

Déjà Vu

#46

Once again, Aelita is plagued by strange visions which seem related to a past she does not recognize. It is in fact one of X.A.N.A.’s schemes! It stimulates our young heroine’s memory in order to draw her to Sector 5 where the Scyphoaoa is waiting for her! After a long struggle, our heroes manage to counter X.A.N.A.’s attack. But there’s still one question that remains unanswered -- where are these visions coming from?

Tip-Top Shape

#47

It’s time for the annual physical at Kadic school! X.A.N.A. possesses the school nurse, Yollanda, and she captures Aelita. Her goal is to get Aelita to Lyoko and hand her over to the Scyphozoa. For Jeremy, there is only one possible solution -- they must prevent the school nurse from reaching the scanner room! He decides to put a project he’s been working on for some time into action… he activates a tower for his own use, then pixelizes Odd, giving him the same powers as someone possessed by X.A.N.A.. Odd can now fight Yollanda on equal terms! Unfortunately, X.A.N.A. has some ideas of its own to fight back against Jeremy…

Is Anybody Out There

#48

When Sissi hears strange noises coming from the boiler room, she is convinced that Kadic Academy is haunted. When our favourite snob organises a pathetic seance in the basement, XANA sends out a specter. Panic spreads throughout the school! The pupils are all convinced that Kadic’s infamous ghost is making a come-back! Our heroes, on the other hand, know perfectly well that it’s just another of XANA’s schemes and that to destroy the “ghost”, they must deactivate the tower…but how will they get to the factory?

Franz Hopper

#49

A strange man turns up at the computer lab claiming to be… Franz Hopper. Our heroes can’t believe their eyes. But in truth, the man is just another of XANA’s spectres which has taken on a human appearance. He cleverly, yet relentlessly sows dissension in the gang so he can wipe out our heroes and lure Aelita to Lyoko so that the Scyphozoa can steal her memory.

Contact

#50

Our heroes are doing battle with Sissi who is acting very strangely. Could XANA be controlling her? This hypothesis is quickly discarded as Sissi does not seem interested in harming our heroes… rather, she appears to be trying to tell them something. The truth comes to light when an activated tower is discovered on Lyoko -- something or someone else has taken over Sissi in an attempt to contact the gang. After overcoming a series of obstacles and fighting against XANA (which tries to block all contact between Sissi and our heroes) they realize that it’s Franz Hopper (who must be somewhere on Lyoko) who wishes to communicate with them…

Revelations

#51

To make decrypting Franz Hopper’s journal easier, Jeremy decides to activate a tower once more. But while Aelita is transferring data, XANA tries to take back control of the tower and could possibly gain access to the restricted-access part of the Super-computer where Jeremy has stored all of the data he has collected since the very beginning. Meanwhile, Yumi is trying to find Odd, who has fallen into a trap, while on Lyoko, Ulrich is fighting against a spectre which is a clone of himself…

The Key

#52

Thanks to Franz Hopper’s journal, which they have finally deciphered, Jeremy understands what the virus tying Aelita to XANA is -- a “fragment” of Aelita herself that XANA has stolen. They must get it back at all costs if they want to finally pull the plug on the Super-computer and destroy XANA! But Aelita has been thrown into confusion by some of the revelations about herself in Franz Hopper’s journal. In a state, she risks her life by trying to switch off the Super-computer by herself. Jeremy comes to the rescue and manages to persuade her to take part in the final mission in Sector 5 to recover her missing fragment. The final combat against XANA is about to begin…
