Teddy-Godzilla

Written by Fred Lenoir

The X.A.N.A. virus has mounted another attack against our planet. This time, it has taken control of little Milly’s teddy bear. Milly is a student at the same junior school our heroes. Not only does the teddy bear come to life and become very aggressive, but he grows to be as big as a building before our very eyes. The safety of the whole city is in jeopardy. While Ulrich rushes off to help Yumi, Odd will have to fight on Lyoko alone – with Jeremy acting as his moral support and guide -- so that their virtual friend Aelita can foil the X.A.N.A’s attack. In the meantime, Yumi and Ulrich, with Milly in tow, will have to pull off something pretty amazing if they want to escape the giant teddy bear’s terrible grips.

Seeing Is Believing

Written by Françoise Charpiat

While Odd is trying to form a new band, the X.A.N.A. takes control of the school’s electricity supply. Leading the investigation, our heroes understand that the fiendish X.A.N.A. computer is also planning on blowing up a nuclear power-plant. A little concentration during gym class will help them make the right decision! In fact, the danger is so great that they decide to reveal the existence of Lyoko, the virtual world that only they know about, to the authorities. But it all seems so far-fetched that in the end, no-one believes them. Yumi, Aelita, Jeremy, Odd and Ulrich have only themselves to turn to stop a nuclear explosion from destroying the city.

Holiday In The Fog

Written by Laurent Turner

Jeremy manages to get himself grounded for the whole school holiday period. He wants to be there in case X.A.N.A., the virus, should decide to launch an attack over the break. Sissi, who suspects Jeremy, has secret activities, works things out so that she is also at school during the holidays. The Headmaster has put Jim in charge of watching over the two young people. Jeremy’s fears are confirmed when X.A.N.A. succeeds in spreading highly-toxic fumes throughout the school, posing a direct threat to Jim and Sissi who are holed-up in a tiny little room. Jeremy must face the X.A.N.A. all by himself, so let’s just say that it’s a hopeless situation. He calls Yumi, Odd and Ulrich to the rescue. Will they get back to school in time to lend him a helping hand?

Log Book

Written by Françoise Charpiat

Sissi uses Ulrich’s diary against him so that he will be forced to pay attention to her. The diary contains details of Ulrich’s secret activities and of the existence of Lyoko. She takes advantage of a school trip to the swimming pool to attack. But this is no time for Ulrich to get caught in a trap because X.A.N.A. has taken control of the electric school bus he and the other students are travelling in. The bus, which has now become a kind of prison-on-wheels, is speeding towards the city’s chemical complex. Only the skills and daring of Odd, Yumi and Aelita on Lyoko can stop the crazy bus and save it from a deadly catastrophe …

Big Bug

Our heroes are faced with an urgent situation. They must counter X.A.N.A.’s evil plan and stop this deadly collision from occurring. And to think that Sissi is going to go after Ulrich again and make our dream team’s mission even more difficult !

Cruel Dilemma

Written by Alain Serluppus X.A.N.A. doesn't let a single detail of life at the school get by him. The Headmaster has decided to make extensions to the gymnasium and the virus wastes no time before turning the bulldozers from the construction zone into weapons. Our heroes must nip this new attack in the bud before the metallic army has a chance to destroy the factory, thus making it impossible for them to get to the secret laboratory. During the battle, taking place on Lyoko, Yumi falls into the digital sea, and turns into a virtual character forever. It's a cruel dilemma for Jeremy who has just accomplished his life’s work by working out how to make Aelita into a real person. But he can only bring one person to life: will it be Yumi or Aelita ?

Image Problem

As she is unconscious, Jeremy, Ulrich and Odd take her to the infirmary. When she wakes up, she starts acting strange, insisting that they take her back to the factory. Her friends are still wondering how it is that she was sent back to the real world before it was time… What the boys don’t know is that the real Yumi is still on Lyoko, held prisoner by X.A.N.A., while an evil and almost indestructible clone has taken her place in the real world. The clone has but one mission - to destroy our heroes! An unsuspecting Jeremy sends Odd and Ulrich to Lyoko to help Aelita deactivate a tower. In so doing, he ends up alone, face-to-face with the real X.A.N.A. creature. Only the real Yumi, once she is freed by her friends and gets back to the real world, can face up to the clone at the last minute.

Seeing that her heart’s desire is suffering from amnesia, Sissi takes full advantage of the situation: she fools him into thinking that she is his girlfriend and that Odd, Yumi and Jeremy are his sworn enemies… It’s a difficult situation, all the more so because the nano viruses are starting to affect the whole population! Luckily, our heroes can once again join forces on Lyoko and save the world from amnesia!

Killer Music

But Odd, left all by himself, goes into a strange trance-like state and stops moving… The next day, Odd, whose pulse is slowing down more and more, is admitted to hospital… and shortly afterwards, Sissi suffers the same fate. Afraid that this may be a X.A.N.A. attack, Jeremy and Ulrich rush to Lyoko, while Yumi, elsewhere, comes to realise that X.A.N.A. is getting people with the song !

While Odd and Jeremy rush to the laboratory, Yumi and Ulrich try to eliminate the robot which is hot on their tails. But things are not as easy as they seem: the Robot has destroyed the laboratory, which means that no one can get to Lyoko until it’s up and running again, and Aelita is in danger! What’s more, thanks to its artificial intelligence and reinforced armour, X.A.N.A.’s Robot seems indestructible. And Jeremy has to stay in the factory to fix the lab !

Still in doubt, Ulrich, Yumi and Odd are sent to the virtual universe and realise they have fallen into a trap. If they attempt to come back to the real world, they will be annihilated once and for all!

Synopsis by: Sophie Decroisette
Script by: Jean-Remi François & Bruno Merle

Our heroes are doing battle with Sissi who is acting very strangely. Could X.A.N.A. 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 X.A.N.A. (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…
