Seeing is Believing is the second episode of Code: LYOKO. It aired on April 20, 2004. It was included in the DVD set Movies, Music, and Mayhem.


The episode starts with the Chief Engineer at the local nuclear power plant giving a lecture on the basic operations and safety measures of the power plant to a class at Kadic. Most of the students find the lecture boring and aren't paying much attention to it, but Jeremie asks him if there is a process for using virtual particles and materialising them in the real world. Odd and Ulrich look at Jeremie knowingly (they know that he is searching for a way to bring Aelita to Earth) but the scientist tells him that it's only in the realm of science fiction. Mrs. Hertz then comments that Jeremie is "an excellent student, but a bit of a dreamer", which causes the other students to laugh at him. Suddenly, the power to the projector goes out. Mrs. Hertz assumes that it is just a blown fuse.

After class, Yumi meets up with Jeremie and the others. Jeremie thinks thst XANA may have something to do with the projector, but Odd says that it was just a short circuit. Mr. Delmas then comes up to Odd and tells him that he will allow Odd to form his group, the Pop Rock Progressives (although Mr. Delmas accidentally called the group the "Foxtrot Fanatics") as long as he allows anyone to try out for it. Odd is very enthusiastic and wants to make copies of the leaflets about the Pop Rock Progressives right away, but Jeremie would rather check out the power outage. Jeremie goes to his room and starts to look for signs of trouble on his computer. He tells Aelita about the school's electrical problems and asks her if anything is going on at Lyoko. She says no, but Jeremie starts a scan for an activated tower anyway before heading off to the cafeteria.

Meanwhile, Odd is handing out leaflets for his group, even giving one to Jim. However, he refuses to give one to Nicholas when he reaches for one. Later, Odd is trying to decide what he wants from the vending machine. He comments that the soup tastes like dishwater, so Ulrich quickly pushes the button for soup. However, the machine only manages to pour a few drops before quitting. Jeremie thinks that it may be another power failure and decides to keep checking for problems while the others go to the Gym to hold auditions.

In the Gym, Emmanuel tries out for drummer, but Odd doesn't like his heavy metal rhythm. Naomi then shows up to try out for drummer. She is obviously very new at it, but Odd (apparently attracted to her) likes her performance anyway. Meanwhile, Jeremie finds out on his computer that 400,000 volts are circulating in a high-tension pylon. He is about to tell Aelita about it when the power in his room goes out. Jeremie runs outside where he catches a glimpse at the pylon, which is surging with electricity. He heads to the Gym and tells the others that XANA has to be involved because the pylon is way over its voltage limit and could explode. They are trying to figure out why XANA would do something like that when Sissi and her gang walk in to insult Team Lyoko ask that Nicholas be allowed to try out for drummer.

Jeremie runs off to the Factory while Nicholas plays the drums with far more skill then Naomi and impresses Odd, Ulrich, and Yumi. Sissi's Gang leaves but Odd still doesn't want him in the band, no matter how good he is. Odd (the guitarist) threatens to leave the band if Nicholas is allowed to join, while Yumi (the singer) threatens to leave the band if he isn't allowed to join. Just then, Jim walks in playing a trombone and (much to the group's surprise) asks if they need a trombone in the band.

Meanwhile, Jeremie has arrived at the factory, where Aelita confirms that XANA has woken up. She heads to the desert to find the tower while Jeremie finds out something bad and interrupts Jim's audition by calling the others to come to the factory. Once they arrive, he tells them that XANA's plan is to gather enough voltage in the pylon so that he can unleash it all at once at the Nuclear Power plant. Meanwhile, the pylon is raining sparks and an electrician calls in to say that he can't cut the power for some reason.

Back in the factory, Jeremie says that XANA will be able to blow everything up once the pylon reaches one million volts. Yumi is worried because nuclear sabotage is something that is way over their heads, the whole region would be wiped out if they fail on Lyoko! She wants to warn the authorities but Jeremie is worried that the authorities will shut down Lyoko (and thus, Aelita) for good once they find out about XANA. Yumi knows this, but she doesn't want to risk a nuclear disaster. Jeremie decides that they will vote on it. Yumi and Ulrich want to raise the alarm while Jeremie and Odd don't, making it a tie. Jeremie and Yumi start to argue about which of the two courses of action they should follow because of the tie when Aelita (who was listening all along) asks if she has the right to vote too. Jeremie tells her that she does, but she votes to tell everyone because she doesn't want to risk thousands of deaths just to save herself. In the end, they agree that Ulrich and Odd should go to Lyoko, while Yumi should go off to tell the authorities.

Yumi bursts in on a meeting between Mr. Delmas, Mrs. Hertz, and the engineer from the power plant to tell them that the plant is in danger of blowing up. Meanwhile, Odd, Ulrich, and Aelita arrive at an oaisis near the tower, but they can't find the tower. Yumi calls in to say that nobody believed her. Jeremie responds by saying that the pylon is 85% charged and that they can't find the tower.

On Lyoko everyone is sitting around the oasis nervously. Odd throws a rock into the water and it shines instead of rippling. He then figures out that there isn't any water down there and goes into the "pool" for a better look. The others follow him and, sure enough, they land within sight of the tower. The tower is guarded by three crabs. One of them chases after Aelita as she runs away. Odd blocks its fire with his own body and is devirtualized. Ulrich defeats one, but the pylon is up to 95%.

Meanwhile, Yumi repeats her story to the electricians near the pylon and they almost seem to believe her, but then they ask her how she knows what will happen. Ulrich defeats the other two crabs with triplicate. Yumi still can't get anyone to believe her anout the supercomputer and Lyoko as Aelita enters the tower. The pylon reaches 100% and XANA launches the energy at the power plant, but Aelita deactivates the tower at the last moment and Jeremie activates a time reversion.

After the time reversion, the Pop Rock Progressives (with Odd on guitar, Nicholas on the drums, Ulrich on keyboard, Yumi on the mike and Jim on trombone) perform a song called Mystery Girl, which is really about Aelita. Jeremie comments that their energy is "super nuclear" and will "make the town explode". With that, the episode ends.


  • In the Theme Song Intro Yumi's book is light blue, however in the episode it is red.
  • The fire officer's voice sounds like William, who had not yet been introduced.
  • More scenes from this episode are used in the season 1 tiltle sequence than any other episode.
  • Jeremie's screen shows that there are still three Krabs after Ulrich and his clones killed two of them
