An activated tower in the Mountain Sector in Code Lyoko: Evolution
|First appearance||X.A.N.A. Awakens (chronologically), Teddygozilla (production-wise)|
|Purpose||Attacks on Earth (X.A.N.A.), various programs, deleting sectors, teleportation, extra power for the Skid (Jeremie), creating polymorphic specters|
Towers are variously tall, cylinder-shaped structures located on the virtual world of Lyoko. They can be "activated" by various parties and used to harness the true, tremendous strength and power of the Supercomputer. There are ten towers in total located in each sector; excluding the Carthage region which has only one, two as of "X.A.N.A. 2.0;" the Cortex, which has at least one; and the Volcano Sector, who's number isn't documented and can be counted either way.
Every time X.A.N.A. attacks, he activates a tower and uses the connection to the real world to launch an attack. These attacks range from various things, however, the point is to prevent the Lyoko Warriors from accessing Lyoko and the Factory.
The core purpose of the towers is to tap into the true power(s) of the Supercomputer. Simple programs like monsters and the Superscan don't require actual quantum computing power and run without an activated tower. But programs such as the polymorphic spectre Jeremie and for example a program for reinforcing the Skidbladnir's shielding require an extreme amount of computing power. A tower is activated so that extra power can be harnessed.
There have been several occasions in which Jeremie or Aelita activated a tower for their own programs. But part of the program/operation appears to be a firewall or encryption algorithm to prevent anybody from interfering. When X.A.N.A. activates a tower, the only one with the power to deactivate it, is Aelita, using one of the Codes. When Jeremie activates a program, he often mostly prays that X.A.N.A. simply doesn't try to hack the tower and infect/corrupt the program. That proves that X.A.N.A. is the better programmer between it and Jeremie.
They were created by Franz Hopper for a less sinister purpose. As a computer scientist, he needed a stable way to tap into the computer's resources. Also, they serve as transportation throughout Lyoko. Towers are located in all the sectors of Lyoko. They are surrounded by various glows depending on who's currently using them.
- Red - The tower is under X.A.N.A.'s control. As of season 4, the only ones who can deactivate this is Aelita, or Franz Hopper, or X.A.N.A. himself. In season 5, Odd, Yumi, and Ulrich gained this ability.
- Teal - The tower is a Way tower. Through these, X.A.N.A. can wipe out entire sectors with Code X.A.N.A.
- White - The tower is activated by Franz Hopper. However, in later seasons this color also represents inactive towers.
- Green - The tower is under the Supercomputer's control. It is possible for X.A.N.A. to corrupt these towers while in use, however this technique has only been demonstrated a few times.
- Blue - The tower is inactive. In earlier seasons, this color also meant that Aelita was currently inside or contacting Jeremie. However, this color has been phased out in later seasons.
Just like all roads lead to Rome, all towers lead to Carthage via greyish wires that connect them all. If these wires are destroyed, the Tower is isolated from the rest of the system. They can be forcibly shut down by damaging them; this has only been done by X.A.N.A. two times, once in Code: Earth and again in Contact. Towers were, in Seasons One and Two, also the only place where Aelita could materialize from. Members of Team Lyoko that enter a tower will get all their life points replenished.
In Season 4, It is shown that William has the ability to place towers under X.A.N.A.'s control by entering the XANA code into the tower interface; he did this on the Replika to break the team's connection to the real world.
In season 5, It was revealed that Aelita needs to calm herself down before entering the tower. Ulrich, Odd and Yumi can also use towers now but if XANAs spectres manages to steal too much of their source codes, Towers might not recognize who is using it as in case of Odd who had lost all his source codes, but later regained some of his source codes in episode 19 of Code Lyoko Evolution, when Jeremy devises a plot to trap a spectre into one of the virtulizing machines to steal some codes for it. Sadly, the plan backfires when the spectre materializes itself into the Lyoko world as a cloud of green data bits, and it knocks out Yumi and Ulrich, which stil have codes, and tries to bring them into the numeric sea. Then Odd enters a Way Tower and Jeremy injects the code they stole from the spectre into Odd, and Odd deactivates the tower, destroying the spectre.
Number of TowersEdit
The number of towers has fluxuated throughout the show.
Initially, there were either 40 or 41, 10 for each sector, with a possible remainder for Carthage. The Carthage one was first shown in "Franz Hopper" which garanteed the total at 41. Later, in "Lyoko Minus One," the Forest Sector was deleted, lowering the total to 31. This was further reduced to 21 in "The Pretender," with the loss of the Desert Sector. Later, it was reduced to 11 in "Sabotage," with the team deleting the Ice Sector. The total dropped to one in "Double Trouble," with the loss of the mountain sector. When X.A.N.A. William destroyed the core, it dropped to 0. The total incremented to 1 with the recreation of Carthage, and later to 41 with the recreation of the rest of Lyoko, not counting towers within the Replikas. It dropped down to 21 between seasons 4 and 5, with the loss of the Forest and Ice sectors, and went up to 22 with the new tower in "X.A.N.A. 2.0," not counting the Cortex, which has an unknown tower count.
These numbers are turbulent depending upon how one counts the Volcano Sector.
According to the DVDs, each of the towers are numbered and in a specific location. Since there seems to be no specific pattern to their order, the numbers of the other towers cannot be extrapolated from the numbers given. These are the locations of the towers given on the third DVD, X.A.N.A. Possessed.

- Apparently Towers do not have a fixed position, they always seem to be in a new position every time they are visited, for example: the Way Tower that Aelita almost entered to destroy the Ice Barrier sector in The Secret was in an ice crater, but in Sabotage the Ice Barrier way Tower seemed to be in an open landscape. However each sector has two way towers so those two towers could have been two different towers. Some towers do tend to move. For instance, one tower in the ice sector appear on top of a plateau. The next time they visited it, it was under it and later appearing in the water not too far away.
- It seems that vehicles are not restricted to outside of towers, as demonstrated by Odd and Ulrich entering a Tower on the Overbike or Yumi and Aelita on the Overwing.
- In Cold Sweat, in order to recover the subroutines that shackled William to X.A.N.A., Aelita downloads information from the tower before deactivating it.
- It is shown by Odd that one can enter a tower from the upper side on a vehicle.
- The design of the tower in Code Lyoko: Evolution is completely different from the original show. Instead of a cylinder shaped tower there are now square pillars.
- Despite the new square pillar shape of the towers, their insides and internal platforms remain cylindrical.
- In the Social Game, both towers that Jeremie and X.A.N.A. activate are red, and deactivated towers are green from Jeremie's panel but have no colour in Lyoko.
- Blue and white towers are also absent there.
