The Energy Slash is an incredibly strong and destructive attack that is used by X.A.N.A. William and at one point, Ulrich. This power is sword-related only, as an element of Ulrich's Katana and William's Zweihänder.

Ulrich only used it once in the episode "Franz Hopper", with the temporary modifications and upgrades added by X.A.N.A. Franz Hopper (who was thought to be the real Franz Hopper by the Lyoko Warriors). However, this ability was lost at the end of the episode, and for unknown reasons, Ulrich never told Jeremie about this stronger ability to his katana after this.

William used it first in Final Round to devirtualize others and destroy Core of Lyoko protective shields. He also uses it on a semi-regular basis throughout Season 4, Code Lyoko: Quest for Infinity, and Code Lyoko: Fall of X.A.N.A..

To generate this powerful attack, one must hold their sword tightly with both hands and begin charging power. This is usually done by holding it steadily as the power climbs the blade until it is glowing with a radiating aura. After this, a simple swing of the sword will unleash a powerful, energy-based disc that travels at high speed and seemingly infinite distance. One energy slash is powerful enough to instantly devirtualize any Lyoko Warrior if it connects. They also do massive damage to the shields of the Skidbladnir, leading to believe that it does more than 100 attack points of damage. Either way, if not avoided or deflected, it's a guaranteed one-hit knockout. There seems to be no drawback to using this technique aside from brief charging time, which X.A.N.A. had seemed to dispose of as part of William's upgrades for Season 4.

Very few things can counter the Energy Slash. Ulrich's katana has been observed to be able to dispatch them in "Final Round", but the impact of at least two swings could be sufficient enough to leave him vulnerable. In "Canine Conundrum", it is revealed that Aelita's Energy Fields have the unique defensive capability of completely halting and absorbing this attack when two of them are used together as a shield.
