Energy Fields are Aelita's main weapon on Lyoko; though it acts more as a superpower rather than a physical weapon.


Season Three

At the beginning of the third season (which is set two weeks after Season 2), Aelita displays the ability to produce orbs of deep pink energy in her hands and fire them at enemies. However, Aelita does not have an affinity for combat, and thus this power is most often used defensively. Energy Fields are also quite slow for long-range weapons, and can be dodged rather easily. That being said, Energy Fields are arguably the strongest weapon of any of the Lyoko Warriors, being able to defeat any monster or avatar in a maximum of two hits; such breaking a Megatank's energy wall attack. For defense, Aelita may combine two Energy Fields into a small, oval-shaped barrier capable of absorbing standard laser fire. Aelita acquired the ability to use Energy Fields some time between the second and third seasons, having secretly programmed them into her avatar between semester break.

Season Four

Aelita is able to form Energy Fields in her hands at will, after which she may aim and fire them at a target. When first gaining the ability, it is shown that it takes several seconds of focus to summon the Energy Fields and project them much faster. She may also increase their speed or curve their trajectory by swinging her arm in a throwing motion while firing them. Though usually able to fire from either hand independently, Aelita may also use both hands at the same time to create an especially large Energy Field that can devirtualize anything in a single hit, though firing a much larger Energy Field leave her fatigued. She is only seen using this particularly advanced skill in "Skidbladnir."

As seen in "Replika", energy fields can be used in conjunction with creativity; capable of erecting an unusually strong force-field wall of deep pink energy. It is capable of withstanding extensive damage from both two Megatanks and William's sword until shattering into glass shards.

As a specter in the real world, the energy fields are beach ball-sized orbs of yellowish-orange electrical energy, whose shield can take on the shape of a dome around herself for defense. It takes one single energy field to wipe out several of X.A.N.A's robot army; an ever greater ability that is not possible on Lyoko.

Season Five

One year later, her energy fields are now capable of expanding her force-field to an ever larger one, which is capable of defending several people at once; which she used in "Countdown" to defend herself and Ulrich against a massive wall of Bloks, which tired her out. They appeared to be ineffective against the Blok wall.

In "Espionage," she once used them to create a blinding white light to distract the two Ninjas, even though the effect had devirtualized Ulrich.


Energy Fields are hollow orbs of deep pink, plasma-like energy that form in the palms of Aelita's hands. As they fly through the air, the Energy Fields discharge a trail of pink, transparent matter, and when they make contact with something, the target appears to be shocked with pink electricity. While usually about the size of a dodge-ball, Aelita's giant Energy Fields are roughly as large as an exercise ball.

When Aelita is a spectre on Earth, her Energy Fields appeared the size of beach balls and as yellowish orange orbs of electricity, which also expand to a dome-shaped shield.
