Energy Field is a special power that Aelita developed in Season 3. Using that attack, she can fire a ball of energy that can destroy a monster, even without hitting the Eye of XANA (the exception is a closed Megatank). Two energy fields combined in Aelita's hands can block any lasers from any monster and can slow down a Megatank's beam. And if they strike the Megatank's beam simultaneously, it shatters it like a piece of glass. In Skidbladnir she shows the ability to combine two energy fields into one huge one. When Aelita is a spectre, her energy fields seem to have more power than on Lyoko, as when she fought against the army of robots, one energy field caused a powerful explosion that destroyed several of the robots, whereas on Lyoko, her energy fields can only destroy one monster at a time.
