Guardian — codelyoko

The Guardian is a unique monster created by X.A.N.A. tha captures and traps someone inside it rather than devirtualize them. Aelita described it as "a sort of digital jail adapted to the body imprisoned in it", with the person inside being stuck in suspended animation.

The Guardian appears to be completely indestructible. The only way to release a captured person from a Guardian is to "trick" it by creating a false copy of the prisoner next to the Guardian, causing it to reject its original (real) prisoner and move to the new (fake) one. This has been accomplished both with Jeremie creating a lifeless copy and with Aelita's Creativity.

Guardians have only appeared twice. The first time was in Image Problem, where it was used to capture Yumi so that X.A.N.A. Yumi could return to Earth in her place in order to destroy the Scanners so that Ulrich and Odd would suffer deletion upon being defeated by X.A.N.A.'s monsters.

The second time was in The Girl of the Dreams, where it was used to capture Aelita. This worked in a complicated plot in tandem with the transfer of Taelia. The Guardians never returned after the first season, possibly because X.A.N.A. realized how ineffective they were.
