Guardians are the only of Xana's monsters that doesn't have an eye and can't be struck to destroy it.This is the only monster in Xana's army not based on a real living creature besides the transport orb.

• Height: 6 feet 2 inches
• Weight: 200 lbs.

Guardians looking like giant orange bubbles the encase and disable a person. The only way possible to defeat a Guardian is to create a false version of the captured person and place it next to the guardian so to confuse it into accepting that the person it has is not the real one and the false one is, usually the false is also a bomb which is then detonated when the guardian rejects and expels the real person. The only warriors who were captured by the guardians was Yumi in the episode "Image Problem" and Aelita in the episode "The Girl of the Dreams." Both of these attacks were in season 1 but the guardians never returned in seasons after that, possibly because XANA realised how in-effective they were.
