The Guardian possessed near-supernatural powers and strength. Among its arsenal was the ability to fire a concentrated superlaser, as well as the ability to modify its size and to teleport. After being released from its prison by curious Rebel archaeologists, the Guardian began to slaughter what it perceived as unwelcome intruders. Eventually, due to efforts by Rebels Luke Skywalker and Leia Organa and Imperials Wil'm Grau and Anarine, the ancient complex was smashed into disrepair, apparently killing the seemingly invincible monster.
