PZW- (or Plasma ZEXAL Weapons, or simply Plasma ZWs) is a sub-category of "ZW" monsters that activate their effects while they become Xyz Materials on a "Utopia" monster BUT they cannot be activated if, except this card, there is an Xyz Monster on the same Xyz Monster as an Xyz Material. So, only 1 PZW- monster can be as an Xyz Material of a "Utopia" monster. They are named after modern weapons, weapons in science fiction or futuristic weapons and an animal. They are created with Shining Draw when Yuma Tsukumo and Astral created ZEXAL III.
