Glaster is a Space Beast used by the Hades Army and an antagonist in episode 31 of Genseishin Justirisers.
History[]
As Kaiser Hades began preparations for his final plan to destroy Earth using the Magnecrusher, he summoned Glaster to Earth in order to use it to take out RiseRoss. Glaster arrived on Earth in a meteorite before rampaging once it landed. In response, the Justirisers summoned RiseRoss and piloted it to battle Glaster. RiseRoss initially seemed to gain the upper hand against Glaster until Glaster grabbed RiseRoss and revealed its secret ability to petrify things. Glaster incapacitated RiseRoss before exploding to turn it completely to stone, forcing the Justirisers to exit it.
