The Slizer Universe is the place where all of the galaxies and planets in the Slizer storyline are.
At the creation of time the ancient ones who created the universe decided to make one with war machine robots. They took all of their power and created planets such as the Slizer Planet, Lenon 3, Dranee 5, and Troda 9 along with many other planets. They also created special elemants for the Slizer Planet's regions. Those include Fire, Ice, Jungle, Energy, Rock, Water, and Judgement. They have since been ruling the universe while giving their minions orders to destroy the Slizers. Slizer Drones are used in this universe. They are typically used by Slizers.
