Tensei Shitara Slime Datta Ken is a Web Novel written by Fuse, and has since been adapted into a Light Novel, Manga, and Anime. The story follows a normal 37-year-old guy, Mikami Satoru, who after being stabbed and killed by a robber, finds himself reincarnated in another world as a blind slime with unique skills. With the new name "Rimuru Tempest" given to him after meeting his new friend, the "catastrophe level" Storm Dragon Veldora, he starts his slime life in another world, while on the way building a city for monsters and increasing his number of subordinates.

Note: The Web Novel and the Light Novel are different continuities with different stories and thus cannot be used to scale to each other. The Manga and Anime, due to being adaptations of the Light Novel, cannot be used to scale to the Web Novel.

Characters below Awakened Demon Lord level are usually around town level and subsonic to hypersonic+, while Awakened Demon Lords are capable of destroying entire continents and moving at relativistic+ speeds. Characters around the True Dragon tier are capable of generating supernovas, and black holes and moving at FTL speeds. With the strongest characters being capable of creating multiple universes.

Awakened Demon Lords are spiritual entities who will regenerate as long as their souls aren't destroyed and are capable of moving in stopped time. There are numerous hax abilities in the series like Soul Manipulation, Probability Manipulation, Fate Manipulation, Reality Warping, Time Manipulation, Intangibility, Causality Manipulation, Existence Erasure etc.

The god of the universe, Veldanava after being bored in complete nothingness, created the entire world which has several parallel universes, and all its rules and all abilities in the series.
