Dungeon Dominators

Dungeon Dominators (ダンジョン・ドミネーター) are a group of monsters created by Rimuru to have fun and sabotage adventurers challenging The Dungeon. They serve as controllable avatars of Rimuru, Milim, Lamrys, and Veldora, which are inhabited using Pseudo Souls, played in a manner similar to an MMORPG. These monsters are:


 * Ghost Wizard: Rimuru's avatar. It is immune to physical attack, and is able to use both element and holy magic.
 * Red Slime Assassin: Milim's avatar. Specializes in hit-and-run tactics using its overwhelming speed.
 * Skeleton Magic Knight: Veldora's avatar. An all-rounder warrior that has the potential to learn magic.
 * Living Armor Berserker: Lamrys' avatar. Wielding a giant axe, it always charges head-first into enemies, acting as the team's tank.

These monsters are armed with Unique grade equipment created by Kurobe, and were initially created to sabotage the "Green Fury" team making advance in the labyrinth using questionable tactics. After their success, they were having a lot of fun eliminating adventurers and challenging the labyrinth itself, becoming the infamous menace known as "Dungeon Dominators" among adventurers.

Later in the story, Milim's pet dragon Gaia joined the party. When not controlling these avatars, they will set them into auto-mode and roam the labyrinth on their own.
