Dungeon Dominators

Dungeon Dominators (死を齎す迷宮の意思) 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, Ramiris, 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 Elemental and Holy Magic. Equipped with the Death Scythe (死神の鎌) and Hell Clothes (冥府の衣).
 * Skeleton Magic Knight: Veldora's avatar. An all-rounder warrior that has the potential to learn Magic. Equipped with the Death Bastard (死神の片手剣), Gate Shield (獄門の大盾) and Hell Mail (冥府の全身鎧).
 * Red Slime Assassin, Scarlet: Milim's avatar. Specializes in hit-and-run tactics using its overwhelming speed. Equipped with the Death Pickle (死神の一撃) and Crimson Cape (紅の羽衣).
 * Living Armor Berserker: Ramiris' avatar. Wielding a giant axe, it always charges head-first into enemies, acting as the team's tank. Equipped with the Death Axe (死神の大斧) and Heavy Full Plate (重厚な全身鎧).

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 let them roam the labyrinth on their own.
