Cyber slimes have slightly rounder bodies than their ordinary cousins and have a dark grey metallic body similar to that of a Metal slime. On the left side of their body, their ocular implant consists of a metallic faceplate with electrical wiring covering their left eye that has been attached with screws, giving the Slime a robotic red eye. Its bestiary descriptions state that the Cyber slime has oil circulating throughout its body instead of blood and its cybernetic implants have enhanced its agility and durability. In battle, it is capable of generating powerful electrical shocks against enemies.
Cyber slimes make their debut in the main series starting in Version 3.0. They are capable of attacking with Lightning and can even cast Kazapple. Although their magical might is low, they can quickly overwhelm the player, especially if multiple Cyber slimes gather.
These slimes have modified their bodies in emulation of the idol, the metal slime. Be warned――they can short their own circuits in order to shoot powerful lightning blasts.
Cyber slime appears as a B-rank monster of the Slime family that can be scouted normally from any banner. It can participate in the Battle Roads of the Slime knight, Mjoll, and the Mindini hunter as a party member.
