Amperling is the Ghouled version of the Tazerling. It has dark blue skin with a yellow belly and neon green lightning bolt-shaped antennae. They have electric powers like the Tazerling, but, like most Ghouls, they are stronger and more dangerous than their normal counterpart. Amperlings can be defeated using an Tazerling's Quetzabolt attack.
Known owners of the Amperling mainly used by Dr. Blakk and his employees.
