Eel

Electric Eel (電気ウナギ) is a Quirk used by Teruo Unagisawa.

Description
Under the effects of Trigger, this Quirk transforms Teruo into a large, eel-like creature with incredibly slimy skin. Upon being kidnapped and modified, Teruo's arms and legs bulk up and Teruo can discharge a surge of electricity, which then causes him to pass out. When used by Tamao Oguro and Kuin Hachisuka through a sample collected from Teruo, she is able to emit electricity from her fingers.
