Tynamo

Tynamo is a pure Electric-type Pokémon introduced in Generation V, hailing from the Unova region. Known as the EleFish Pokémon, Tynamo is a small, eel-like creature that is notable for being one of the few Pokémon with no gender differences and no abilities when caught in the wild, though its evolutions gain Levitate. Tynamo evolves into Eelektrik starting at level 39, which then evolves into Eelektross when exposed to a Thunder Stone. In the wild, Tynamo are typically found in large groups in the ocean's depths, where they generate electricity to communicate and deter predators. Their simple biology and powerful electrical capabilities make them fascinating subjects for study within the Pokémon world. Despite their small size, a chain of Tynamo can unleash a formidable electrical current, making them surprisingly dangerous in numbers. They play a minor role in the anime, often appearing as background Pokémon or in episodes featuring marine environments.
