Eelektross (Japanese: シビルドン Shibirudon) is an Electric-type Pokémon. It evolves from Eelektrik when exposed to a Thunder Stone. It is the final form of Tynamo.
Eelektross is an eel-like Pokémon that resembles a lamprey, with a long tentacle-like, finned limb extending from its head. It has red eyes, dark blue body, and, unlike its earlier evolutions, possesses clawed, paddle-like arms with yellow spots and yellow-and-red palms. It has a beige fin on the upper portion of its body and beige fin-like legs below.
