Imagine waking up and finding these eating your car battery like a buncha hagfish

Pokedex Entry

Sercuit - they snap onto their own tail to keep their maw charged and ready in case of predators or potential prey. Typically found near cities, they like to congregate around power grids and nibble on the structures. Some cities station trainers with ground type Pokemon to protect the grid from frequent infestations.

Voltangle - Although bound together, the two serpents still only chase their own tails. The two heads think independently and frequently beef with one another, especially over food. However, in the few rare moments the two heads do come together to work as one they can be unstoppable.

Dynagnarl - in contrast to the discordant knot of its previous form, this Pokemon's multiple minds have learned to work together in perfect synchrony. Their cooperation is evident with the sophisticated body the four serpents manage to maintain despite being individual creatures. They are known to climb mountains during thunder storms to absorb the energy from lightning strikes.
