Pokedex Entry: “This Variation of Jolteon breaks it’s body down into electric particles to hide in wiring and electrical lines among towns and cities. It feasts off the electricity found there and won’t stop eating until it’s full. Often the result of power outages will be because a pack of Black Light Jolteon will have eaten their fill at a local power plant. When in the physical realm, this pokemon can only be visible under a Black Light.”
