Lightning Demons were hostile creatures native to the Demon Dimension. They were tall and thin, with grey or dark, purplish bodies. In place of hands they had large pinchers that conducted electricity. They could discharge this offensively both in melee attacks and by firing ranged attacks. They were very fast and would often attack in groups.
Cenobites of Avernus summoned them as their mistress, Azimuth, descended into madness and turned her wrath on the city. They were fought by the time traveling Raziel and Kain, their pack tactics making them formidable opponents.
When Kain was blasted into the Demon Dimension by Raziel, these were the first demons he encountered after being mocked by the disembodied voices of a group of Hylden, suggesting that these demons might have served or worked with the Hylden.
