Plasmatic energy is a type of energy associated with some subspace phenomena, including sporocystian lifeforms such as the Nacene. In 2372, the formation of a plasmatic energy field in main engineering aboard the USS Voyager preceded the appearance of Suspiria. (VOY: "Cold Fire") Plasmatic energy discharges are associated with astral eddies, such as those encountered by Voyager in 2373. (VOY: "Real Life")
