Pyrodine
From Tardis Wiki, the free Doctor Who reference
Pyrodines were fire-like creatures released from gaslights by a proto-morphic lifeform under the command of Morjanus. Morjanus created them primarily because they were immune to psychic attacks. Morjanus' people were fighting the Hunters, a psychic species, so this was a treasured attribute.
They killed a policeman called Bates. Morjanus intended they should burn the city to the ground, but they disappeared when the proto-morphic life form was destroyed by the Eighth Doctor. (DWM: The Curious Tale of Spring-Heeled Jack)
