Lois later returns as a sinister Black Lantern with her husband in the "Blackest Night" crossover. Her first task is to kidnap Martha Kent with her spouse, and stating that she and Kal-L wish for Kal-El, Connor Kent, and Martha, to be reunited with Jonathan Kent in death. She proved unable to deal with the resourcefulness of Martha Kent, and was set ablaze by the widow, but kept regenerating until Krypto intervened, ripping the black ring out of her hand and preventing regeneration for long enough to allow Superman and Conner Kent to destroy the Black Lantern powerhouses attacking Smallville, and reaching town to aid others unhindered.
