 Don Hall (the original Dove) was immune to recruitment into the Black Lantern Corps as he was "at peace" which destroyed the Black Lantern Rings that attempted to recruit him.Another vulnerability of their rings power is that the odd physics behind magical power can dumbfound their abilities, as was the case when Arthur's daughter Serenity cast protection spells which disrupted the blackout effect of his power ring.In the Flashpoint universe, the successful murder of William Hand at the hands of the Red Lantern called Atrocitus freed Nekron from imprisonment long before several of the different colored Lantern Corps and the long-prophesied "War of Light" ever erupted across the Universe.
