Additionally, White Lanterns possess an incredible healing factor, with Sinestro recovering from a mortal wound inflicted by Nekron in a matter of seconds, an ability which can be used to heal others. Tapping into the Entity's power, White Lanterns can resurrect the dead, including restoring life to barren landscapes. Like most Lantern Corps, White Lanterns can create energy constructs powered by life itself.

When channeling the power of the Living Entity through the White Lantern power ring, a ring bearer gains a degree of omnipotence. After Nekron's defeat, the White Lantern unexpectedly resurrected Deadman, Martian Manhunter, Aquaman, Jade, Hawkman, Hawkgirl, Maxwell Lord, Eobard Thawne, Hawk, Ronnie Raymond, Osiris and Captain Boomerang for unknown reasons. Hal Jordan seized the opportunity to bond with the Entity and use his newfound powers as a White Lantern to restore Superman, Wonder Woman, Green Arrow, Donna Troy, Bart Allen, Animal Man, Superboy, and Ice to life as White Lanterns and they had been transformed into Black Lanterns by Nekron.

This transformation was short-lived, however, with Nekron forcibly removing the Entity from Sinestro when the two battled briefly. Bonding with the Entity, Sinestro transformed into a White Lantern with the entire power of life itself at his disposal. The first White Lantern was Sinestro, leader of his eponymous Sinestro Corps wielding fear-powered rings. It housed an omnipotent creature, the Life Entity, who is connected to every living thing in the DCU and under attack from Nekron, the undead embodiment of death and leader of the Black Lantern Corps. At the end of the comic book crossover, a massive White Lantern was unearthed. The existence of a white energy within the DCU's emotional spectrum was teased over the course of Blackest Night when another Lantern combined their energy with that of a Green Lantern to create a white energy blast to destroy a Black Lantern ring.
