White Lantern Corps

The White Lantern Corps first appeared in Blackest Night #7 and was created by Geoff Johns and Ivan Reis.

After being resurrected, Black Hand generates twelve white rings that revive Martian Manhunter, Aquaman, Deadman, Hawkman, Hawkgirl, Jade, Firestorm (Ronnie Raymond), Osiris, Hawk, Maxwell Lord, Captain Boomerang, and Professor Zoom.

[3][4] The Entity tells the resurrected that they must complete certain tasks to be fully restored, and instructs Deadman to find a new guardian for it.

The original wielder of the Entity, Sinestro, displays the ability to eradicate swarms of Black Lanterns effortlessly and is described as "godlike".

[20] When Hal Jordan wields the power, he demonstrates the ability to create additional rings and restore heroes claimed by Nekron to life.

[16] This white ring was unable to perform the resurrection of a planet's worth of beings that had died all at once, but it has not yet been tested on an individual basis to determine if this is a limitation of function or simply scope;[17] Kyle claimed that he can only heal rather than raise the dead, but this may be an assumption rather than a fact.

[22][23][24][25] As the sole White Lantern, Kyle Rayner briefly had the Life Equation within his ring and could use the power of the entire spectrum.
