White Lantern Power Battery

Caelan's White Lantern Power Battery was formed at the end of The Blackest Night in the war against the Black Lantern Corps. In order to defeat Nekron, Hal Jordan redistributed the power of the Life Entity amongst various resurrected superheroes thus turning them into the White Lantern Corps. Their power was crucial in defeating Nekron and ending the Blackest Night Prophecy. However, shortly afterwards, the Life Entity disappeared and its energy surged into the sky where it coalesced into a White Lantern Power Battery on Dimension 42's Earth. The abilities of the White Lantern seem to be directly opposite to those of the Black Lantern, as to bring the dead back to life, even bringing the Black Lanterns back to normal. The godlike abilities of the White Lantern seem almost limitless.
