The Blue Lanterns or Blue Lantern Corps were, in an alternate reality, a group of powerful beings who utilized a facet of the colored energy spectrum wielded by the ancient Oan civilization, who were proclaimed as the Guardians of the Universe.
History and specificsEdit
In variations of this particular reality, the Blue Lanterns drew energy and used the emotion of hope to focus this energy through individual power rings. The blue light energy required the user to utilize such emotional states to focus this spectrum's facet of primordial source energy from the origin of that multiverse, through Blue Lantern power rings.
