Origins Of 10 Different Lantern Corps And Their Oaths
2. White Lantern Corps
The White Lantern Corps are pretty much the antithesis of the Black Lantern Corps. The White Light is the first light and all the other colours of the Emotional Spectrum are derived from it. This allows the wearer of the White Ring to generate any of the other colours of the spectrum and use each of their powers, making the wearer one of the most powerful beings in existence.
The White Lantern Corps appeared near the end of the Blackest Night when Hal Jordan allowed the Entity, an ancient creature responsible for the creation of all life in the DC universe, to possess him. This converted his Green Lantern Power Ring into a White Lantern Power Ring.
Hal Jordan then gave other heroes White Lantern Rings and together they ended the Blackest Night and defeated Necron. Soon after, the Entity vanished, putting an end to the White Lantern Corps.
Oath: "In brightest day , in darkest night, let my ring shine the brightest light. When evil comes, I will join the fight, the power of the White Lanterns, is the strongest might!"
