Green Lantern Oath
Green Lantern is the name of several superheroes appearing in American comic books published by DC. The original version of the character created in 1940 by Martin Nodell with scripting or co-scripting of the first stories by Bill Finger during the Golden Age.
"In brightest day, in blackest night No evil shall escape my sight! Let those who worship evil's might Beware my power... Green Lantern's light!"
In issue #9 of the original Alan Scott Green Lantern comic book, scriptwriter Alfred Bester, best known as a major science fiction novelist of the 1950s introduced the Green Lantern Oaths.
"In brightest day, in darkest night No evil shall escape my sight! Let those who worship evil's might Beware my power ― Green Lantern's light!"
This oath was revived for the Hal Jordan version of the character. Alan Moore and Geoff Johns introduced variants. Oftentimes "darkest night" is changed to "blackest night", which inspired the name of the crossover event Blackest Night. In reference to the oath, the sequel to Blackest Night was called Brightest Day.
