Origins Of 10 Different Lantern Corps And Their Oaths

Sinestro Corps are powered by the Yellow Light which represents fear, hence they are also known as the Yellow Lantern Corps. They function as a mirror organisation to that of the Green Lantern Corps and its members are handpicked by Sinestro from all around the universe.

All members are individuals who can instil great amount of fear and are powered by the Yellow Power Rings. They are considered to be the evil equivalent of the Green Lantern Corps and their direct rivals as well.

When Hal Jordan imprisoned Sinestro within the Central Power Battery on planet Oa, he used his Yellow Power Ring to awaken Parallax, a space parasite that is the embodiment of fear who was also imprisoned there, from hibernation. With this, Sinestro started to build his own Lantern Corps and began recruiting members from all around the Universe in secret and armed them with Yellow Power Rings.

Sinestro's objective was to enforce his own vision of order with fear throughout the Universe - a cause he once fought against as a Green Lantern.

Oath: "In blackest day, in brightest night, beware your fears made into light. Let those who try to stop what's right , burn like my power, Sinestro's might!"
