The Suicide Squad: Everything You Need To Know About Starro
4. He's Been A Member Of The Yellow And Red Lanterns
For decades, the Green Lantern Corps' Power Rings didn't work against anything that was yellow. Because Starro can change any colour, the intergalactic police force have great difficulty combatting the Star Conqueror. Sinestro knew this when he formed his own group, the Yellow Lanterns AKA the Sinestro Corps and so, had Starro join his ranks.
But that's not the only team Starro has allied with. In Injustice 2 #28-33, the Star Conqueror was welcomed into the rage-fuelled corps, the Red Lanterns. When his spores found a host, not only would they be under Starro's thrall, they would automatically be inducted into the Red Lanterns.
Within a matter of days, Starro had converted millions into hate-filled Red Lanterns, including Green Lanterns and one of the Guardians of the Universe.
The New God, Metron, believed the hateful properties of the Red Lanterns would corrupt Starro so much, he would inevitably consume all life within the universe. When fellow Green Lantern, Guy Gardner, learned this, the first thing he said was, "Well, this is pretty much the single worst thing imaginable."
Starro came very close to ending all reality as we know it before he was defeated by, of all people, Blue Beetle.
