A female Guardian has been left scarred by the Anti-Monitor, and the exposure to his antimatter energy reveals to have had dire consequences. Her fellow Guardians were unaware of the changes within her, either physical or behavioral (she is far more militant than is normal for the Guardians). In the "Origins and Omens" backup stories running through several DC releases in February 2009, she is given the official name of Scar. Scar killed one of her fellow guardians in the beginning of the Blackest Night, and is later revealed that she has since died after the Anti-Monitor's attack, and functions as an undead instead of an immortal. Another guardian was killed by Nekron, as a sacrifice to summon the Entity on Earth. The Guardians seemed extremely displeased with the appearance of the other corps. While they "tolerated" the existence of the Star Sapphires, they made it clear that they were going to exterminate the Red Lantern Corps. They also made a deal with Larfleeze of the Orange Lantern Corps some time ago, which resulted in the Vega System being out of Green Lantern jurisdiction. However, they seem to show particular displeasure with the Blue Lantern Corps, going so far as to attempt to forcibly remove the blue ring acquired by Hal Jordan, and when that didn't work, attempting to hold him on Oa until such time as it could be removed. With the ultimatum delivered by Larfleeze, the current wielder of the orange power of avarice, Scar proposed lifting the ban on the Vega System as well as having the Guardians leave Oa to get involved in the conflict personally. The Guardians accepted Scar's proposal and left Oa with Hal Jordan and the Green Lantern Corps to confront Larfleeze in the Vega System. The Guardians also decided to see how Jordan's blue ring would function with his green one during battles. After the Agent Orange's defeat, the Guardians negotiated with Larfleeze once more in order to continue to keep the orange light of avarice contained. The Agent Orange later launched an attack on Odym, seeking to possess the powers of the Blue Lantern Corps, presumably being swayed by Scar. During the "Blackest Night", the Guardians finally realized that Ganthet and Sayd were correct in their interpretation of the prophecy discovered by Abin Sur. However, Scar killed a Guardian and bound the rest to prevent them from interfering. She later sent a number of black power rings to the Green Lantern Corps' memorial, reviving the deceased members of the Corps as undead Black Lanterns.
