Sirket is a bleedbug, an insect that lives in the space between dimensions. How it came to reside is unknown, though many have speculated that the Anti-Monitor brought it to experiment on it. When Sirket rubs its massive front legs together, the sound it makes can drive men mad. Sirket was present when Kyle Rayner was captured and abducted to Qward. He would later participate in the Battle for Mogo where he came into conflict with the Green Lanterns, Barreer Wot and Lok Neboora.
