Procanon Kaa has been a Green Lantern for generations. Stubborn and headstrong, he has made a career mediating fights within the Khund empire, a job that has made him many enemies. Several Khundish warlords have labelled him an enemy of the empire and have tried to ban him from many of the planets within his sector. This animosity has since spilled over with tragic results when, during a Khund attack on his homeworld, Procanon Kaa's daughter was killed.
