Green Lantern Hal Jordan is overwhelmed by the superior numbers of the Manhunters. Throwing a hail mary, Hal sent out broadcast to all Green Lanterns in hiding asking for their help. He told everyone that the Green Lantern main battery still exists and is hidden in Oa, and by freeing it from the Mahunters control everyone would get a power boost. Luckily, a lot of Lanterns answered the call just in the nick of time.
