Greeghan was the military leader tasked by the Gordanian leadership to start the invasion on Thanagar during the ensuing Thanagarian-Gordanian War. Leading a fleet of 20 ships, he was ruthless in his quest to finally defeat the Thanagarians, killing all of Hro Talak's fleet outside of himself so he could send a message to the rest of Thanagar.

Even though he did well in his quest, the reckless attitude of one of his fleet's captains, Tskalikin, who attempted to mutiny and gain credit for besting the Thanagarian forces. This led to an ensuing morale conflict between the Gordanians.

After Hawkgirl was able to destroy Tsakilin and his loyalists with the help of Talak's sacrifice, she, alongside the Justice League, went to Greeghan's weakened ship and gave him an ultimatum; declare peace between Thanagarians and Gordanians and never return to their planet in search of Nth. He unwillingly agreed, cessated fire, and ordered his forces to return to Karna.
