Hro Talak dispatched Hawkgirl on a secret mission to study Earth's defenses. Five years later, Talak led his Thanagarian forces to invade Earth, under the pretense of strengthening the planet's defenses against a supposedly imminent Gordanian attack. Under his command, the Thanagarians started to build an apparatus, which was supposed to project a protective force shield around the planet. However, the machine was in reality a means to turn Earth into a link in a chain of several hyperspace bypasses, which would allow the Thanagarians to penetrate the Gordanians' defense system and wipe them out permanently. Hro Talak overrode the planet's defense systems, imposed Martial Law and enlisted forced human labor to finish the contraption.
Talak was betrothed to Hawkgirl, who aided him until she found out that such approach would result in the destruction of Earth. After Hawkgirl was arrested for treason, Hro Talak confronted her about her feelings for him. He pleaded her to renounce any feeling she might have had for John Stewart and admit she loved him instead. However, Hawkgirl simply offered herself in exchange for the safety of Earth. Enraged, Hro Talak spurned her and carried on with his plan, thinking that she might forget the Green Lantern once Earth was destroyed. When John attempted to deactivate the force field guarding the generator bypass, Talak engaged him.
Hro Talak is a well trained warrior, whose Nth metal ax makes him a magnificent opponent. He managed to destroy John's Power Ring, and nearly killed him, if not for Hawkgirl stepping in on time. Talak fought her off, and finally put his feelings for Hawkgirl behind him. John then provoked Talak, tricking him into destroying the force field that protected the deactivation switch. After the generator bypass was destroyed, Hro Talak declared defeat and retreated from Earth.
Fall of Thanagar
Upon returning to Thanagar, he discovered that the Gordanians had attacked and, with the fleets off waiting for his orders to attack the Gordainan Homeworld, the battle was over, and Thanagar had fallen. Nevertheless, Hro Talak relentlessly engaged and destroyed a dozen Gordanian Battleships. However, his entire fleet was destroyed, so he sent Paran Dul, Kragger and a few warriors to flee for safety in a scout ship. Finally, Hro Talak sacrificed himself, flying his ship on a suicide run to destroy the Gordanian flagship. His ship hit the Gordanian ship's weapons emmitter just as it fired, and the resulting explosion destroyed both ships.
PersonalityHro Talak didn't look at ethics to protect his people, and was willing to sacrifice an entire planet in the process. This coldhearted fixation to defeat the Gordanians resulted from Hro Talak having been captured and tortured by the Gordanians at one point, leaving him physically and physiologically scarred.
Originally, Hro Talak was intended to be Katar Hol, the DC Silver Age Hawkman. However, the creative team feared that fans might reject the idea of Hawkman being a villain. Therefore, they decided to created a new character based on the original one (note how "Hro Talak" is an anagram of "Katar Hol").
Talak may also be based on Fel Andar, a villainous Thanagarian who posed as Hawkman to gain the trust of the Justice League.
