Hawkman's most distinguishing features are the giant wings on his back and his heavy armor. He wears a black cuirass with a hawk logo in a red circle in the middle. His belt, spaulders, greaves and gauntlets are golden. He also dons a golden helmet with a beak shaped front and outstanding wings on top.
His primary weapon is a large spiked macemade of Nth metal.
Hawkman and Hawkwoman started operating as heroes in 2004,and were inducted in the Justice League in 2004.
Hawkman watched as Hawkwoman and the other Leaguers were found guilty of all charges and taken away. Superboy, Miss Martian and Adam Strange arrived in court, with new evidence. Hawkman was present when the Tribunal heard the evidence, and waited with Icon, Conner, M'gann and Adam while the court deliberated. Eventually, the Tribune announced the charges against the Leaguers were dropped and they were released from custody.
Rimbor June 20, post-00:16UTC
As Hawkman and the other Leaguers walked the streets of Rimbor, ready to return to Earth, Vandal Savage broadcast a message through holographic monitors, declaring Earth off limits to alien invasion. Superman was skeptical about Savage's threat, but then Batman pointed to a giant satellite, the Warworld, passing through Rimbor.
The League finally arrived at Mount Justice, Hawkman among them. The mountain was in ruins, and Superman wondered whether they were already too late in dealing with the invasion that embroiled the Earth before and during their absence. Members of the Team descended from the heavens, acting as a welcoming committee. Batman asked Aqualad, who in their last meeting was still a traitor, what happened there. Aqualad reassured them that the crisis has passed, but not without loss.
Hawkman was first imagined in 1940 as egyptologist Carter Hall. In the Silver Age, he was reimagined as a Thanagarian law enforcement officer named Katar Hol; Young Justice's Hawkman is based on the latter version.
Though Hawkman has had five appearances in animation, he was only identified as the Thanagarian Katar Hol thrice: in Hanna-Barbara's Super Friends, in Filmation's Superman/Aquaman Hour of Adventure, and in the last season of The Batman.
