An archaeologist and lion hunter, Edward Dawson found a mystical artifact called Mithra Meteor and was the first who was turned into Lion-Mane, an avatar of alien race. He retained his mind, but as he saw some lions in captivity, he couldn't control his killing urges. While being feral from the lion's presence, he battled Hawkman. But the first meteor wasn't pure; the transformation would eventually kill him. Hawkman saved him by smashing the Mithra stone and Edward reverted back to human. Hawkman theorized that the Mithra Meteor contains some radiation that transforms the one who touches it into Lion-Mane who then represents an alien race who wants to terraform this planet. Days later Dawson found another meteor rock in a museum, by touching it, he was again transformed to Lion-Mane. He didn't know that Hawkman was his friend standing next to him. Edward again sensing that a lion is in captivity, attacked civilians. Hawkman tried to stop him but failed and was knocked out. Edward wanted to be super-powered human. With this goal he sought other meteor pieces to increase his power and also to stay alive as Lion-Mane. With each meteor rock he touched his powers grew. Hawkman and Hawkgirl managed to find him again and defeat him; the Hawkman thought that he might still carry some pieces of the first meteor rock in his pockets, and smashed them with a stone, reverting Edward back to human once more.
Edward Dawson had nightmare of him turning into Lion-Mane again and killing Hawkman. Later Edward Dawson was invited to the museum where Hawkman worked, and he was considered to take Katar's place. When the museum chairmen take time to discuss Hawkman's issue, Edward Dawson was kidnapped and dragged to the basement. There he was made to touch one of the Mithra Meteor pieces, Edward tried to resist but he was overpowered by the strength of Thanagarians and he transformed into Lion-Mane. He first killed the two musclemen who forced him to touch the stone and then he turned to Coral Shilak, who orchestrated it. He didn't got far, as Hawkman and Hawkgirl heard Coral's scream and arrived shortly after that. In the fight Lion-Mane managed to grab a spear from Hawkman's hands and thrust it through him. Lion-Mane then takes his leave and starts to remold the world in his image. Lion-Mane powers were still growing; he even affected people miles away and started to transform selected few into Lion-Men. Hawkgirl tried to fight him but her efforts were useless, in her last result, she grabbed him and flew high up. The cold at that height turned Lion-Mane back to Edward Dawson. Edward was then carried away to a hospital. It has been theorized that the Mithra Metorites were sent to Earth by an alien race of lion creatures to begin an invasion, but no solid evidence has been found to support this hypothesis.

Lion-Mane possesses superhuman strength, reflexes, agility, speed, and razor-sharp claws and teeth. He is overcome with feral rage, when he sees lions in captivity or in peril. He had ability to move rocks with the meteor radiation, create vacuum fields and invisible force fields. Also a power of creation was shown when he created flora and animals of unknown origin.

Edward Dawson, an archeologist was on an expedition to find Mithra Meteorite. When he found it and sent his men to retrieve it, the stone turned them to ash. He then left the meteorite to be transported safely to a research lab in Chicago. Karen Ramis was the first scientist to examine it. During one of the tests, the meteorite started to absorb power and broke free from the containment field; Edward felt compelled to approach the stone, but pushed Karen onto it to save himself. Karen was then transformed into Lion-Mane, an avatar of lion. When Hawkman talked Karen to release the power, it sought another host. It approaches Edward Dawson, but it hesitates and then says he is unworthy. Dawson craved the power of the Mithra Meteorite and broke into Mount St. Croix lab. This time he was found worthy and he was transformed into Lion-Mane and it wanted the blood of Hawkman. He flew to Chicago and killed everyone on the plane, his killing didn't stop there. Every man he met he killed on his way to Hawkman. We also learn that the hawk and lion avatars have always been foes. The two battled for a long time, Hawkman planned on using the meteor that gave Dawson powers, to take it away again, but to no avail. Then Karen Ramis returns and touches the stone and Lion-Mane, taking half of its power; she transforms half way to lion and escapes. Lion-Mane was drained from power transfer and was easily captured.
Months later he was approached by Fadeaway Man who informed him that he has a plan set in motion and few others who hate Hawkman will be arriving to town. He got his chance to attack Hawkman, but his orders were not to kill him. Lion-Mane did his job and Fadeaway Man appeared, and poisoned Hawkman. This didn't have long term consequences however and Hawkman got away. Fadeaway Man tried again at one of the parties where Hawkman attended. This time they were able to kidnap him. Lion-Mane and the gang went for breakfast in the diner, while Thought Terror was working on Hawkman. Hawkman was rescued by Hawkgirl and Golden Eagle, but his perception was altered and saw Hawkgirl as an enemy; he beat her almost to death. Lion-Mane then set some charges around the city as did others of his group. By blowing up buildings they caught Hawkman's attention and that was part of the plan. Manhawks arrived, but they only were there to prevent Hawkman from escaping. The gang then took turn to beat Hawkman; Lion-Mane got over zealous and tossed Hawkman into a burning building. Hawkman recovered and tried to escape, but the Manhawks attacked him, Fadeaway Man let them do their job and left with his gang. Lion-Mane got his payment and went to vacation to Africa, where he was loved and treated as king. His happiness was a brief one, Hawkman had returned from the dead and attacked him with an axe; asking the whereabouts of Fadeaway Man. Surviving his injuries he was imprisoned.
Lion-Mane was released from prison when Deathstroke's team tried to kill Bombshell there and released prisoners to distract Cyborg and Miss Martian. Lion-Mane took the opportunity and escaped.
He once worked with Prometheus when he planned to destroy several cities, Lion-Man planted a machine in St. Rock. There he fought with Hawkman and Hawkgirl.
During the Brightest Day event, Hawkman and Hawkwoman encounter a tribe of Lion-Mane like beings in the border world Hawkworld. They are fittingly called the Lionmane Pride, but any connection between the two is as of yet unknown. The theory of Mithra Meteorites being sent by lion creatures to Earth may have more support, with the Winged Wonders transported to Hawkworld.

He rules over the Marabunta diamond mines in Africa. When Batwing came to shut the mine down, Lion-Mane was confident that his three wives could take care of him, but when they were defeated, he attacked Batwing himself. Despite Batwing's technological edge, Lion-Mane's physical might was too much for the hero to handle. Batwing gave up a good fight, landing plenty of hits in the process, but ultimately Lion-Mane had Batwing at his mercy. It was then that Batwing called in his vehicle and it smashed Lion-Mane into a wall, knocking him out. The villain was then being transported via plane by authorities but the Marabunta attacked and successfully took over the plane. They told Lion-Mane they were going to kill him, but the locked up villain then bit off the gunman's arm. Marabunta opened fire and shot him several times, but he was fine. Lion-Mane swiftly tore apart his enemies and then jumped from the plane swearing to kill Batwing.
