To understand Darkseid, lord of Apokolips and dark god of the Fourth World pantheon, one must first understand Uxas, his prior incarnation. The son of Yuga Khan, original ruler of Apokolips, and his consort Queen Heggra, Prince Uxas plotted from his youth to conquer first his homeworld and then the universe by any means necessary. He was the opposite of his older brother Drax, who sought peace with New Genesis, and—recognizing that he was an obstacle—he slew his brother when he attempted to tap into the Omega Force from Apokolips’ Infinity Pit. Taking his brother’s birthright for himself, Uxas was transformed by the energies of the pit and, pleased with his new appearance, changed his name to Darkseid, a name from Apokoliptic lore.
Wow I was so wrong....
Darkseid at one point claimed that no living being had ever survived the full force of the Omega Effect, but extremely powerful beings, such as Doomsday and Superman, have survived them, and they have been shown to be ineffective against the bracelets of Wonder Woman.
Man I was wrong there too.....
Unknown to Superman, Doomsday had faced and beaten Darkseid himself in single combat (even surviving Darkseid's fabled Omega
Beams) and was laying waste to Apokolips. He was able to break Superman's left arm with limited effort, as well as outmatch and beat Darkseid unconscious in physical combat.
I guess Darkseid is a great fighter, seeing how it took a mindless killing machine to beat him.
With centuries of experience, Thor is a superb hand-to-hand combatant and a weapons master excelling in the use of the war hammer, sword and mace.
Damn, I'm wrong again, Thor is not a trained warrior like all Norse Gods/Vikings. Man this is not my day.
