Superman's History
Original multiverse
Early life
Like the majority of Kal's doppelgangers, he was raised as Clark Kent and grew up to become the hero known as Superman. As Superman, Clark had several "go-arounds" with Lex Luthor and once went "nuts and fought himself". He also at some point married Lois Lane and had a son, Jason. After a reject from Gotham believing the Daily Planet wasn't covering him enough, he played a "practical joke" and gassed the building, killing nearly everyone inside, including Lois and countless friends and coworkers of Clark's. Despite this great tragedy, Clark held on to hope, as he believed it would shine through the darkness, a belief which he symbolized by embracing a black and red crest.
Anti-Monitor Crisis
After the Monitor found a Kryptonian who felt great tragedy to be the "Paragon of Truth", Clark was visited by Clark Kent and Lois Lane of Earth-38, and Iris West-Allen, who explained the situation to him; the Paragons were needed to save the multiverse, but Lex Luthor was out to kill all of its Supermen. Luthor promptly arrived and used the Book of Destiny to make Earth-96 Clark attack Earth-38 Clark. They briefly fought, but after Lois knocked Lex out, they were able to get through to Earth-96 Clark and stop him. They returned to their base of operations, the Waverider, where Clark met his Earth-38 counterpart's son, as well as Clark's Earth-1 doppelgänger, Ray Palmer. They attempted to use a machine to locate the other Paragons, but only found one; Kate Kane, who was in the room with them.
During the Anti-Monitor Crisis, Clark joined the Council of Supermen.
Clark then teamed up with J'onn J'onzz to defend the remaining quantum towers, but they were ultimately unsuccessful as every Earth was lost to the antimatter wave. They were forced to return to the Waverider in Earth-1, the last universe remaining.
Once back on the Waverider, the heroes were greeted by Harbinger, who had returned after mysteriously disappearing. Pariah also appeared and the heroes realized that Harbinger's return was a trap by the Anti-Monitor, who proceeded to incapacitate the heroes, kill Mar Novu, and destroy Earth-1. Realizing what the Monitor wanted him to do, Pariah managed to send the 7 Paragons to the Vanishing Point where the Anti-Monitor couldn't reach them as the Waverider was destroyed and the remaining heroes killed by the antimatter wave. At the Vanishing Point, the Paragons witnessed as Clark slumped over, disappeared, and was replaced by Lex Luthor, who had used the Book of Destiny to make himself the Paragon of Truth, switching places with Clark and succeeding in his mission of killing all Supermen.
New multiverse
One month later, after the end of the Crisis with the Paragons and the Spectre creating a new multiverse, including a new Earth-96, Clark was restored alongside all of his fellow denizens. It appears that no great tragedy occurred to him in the new timeline, since Clark was seen wearing his classic red and yellow crest on his suit while flying around the Earth as Superman.
