A young Clark Kent works as an intern at the Daily Planet in Metropolis while secretly using his developing superhuman powers to fight crime and save lives. He grapples with his identity, feeling out of place due to his extraterrestrial origin from the now-destroyed planet Krypton. When his act of saving a space mission puts him in the public eye, he becomes the subject of media fascination. Clark encounters his first real test when a menacing alien bounty hunter named Lobo arrives on Earth with the intention of capturing him, having discovered that he is the last survivor of Krypton.

As the battle between Clark and Lobo unfolds, the chaos inadvertently leads to the release of a dangerous creature known as Parasite. As Parasite absorbs the energy and powers of every being it touches, it becomes a growing threat. Struggling with his self-imposed responsibility to protect humanity, Clark must come to terms with what it means to be a hero and how to use his abilities for the greater good. The arrival of other notable figures with their own agendas and abilities further complicates Clark's journey as he navigates his transformation from a man of tomorrow into a legend of today.
