Who is he? He is Luthor's experiment, Luthor's 'son', and Luthor's toy. He has abilities like Superman.
He obeyed Luthor. He never knew his true identity. He only knew that he had to obey Luthor until he met Superman.
The protagonist is a clone of Superman, but due to Luthor's interference, he is exactly the same as Superman except for his eyes. And unlike Superman, he has no compassion. He can be extremely gentle to anyone, but he is never really gentle. Just disguise.
The protagonist's abilities are not as good as Superman's, but he has no mercy or emotions. He can use anyone as long as he can complete the task. He never protects others. He doesn't mind using himself as long as he can succeed. He never refuses to kill.
Superman can be substituted for Heng Chao, Batman can be substituted for Batman [just ask because I love him], and the background is that Batman has just debuted a few years ago, Superman has been debuted for a long time, the Justice League has not been established, but there are all the people who should be there, and the Flash Green Lantern has just debuted [group members substitute as members of the Justice League in Dawn of Justice]. Luthor substitutes the haired Luthor of Dawn of Justice to thank me for loving him.
Concept: The life of a 'pseudo' superman
