Superboy (Young Justice)
Young Justice: Rebirth Comic Prelude | Young Justice FanFiction Wiki | Fandom
In its third season, Young Justice has made a major leap forward in time, as the teens from Season 1 have become adults, and key members of the Justice League. Conner was previously portrayed, effectively, as the son Superman ignored. However, for some time after the boy's escape from the lab, Superman refused to connect with the teen, and we eventually learned it was because he didn't know whether he was ready to be a father. Conner used Lex's drugs to gain even more of Superman's powers, all so he could feel an emotional connection to Kal, showing just how much he craved that approval. His team uses the Boom Tube to teleport to a mysterious solar system, where Superman is surprisingly found fighting off Parademons while Metron looks on. Conner joins the Man of Steel, and together they fight off the attackers. As they talk afterward, Superman acknowledges Conner as his little brother.
