Fan Casting Thomas Wayne, Jr. in Injustice: Avenged

After getting back to Earth-1610 at the end of Injustice: Red Son, Clark Kent noticed that Thomas Wayne, Jr., who aided him in creating his rebellion against The Regime, was absent from the group of heroes that survived the apocalypse caused by The Batman Who Laughs. He asks Selina Kyle about his absence multiple times, seeing that she is sad every time Owlman is mentioned, before she finally tells him that, while Superman was stuck in a Flashpoint timeline of Earth-13, Thomas Wayne, Jr. had died fighting The Batman Who Laughs. Later on, Kal-El visits Thomas's grave in Gotham City, where he is buried right next to his parents and nephew.
