Fan Casting Thomas Wayne, Jr. in Batman: The Dark Knight Begins Again

At the beginning the film, we see a flashback scene between Bruce and his deceased brother, Thomas Wayne, Jr., better known as Owlman. Later on, after finally escaping the Phantom Zone, Bruce learns that, during the fourth year of The Injustice Wars, Owlman had fought The Batman Who Laughs in a quest to avenge Bruce, who was believed to have been dead at the time. However, this mission cost Thomas his life, as he was wounded by Jokerized soldiers of The Regime, before finally getting killed by The Darkest Knight, who drove a Kryptonite spear through Thomas's Nite Owl armor and into his chest. Later, Bruce visits the grave of his brother, apologizing for not being there to save him.
