It looks like Batman has a son that's more deadly than Damian Wayne could have ever dreamed of being. Batman, Jr., Bruce Wayne's child from Earth-154, is so dangerous, he once threatened reality itself simply by existing.

DC fans know that one of the most skilled and lethal members of the Bat-Family is Bruce's son, Damian. The boy is also the child of Talia al Ghul and was raised by the League of Assassins from birth, turning him into a veritable killing machine by the time he could walk. Though he left his mother and her ways behind, Damian Wayne struggled with breaking away from his conditioning, finding it hard to operate without killing. However, he did put a stop to his deadly ways, though he still remains one of the team's more brutal fighters. He may not kill anymore, but Damian certainly knows how to make his enemies hurt.

But there's another progeny of the Dark Knight, and he was far more threatening than Damian ever was. Bruce Wayne, Jr., aka Batman, Jr., is introduced in the story "The Sons of Batman and Superman!" by Edmond Hamilton and Curt Swan in World's Finest #154. Bruce, Jr. is the son of the Kathy Kane Batwoman and Bruce, and is the best friend of Kal-El, Jr. The two scions of DC’s greatest heroes decide to form their own team, the Super-Sons. However, in World Finest #263’s “Final Secret of the Super-Sons” by Dennis O’Neil and Rich Buckler, the next generation Batman and Superman discover their world is actually a computer simulation and escape into the real world. Unfortunately, their bodies contain radiation that causes the world to begin destablizing, forcing their 'fathers' to destroy them in order to save the planet.

Batman, Jr. Is The Most Dangerous Bat-Family Member

Sure, there are other members of the Bat-Family that could pose danger to others like the Red Hood or Cassandra Cain. But no one in relation to Bruce has ever been able to threaten the entire world like Batman’s computer generated son. Even Damian, who is currently the mind-controlled puppet of the Devil Nezha in Batman vs. Robin hasn’t shown an ability to put the planet in jeopardy. But Batman, Jr.’s mere existence could have done something no Bat-Family member is capable of: Destroying the DC Universe.

Granted, Bruce Wayne, Jr. isn’t real in the way that Damian Wayne or Jason Todd are. But Batman did help create the simulation that brought Batman, Jr. to life, making him the Dark Knight’s child in a way. While it’s unfair that Bruce, Jr. was condemned to merely a simulated life, his presence on the real Earth put everyone and everything in danger. Sure, some of Bruce’s children have legit body counts, but none of them have ever been a threat to reality before. Knowing that he could have potentially ended the DC Universe for good makes Batman’s forgotten son one of the deadliest heroes to ever be created.
