Jason Pulls a Bruce Wayne

On ao3. Author is Libby_The_ Survivor.

Jason Todd was many things. A former Robin, a reluctant member of the Bat Family, an uncle to Mar'i and Lian, a former crime lord, an anti-hero known as the Red Hood. What he is not, is a father. Well, at least he wasn't until the Lazarus pits spit out a baby boy who looks remarkably a lot like he does, an ancient ghost who tells him that this baby is now his son and to keep him safe. Oh! And did he forget that the baby is the future Ghost King and has some type of Eldritch powers and he finds out that he was something called a Revenant?

Of course, he decided to lay low for a bit and not tell anyone he now had a kid whilst he sets the boy up with some papers, because how was he supposed to say that the baby was birthed by pit water? And oh look, Bruce and the rest of the Batfamily want to meet the new member of their family! Perfect. This wasn't how he expected his day to go when he woke up.
