Batman Reboot Concepts

Chapter 2: Cass And Dami: Twins?

What if when Talia mixed her and Bruce's DNA, it didn't just result in one child, but twins?

In this world, Damian is the perfectly obedient little heir he's supposed to be. Despite his grim fate, he would go to it willingly, unable to comprehend fighting back...

...if it wasn't for Cassandra. We know that the League Of Shadows/Assassins/Whatever is sexist, so I feel like mixed with her muteness, she wouldn't be treated well. Damian cannot stand for this.

Cassandra starts off as the only person Damian cares for unconditionally, the one person he can accept weakness in and show weakness to, the one person he would stand as equals with no matter the circumstance. For her sake and her sake alone, Damian defies their Grandfather and runs away to Gotham with Cassandra.

Damian doesn't think his father will accept him, but hopes he might find Cassandra useful enough to protect. Before he hands his precious sister over to a man he's been raised to view as an enemy and goes to face death by the League (he can't return to them, he knows they'll make him kill Cassandra if he does, but at least he can go out fighting), however, he wants to gather information.

Damian and Cassandra try to survive in Gotham by themselves, but they don't understand how the wider world works. Luckily, they find refuge in the Sewer Kingdom (I'll devote a chapter to them, let's just say they aren't exactly bad for now). They learn many new skills from the children of the sewers, including a marvelous thing called sign language.

Cassandra is very happy. She can 'talk' with others for the first time in her life, she's making all sorts of new allies (maybe friends, though she's not sure how that works), and even Dami seems happier. Life is harder in some ways, but at least they don't have to hurt anyone. Things are good. Of course, the League eventually finds them, and Cassandra lets herself be captured to give Damian a chance to go for help.

Damian is not ready to face his father, but needs must. He doesn't immediately reveal himself as a Wayne, only telling Bruce that his sister has been captured by the League and he will reveal the Bat's identity if he doesn't save her. Bruce of course immediately goes to save the child, planning to deal with the adorably-angry-and-vaguely-familiar child trying to threaten him after.

Long story short, Cassandra is saved, identities are revealed, and Bruce takes in his new kids who eventually become Robin and Batgirl. Damian is still worried he will be cast out if he slips up. Cassandra knows Bruce would never do that and as well knows that her brother will realize that eventually, so she mostly just contents herself with learning ballet and eating Alfred's cookies. Life is good.

Oh, and they're part literal demon, which leads to some interesting things, especially with Scarecrow (who is consensually possessed by a demon). But that's a story for another time.
