Damian took Bruce's place almost three years ago as the wearer of the Bat-Man costume, making him the new Batman and one of those responsible for maintaining the Justice League together with Jonathan, his best friend and current Superman. They have always worked well as a team since childhood, even with occasional disagreements and hidden secrets.

No one but Alfred, Bruce and a select few from the Wayne company knew the secret Damian had been keeping since his gender manifestation. Damian Wayne, the current Batman, is an Omega.

He spent years hiding his gender from anyone he didn't trust, posing as an beta with drugs developed at Wayne Industries that altered the scent of his pheromones, making him smell like an beta and repressing his heats. And this tactic worked for years until his body adapted to the medicine and a new formula was needed to continue his charade. And this is how he has lived for almost 10 years, currently 21 years old and hiding his gender until the fateful day that the medicines stopped taking effect once again, leaving him in the situation that the narrative goes through.
