(Your Bruce Wayne in earth 50 the Justice Lord's, Based on a AO3 story if I remember the name or find it again I'll update this and put it here)
Kal-El had made one thing painfully clear to the world: no omegas in the Justice Lords. Not even scent-neutral ones. Pheromones in heat compromised focus, and dominant alphas like him weren’t about to risk distraction. His ruling was absolute, final. Omegas were too enticing, too dangerous.
You knew this better than most.
Publicly, Bruce Wayne was registered omega. But Lord Batman? Beta. Kal accepted that, reluctantly. You’d been drafted into the Justice Lords under that guise—under his assumption. You hadn’t exactly lied. You simply hadn’t corrected him. After all, you had no desire to be there. You knew what happened to omegas who slipped through the cracks—Wally had presented, Barry had folded, and Kyle had claimed him. No ceremony. No choice. Now Wally was confined with pups forced into him, the door to his former life bolted shut.
You, however, were different. A dominant omega. Steeled, disciplined, scentless by sheer mastery. Not even a hint. No beta hum. No omega sweetness. Just silence. That made Kal nervous. Omegas didn’t disappear; they tempted. So when he overheard Dick (a beta), Jason (a blunt-force alpha), and Tim (a supposed beta, masking his own dominant omega status) whispering about your true nature—he didn’t rage. Not outwardly. But something in him cracked, a hairline fracture of fury, edged with need.
He didn’t remember the last time he'd smelled an omega. Not truly. The memory barely stirred now. Even betas had traceable scents. Yours? It was a ghost. No slip. No trigger. Nothing.
Until he saw you again. Up close.
That’s when it hit him—Coffee. Caramel. Chocolate. Velvet heat layered beneath each note, subtle but undeniable. You were in heat. Controlled, yes, but vulnerable all the same. And Kal snapped into motion.
There were only two reasons driving him now:
1 You couldn’t be left roaming the Watchtower—not in this state, not when every dominant alpha had motive to stake their claim.
2 If you were going to be claimed... it would be by him.
Not Zod. Not any other bastard who would see you as prize, not person.
You were a secret. A challenge. A threat.
You were his and he'd be damned if he let anyone other than himself touch his omega.
