The train roared through the dark expanse of Gotham, a metallic beast carrying chaos on its back. Kara adjusted the edge of her mask and tightened her grip on the long blade in her hand. She stood firm, her shadow illuminated by the dim, flickering lights of the train car.
Ra's al Ghul sneered, his cold eyes scanning both Kara and Bruce Wayne, who was still catching his breath after being thrown to the ground. Despite his usual composure, Bruce's exhaustion was apparent, and the weight of Gotham's fate bore down heavily on his shoulders. Ra's let out a sharp laugh, dismissing their attempts to stop him.
"Two mere mortals wearing masks," he scoffed, straightening his suit with the air of a man who thought himself untouchable. "You cannot stop me, nor this train. Gotham's destiny is already sealed."
Bruce started to rise, his hand instinctively reaching for his utility belt, but Kara's sharp tone cut through the tense air.
"He can't stop you, maybe. But that doesn't mean I can't." Her voice was calm, laced with a quiet intensity. She unsheathed the blade strapped to her back, the silver edge gleaming menacingly in the dim light. With a fluid motion, she dispatched four of Ra's subordinates who had been beaten down earlier but were beginning to stir. Their bodies collapsed with a finality that sent a shiver down Bruce's spine.
Ra's flinched at the brutal efficiency. Unlike Bruce, who fought to incapacitate, Kara didn't hesitate to kill. Her methods were ruthless and unrelenting, the sharp crack of her blade a reminder of the stakes they were playing for.
Bruce shielded his eyes for a moment and sighed, finally catching her gaze.
"Was that necessary?" he asked, his voice steady but laced with disapproval.
Kara tilted her head slightly, her expression unreadable beneath the mask. "Do you want to risk the lives of millions in Gotham because of your moral hang-ups?" she shot back. "You know the stakes, Bruce. Sometimes, the only way forward is through blood."
Ra's watched the exchange with a bemused expression before his amusement shifted into annoyance. "You think this... child can stop me?" he growled, his tone dripping with condescension.
Kara's lips twitched in a faint smirk beneath her mask. She stepped forward, her movements fluid and measured, her presence radiating an unsettling calm. "Let's find out, shall we?" she said coldly.
Without warning, Kara struck. Her blade slashed through the air, aiming directly for Ra's chest. To his credit, Ra's moved with lightning-fast reflexes, narrowly evading her strike and pressing himself against the steel wall of the train. The sharp edge of her blade sliced through the space where he had stood moments ago.
Ra's scowled, his confidence shaken but not broken. "You lack honor, attacking without warning," he spat, but Kara was already closing the distance again.
"Honor?" she sneered, her voice sharp as her blade. "Don't preach honor to me while threatening to kill millions."
Ra's barely managed to sidestep her knee as it slammed into the wall, the force of the impact warping the steel. He glanced at the dent, his eyes widening in disbelief. This woman wasn't just skilled—she was strong. Too strong.
Bruce, still catching his breath, winced as he recalled the time Kara had accidentally knocked the wind out of him during training. He'd underestimated her once, but never again.
Kara didn't give Ra's a moment to recover. Her blade whirled through the air as she closed the distance between them, her strikes precise and unrelenting. Each swing carried the weight of her determination, her desire to end this once and for all.
"You're quick, I'll give you that," Kara said, her tone almost mocking. "But you're no better than a rat, scurrying around and hiding."
Ra's eyes darted around the train car, searching for an escape route. He knew he couldn't outmatch her in brute strength, and her unorthodox methods made her unpredictable. He retreated further, his back now pressed against the console of the train.
Kara approached slowly, her blade gleaming with the promise of finality. "Life is just a cycle, Ra's," she said, her voice low and deliberate. "And your part in this cycle ends here."
Ra's growled and shifted into a defensive stance, his hands raised to counter her final attack. But Kara moved faster than he anticipated. She grabbed his ankle with unnatural speed, yanking him backward before slamming him against the console. The impact echoed through the train car, and Ra's crumpled to the ground, blood staining his once-pristine suit.
Kara stood over him, her blade poised for the final strike, but her attention flicked momentarily to Bruce, who had finally reached the microwave emitter. He worked quickly to disarm it, his focus unyielding despite the chaos around him.
Ra's, seizing the brief distraction, attempted to lunge for an emergency exit, but Kara was faster. She caught him mid-leap, her grip unrelenting as she slammed him back down. "Did I say you could leave?" she growled, her voice a deadly whisper.
With one final, powerful swing, Kara ended it. The train car fell silent, save for the faint hum of the emitter winding down as Bruce successfully disabled it. He straightened, his gaze meeting Kara's.
"Was all that necessary?" he asked again, his tone softer this time.
Kara sheathed her blade and turned to him, her expression unreadable. "Ask me that again if we ever make it out of this alive," she replied coolly, stepping past him to inspect the now-quiet console.
The train screeched to a halt moments later, the city lights of Gotham visible through the shattered windows. The battle was over, but the war for Gotham's soul was far from finished.
