The night hung heavy over Gotham City, casting shadows that danced across the rooftops where the Batbrothers stood, united against the looming threat. "We need to shut down that portal, now!" Dick's voice cut through the darkness, urgency dripping from every word as he surveyed the scene before them. Damian nodded in agreement, his jaw set with determination, while Tim's fingers flew across his keyboard, desperately trying to override the villain's code.

But it was too late. With a deafening hum, the portal crackled to life, its swirling vortex threatening to tear reality apart at the seams. Before they could react, they were pulled into its chaotic embrace, tumbling through time and space until they landed with a jarring thud in a place that felt both familiar and strange.

Tim's eyes widened as he took in their surroundings, noting the scattered comic books that littered the room. His fingers brushed over the pages of one titled "Robins," his brow furrowing in confusion as he realized it was completely blank. "Guys, something's not right here," he murmured, his voice tinged with unease.

Before they could ponder their bizarre predicament any further, the sound of footsteps drew their attention. With a collective intake of breath, they turned to face the newcomer, their muscles tensing as the home owner entered the room and spotted the four vigilantes just huddled up around their living room.

As the tension in the room thickened, it was Jason who broke the silence with a forced, sarcastic greeting. "Well, isn't this just peachy," he drawled, his tone dripping with sarcasm as he eyed the homeowner with a mixture of suspicion and defiance. "Seems like we've taken a wrong turn at Albuquerque and ended up crashing your party, pal—"

Before Damian could stop himself, he swung a swift blow to the back of Jason's head, cutting off his snarky remark with a satisfying thud. "Enough," Damian growled, his eyes flashing with irritation.
