The midday sun beat down on G otham.This was Duke's time, the time when the shadows receded and the more mundane crimes flourished.

As the Signal, he patrolled the sun-drenched streets, a splash of yellow and black against the urban grey.

He preferred the quiet hum of daytime to the cacophony of the night, the hushed anxieties of the city instead of its outright terrors.

But lately, a new kind of unease had begun to creep into the daylight hours, a verdant threat that thrived under the very sun he embraced.

A series of strange occurrences had plagued G otham for the past few weeks. Parks spontaneously overgrown with alien flora, inducing strange, vivid hallucinations.

The common thread? They all happened during the day. B-atman, preoccupied with his nocturnal duties, had delegated the investigation to Duke.

He knew the whispers on the rooftops, the comparisons to Pois-on Ivy. But this felt different, wilder, less calculated. Ivy, despite her methods, possessed a certain twisted logic. This new menace felt…chaotic.

Today, Duke found himself investigating the latest incident: a local botanical garden transformed into a jungle within the span of a few hours.

The air hung heavy with a sweet, cloying scent that made Duke's head spin. He pressed a hand to his mask, the filters struggling to keep out the intoxicating aroma.

"This isn't natural," he muttered. He carefully navigated the overgrown pathways, his boots crunching on unfamiliar leaves.

He reached the center of the garden, where a massive, pulsating pod dominated the landscape.

He could feel a low hum emanating from the pod, a vibration that resonated deep within his bones. This was the source, the heart of the strange growth.

He reached out a gloved hand to examine the pod’s surface, when suddenly, the surrounding vegetation began to writhe. Vines, thick as pythons, lashed out, forcing him to backpedal.

He knew, with chilling certainty, that he was facing a new kind of enemy, one that held dominion over the very plants he relied on for oxygen.
