The weak red flash in the emerald monster's eyes was a glimmer of hope amidst the stifling darkness, a quivering reminder of the resilient core of Conner's true self fighting against the disorderly corruption. The temporary disruption of Umbra's complete domination had established a vital window of opportunity, a short break in the cacophony of dissonance which had swept over them.
Umbra, her face twisted into a grimace of angry incredulity, attacked the emerald creature, her dark hands extended to re-form the severed bond. "No! You belong to me now! You are the chaos embodied!"
But the monster pulled back from her touch, a low rumble of growling deep within its chest, this time flavored with a spark of something that resembled. aversion? The red light in its eyes surged for an instant, trying to hold back the fading green glow.
"Conner!" Aqualad cried again, his voice charged with renewed desperation. "Fight it! Think about your friends!"
Wally, noticing the change, joined in with his appeal. "Yeah, Super-bro! Don't forget M'Gann's cookies! You snuck and enjoyed them!"
Robin, always the realist, saw his chance to move. Unleashing a specialized net infused with energy-dampening fibers, he fired it at the momentarily stunned beast, hoping to cage its vast power. The net, blazing with blue energy, wrapped around the emerald beast, its fibers closing around its scaly form.
The creature howled in rage, the green glow bursting afresh as it contorted against the energy trap. The wild energy aflame around it surged aggressively, trying to scorch through the bounds.
Zatanna, sensing her opportunity, released another directed burst of counter-magic, this one aimed at the lingering wild energy clung to Conner. "NoisivreP dna ytiruces," she muttered, her spell meant to cleanse the lingering corruption and bolster Conner's own inner strength.
The wave of pristine arcane energy engulfed the straining creature, making it convulse wildly. The green light pulsed and waxed dim, and the red light within its eyes grew stronger, contending for dominance.
Michael, his mind unswerving, sustained his mental connection with Conner, reaffirming the positive anchors of his memory and identity – Superman's acceptance, his emerging friendships with the team, the moments of shared understanding between them. He wove mental pictures of belonging, of purpose freely chosen, a dramatic counterpoint to the imposed narrative of his creation and the wilderness servitude Umbra provided.
The fight for Conner's own soul raged in the bars of the energy net and the crumbling warehouse. The green beast flailed wildly, caught between the primal desires of the wild change and the coming surges of its old self. The red light in its eyes danced wildly, a flickering spark struggling against a hurricane of green madness.
Umbra, infuriated by the creature's obstinacy and the heroes' desperate attempts, released a flood of raw chaotic energy, focusing on the energy web and the captive heroes. The emerald bolts ripped through the rest of the rubble, compelling Aqualad to fortify his watery globe and Zatanna to bolster her magical barrier.
"Never take him away from me!" Umbra screamed, her voice passionate with a fury of possession. "He is the key! The birth of genuine chaos!"
As the mad energy crashed into the energy web, its strands started to buckle and strain. The green beast howled in agony and rage, the war within itself visible as it tore asunder. The red glow in its eyes began to flash one final time, a last cry for acknowledgment, before it was overcome by a final, spastic jerk of emerald madness.
With a cacophonous scream, the green monster tore loose from the broken fragments of the energy net, its shape now emitting an even stronger and more wild chaotic energy. The scarlet flash was no longer visible, having been smothered by the sheer taint. The thread of hope had been cut.
But at that last instant of inner conflict, something changed inside the creature. The unthinking, raw fury seemed to take shape, to develop a horrific intent. Its green eyes, now blazing with an icy, evil intelligence, fixed on Umbra. A deep, rasping growl sounded in its chest, no longer one of pain or bewilderment, but of raw, unalloyed mastery.
The emerald and shadow pact had broken, not through the efforts of the heroes, but through the internal instability of chaos itself. The increased power that Umbra had tried to dominate had served its own master, and the unwitting ally had become an even greater, now unstable, menace. The cost of separation was not Conner's return, but the release of a more intelligent and significantly more dangerous chaotic being.
