The Titans Tower common room erupted into a whirlwind of green and shadow as Eadric, the corrupted knight, stepped through the rift—his towering frame dwarfed the fallen Christmas tree, black-green armor pulsing like a festering wound, dagger gleaming with a sickly light. Kai stumbled back, heart hammering, the morpher's cracked crystal flaring erratically on his wrist—its hum a fractured scream: "Entity breach—sync collapsing!" Raven's arms steadied him, her glow flaring as she shoved him behind her, shadows coiling protectively. The air thickened with ozone and dread, the festive lights flickering out, plunging the room into a dim, chaotic glow.
"Vessel," Eadric rasped, voice a guttural distortion of Kaelric's—cold, commanding, laced with betrayal's echo. "The Grid ends with you." He lunged, dagger slashing—a jagged arc of black-green energy that tore through the air, splintering the floor where Kai had stood. Raven's shield snapped up, dark tendrils clashing with the blade—cracks spiderwebbed her barrier, and she grunted, blood trickling from her nose as she held it.
"Titans, now!" Nightwing barked, vaulting over a couch, escrima sticks sparking blue. He struck Eadric's flank, sticks cracking against armor—sparks flew, but the knight barely flinched, backhanding Nightwing into a wall with a thud that shook ornaments loose. Donna charged, limping but fierce, staff swinging—she smashed Eadric's helm, widening its cracks, but he roared, slashing her brace—metal snapped, and she fell, clutching her ankle with a curse.
Gar shifted to gorilla form, roaring as he tackled Eadric—claws raked armor, black ichor oozing, but the knight seized his arm, hurling him into the tree stump—twigs snapped, Gar crashed hard, shifting back with a groan, green blood smearing his shirt. Wonder Woman leapt in, lasso flaring gold—she snared Eadric's dagger arm, yanking with Amazon strength, pulling him off-balance. "Stand down!" she commanded, sword slashing his chest—ichor sprayed, but he twisted free, slashing back, forcing her to block with her shield.
Green Lantern John Stewart soared up, ring blazing—emerald chains snapped around Eadric's legs, binding him. "Hold him!" John shouted, sweat beading as the knight strained, dagger hacking—chains cracked, dark energy seeping, and John grunted, ring flickering. "He's too strong!"
Kai staggered up, pain lancing his side—the morpher pulsed, "Tiger shift viable—control critical!" Green light surged, armor reshaping—claws lengthened, stripes etched, a feral roar tearing from his throat. He launched at Eadric, claws slashing—metal screeched, ichor poured as he gouged the knight's shoulder, but Eadric's dagger swung, biting his chest—armor held, barely, blood welling as he skidded back, snarling.
"Kai, no!" Raven yelled, blasting shadows—tendrils snared Eadric's arm, slowing him, but he broke free, slashing her shield—she stumbled, gasping, her glow dimming. Kai's tiger form surged—wild, untamed—claws raked Eadric's helm, splitting it further—Kaelric's face glared back, hollow-eyed, a snarl twisting his features. "You're me!" Kai roared, tackling him—claws tore chestplate, ichor splashed, but Eadric seized his throat, lifting him, slamming him into the floor—concrete cracked, pain blinded, and the armor flickered off.
"Not you," Eadric growled, dagger raised. "The Grid's failure—mine to reclaim." Kai grabbed the blade bare-handed—energy burned, blood slicked his palms, but he twisted, wrenching it aside, kicking Eadric's knee—the knight staggered, roaring.
Nightwing rolled up, sticks sparking—"Raven, rift!"—and she nodded, hands trembling, weaving a shadow dome around the rift—cracks spread, her knees buckled, but it shrank. Donna crawled to Gar, propping him—"We're losing ground!"—while John's chains snapped, Eadric breaking free, charging Kai.
The morpher screeched, "Sync overload—revert or merge!" Kai clutched it, blood dripping—green light erupted, blinding, and the Tower dissolved. He stood in the Grid's void—green web pulsing, endless—Kaelric facing him, armor dented but alive, sword raised. Eadric loomed beside him—green-armored, dagger black-green, eyes hollow. "You let them take it," Eadric spat, voice a bitter echo. "The shard—our oath—wasted on you."
"I didn't—" Kai started, but Kaelric cut in, voice hard: "He betrayed us—turned for the king's greed. The Grid warped him, as it warps all who break it." The void trembled, shadows coiling—Eadric lunged, dagger slashing—Kaelric parried, sparks flying, but Eadric's strength grew, green light fracturing.
"You're weak," Eadric hissed, shoving Kaelric back—Kai grabbed his arm, pulling, but Eadric turned, dagger slashing his chest—phantom pain seared, and the void cracked, green bleeding out. "I'll take it—end this!"
Kai snapped back, gasping, Tower floor slamming into him—Eadric's dagger descended, real now, and he rolled, concrete splintering. Raven dove, shielding him—shadows clashed with the blade, cracking, and she screamed, falling beside him, blood streaking her face. "Kai—run!" she rasped, hands glowing weak.
"No!" Kai roared, staggering up—the morpher pulsed, "Entity sentient—Grid core exposed!"—and he lunged, bare fists pounding Eadric's helm—blood smeared, knuckles split, but it staggered, ichor dripping. Diana charged, lasso snaring Eadric's legs—she yanked, slamming him down, sword slashing his arm—ichor poured, but he blasted free, dark energy knocking her into John, both crashing hard.
Nightwing flipped to Raven, dragging her back—"Close it, now!"—and she nodded, hands shaking, dome tightening—rift shrank, Eadric roaring as green light dimmed. Gar tackled him, bear claws raking—ichor splashed, but Eadric flung him into Donna, both crumpling. John's ring flared, a construct cage trapping Eadric—he hacked, chains cracking, and John fell, ring dim.
Kai's morpher buzzed—another shard broke, pain lancing his arm, blood pooling. "No more!" he roared, tiger form surging—claws slashed wild, tearing Eadric's chest—ichor erupted, the knight howling, but he seized Kai, slamming him into the wall—plaster shattered, pain blinded, and the armor vanished, leaving him raw, gasping.
Eadric loomed, dagger raised—"Yield!"—but Kai grabbed the fallen shard, its glow searing his hand. He stabbed it into Eadric's chest—green light exploded, ichor pouring, and the knight dissolved, mist swirling, rift sucking it back. Raven's dome collapsed—she fell, unconscious, rift snapping shut, silence ringing.
Kai slumped, blood soaking the floor—Nightwing caught him, voice sharp: "Stay with me!" Diana staggered up, lasso coiled, John's ring reigniting—Donna dragged Gar, both battered. Dr. Carter peeked from the hall, tablet clutched—"It's gone… for now."
The morpher pulsed, cracked wide, voice a whisper: "Core exposed—sentience confirmed. Host link severed." Kai's vision swam—green light flared, and he saw it: the Grid's heart, a pulsing orb in the void, cracked, bleeding shadows. Eadric's voice echoed, faint: I'm free… but it's not.
He jolted, gasping—"It's alive!"—and Nightwing's grip tightened, Raven stirring beside him, blood-streaked but breathing. "What's alive?" Nightwing demanded, but Kai's head lolled—green web pulsed, and a new figure flickered—green-armored, helm whole, eyes calm—Kaelric, pristine, stepping forward.
"The Grid," Kai rasped, "it's awake—and it's mad." Darkness crept in, the morpher falling silent, and he slipped under, Kaelric's gaze burning into his soul.
