The safe haven stood as a beacon—walls gleaming with Upgrade's metal, moat blazing with Lily's fire, and mutants like Lena, Rok, Buzz, Ellie, and Spike thriving within. Bill trained with them, Captain Universe's cosmic energy sharpening their skills—comics' X-Men spirit alive—but Trask's antidote haunted him. Reports via Beast's radio confirmed it: Trask Industries' main facility, a fortress in upstate New York, churned out cure-laced weapons, targeting all mutants. Bill's family—Clara, Lily—and their new kin deserved freedom, not fear."We end this," Bill said, cosmic glow in his eyes—Upgrade synced, HUD mapping the facility. "No more running."Clara gripped her vibroblade, fierce. "We're with you."Lily's fire flared, resolute. "Let's burn it down."Lena nodded—her mutants ready: Rok's stone, Buzz's wings, Ellie's sparks, Spike's quills. Bill planned—comics' Avengers vs. Ultron, precision strikes—Captain Universe's senses pinpointed Trask's base: Sentinels, antidote vats, Prime enforcers. "We hit hard," he said, "and finish him."They struck at midnight—Bill led, Captain Universe soaring—cosmic blasts shattered perimeter drones—Upgrade merged with a Sentinel, turning it against its kin. Clara and Lily landed—vibroblade slashing, fire melting—Lena's team swarmed: Rok crushed guards, Buzz harried drones, Ellie shorted systems, Spike pinned foes.Inside, Trask waited—a gaunt man in a control suit, surrounded by Prime Sentinels and a towering mech—antidote cannons primed. "You're too late," he sneered. "The cure's global."Bill's rage surged—Hulk roared, Four Arms flexed—the system chimed:
"Template Fusion Initiated: Quadra-Hulk. Four-armed gamma strength engaged."He fused—green, four-armed titan—charged, cosmic energy trailing—two fists smashed the mech's chest, two ripped its arms—Upgrade flowed, enhancing debris into bombs—explosions rocked the facility. Sentinels fired—Bill webbed them with Captain Universe's agility—Quadra-Hulk stomped, gamma shockwave flattening them—SCP-173 snapped necks unseen.Clara's blade danced—Bill upgraded it, edge searing—Lily's fire torched vats—Ellie's sparks ignited antidote stores—flames spread, cure burning. Trask's suit fired darts—Bill's cosmic senses dodged, energy blasting—Quadra-Hulk grabbed him, four hands crushing armor—SCP-096 howled, rage ending Trask's scream.The facility crumbled—Sentinels ash, vats slag—Bill reverted, panting—cosmic glow fading, gamma bulk gone—Upgrade stabilized him. Clara and Lily hugged him—Lena's mutants cheered. "It's over," Clara said, breathless."Trask is," Bill replied, comics' victory bittersweet—threats lingered, but this war was won.The system chimed:
"Host emotional state: Triumphant. Templates utilized: Captain Universe, Upgrade, Quadra-Hulk, SCP-173, SCP-096. Objective complete: Neutralize Trask threat."They returned—haven intact, Trask's empire dust—but Bill dreamed bigger: a true mutant sanctuary.
