The chamber trembled violently, cracks spiderwebbing across the stone floor as ancient machinery groaned awake beneath the city. Dust and debris rained from the ceiling, choking the stale air.
Tony Stark's muscles screamed in protest as the glowing energy cuffs pulsed relentlessly, but his mind was razor-sharp. Beside him, Steve Rogers moved with quiet urgency, his shield at the ready. Natasha Romanoff's eyes scanned every shadow, alert for traps.
"We don't have much time," Steve said, voice low but firm. "Doom's playing with forces beyond technology — something primal."
A low rumble echoed through the chamber, the sound of something massive awakening. Tony's heart pounded — he could feel it in his bones.
Suddenly, the energy chains snapped.
Tony flexed his wrists, shaking off the last of the bonds. He rose, every movement fueled by the fierce determination that had made him Iron Man.
"Let's finish this," Tony said, his voice raw but steady.
They rushed toward the shattered door — only to be met by a wall of shimmering green energy. Doom's magic blocked their path, crackling with deadly power.
"Fools," Doom's voice boomed through the chamber, "you cannot escape the fate I have forged. The city, this world — they belong to me now."
Steve raised his shield, slamming it into the magical barrier, sparks flying.
Natasha's weapons glowed with intensity as she prepared to strike.
But before they could advance, the ground beneath them exploded.
From the depths rose a monstrous figure — ancient, armored in stone and metal, eyes glowing with the same eerie light that filled the chamber.
A titan awakened from the forgotten past.
Tony stared, breath caught in his throat.
Doom has unleashed the Leviathan — a creature of power beyond reckoning.
And as the beast's eyes locked on them, Tony realized the fight was no longer just for survival — it was for the very soul of the world.
