Summary: When Percy finally conquers Gaea with the absorbed powers of the Seven, half of the world is destroyed and his beloved Annabeth is dead. He makes a daring plan to go back in time and destroy the Titans and Gaea before they wake with his newfound powers. Will he succeed? !Powerful Percy

A/N: Feel free to review, but please remember that I am human, and that I have feelings too. :)

Percy Jackson wiped the grime from his eyes as he plunged Riptide down in one fluid motion. An earth-shattering scream filled the air as the Celestial Bronze ripped through the diamond without trouble and pierced the Heart of Gaea.

The Earth rumbled in pain as the once-powerful Primordial goddess died in slow agony, screaming and thrashing and bleeding.

Percy spat.

His once-playful eyes now only contained a somber soul. He harbored no qualms about killing one of the most Primordial of goddesses— h*ll, he harbored no qualms about killing anyone. There was nothing left. Nothing left to live for anymore.

Camp Half-Blood had been utterly decimated, now a pile of stone and tarnished rock and all sorts of rubble. The once-mighty cabins were now pale shadows of themselves, broken and cracked beyond repair.

Camp Jupiter had not fared nearly as well; without a protective barrier surrounding their camp, everything had been crushed under the might of the San Andreas fault. Percy could vividly remember circling the camp on pegasus and watching helplessly as the entire camp folded in on itself, crushing everything within— including Frank, Jason, and Reyna, and the rest of the seven.

Flashback

He had jumped down from his aerial vantage point immediately, desperately pawing at the rubble. From under a particularly large rock, the Praetors Jason and Frank, Annabeth, Leo, Piper, and Hazel stared wide-eyed at him, all dead. They never really did get a chance to finish their senate meeting.

Tears fell from his eyes and he pounded the ground in grief. The water around him roared up in huge waves, smashing everything in its path.

And then the waves receded and Percy fell into silent tears.

"Percy…" the broken demigod glanced down to see the group grinning weakly at him, bleeding from a dozen places. But still alive.

"You guys are alive?" he gasped. Instantly, he moved to push away the rubble, but Frank's muscled arm stopped him.

"Not.. much time left…" he gasped. "I, Frank Zhang, surrender my powers to Perseus Jackson in the hope that he will use them to defeat the Primordial Goddess Gaea." As soon as he finished his sentence, he splayed over, coughing blood. Percy stumbled back as Frank's life force literally merged with his- and suddenly, the powers of a thousand animals entered him all at once.

The force nearly knocked him to his knees.

He was dimly aware of his arms becoming more muscular, his hair tinting dark, and his stomach gaining newfound abs. His eyes turned from a sparkling green to a chocolate brown- the color of Frank's eyes.

He felt the world turning dark…

"Don't you lose consciousness on me!" Jason gasped. "I, Jason Grace, surrender my powers to Perseus Jackson in the hope that he will use them to defeat the Primordial Goddess Gaea."

Thunder rumbled across the sky, and Percy felt the air around him responding to his will.

Percy stumbled. "Guys…"

And then his voice choked up and filled with bile. He coughed twice.

His body transformed once more. His cheekbones lifted up higher and his hair turned from a thick black to blonde. His legs increased in muscle and his hand felt far more comfortable with the sword, having inherited both Greek and Roman fighting styles. And then Jason's eyes glazed over, his gaze slackened, and his weak hand fell to the floor.

"Percy…" Piper gasped. He'd been sure the daughter of Aphrodite had been dead, but now she was grinning weakly at him. He rushed over to her.

"Please don't die on me, Piper!" he pleaded.

The girl shook her head sadly. "It's only by Reyna's power of lending strength to others that I'm still alive."

Percy glanced up to see Reyna clutching her arm shakily with a fierce, determined expression on her face. "Go!" the former praetor whispered. "Accept their gifts. Don't let our sacrifice be for nothing."

Percy nodded.

"I, Piper Mclean, surrender my powers to Perseus Jackson in the hope that he will use them to defeat the Primordial Goddess Gaea."

A force slammed into Percy's mind, and a large, invisible hand brushed him from top to bottom. Piper's high cheekbones and beautiful face were forced onto his own so that Percy became indescribably beautiful in a soft way, an elfish way.

Charmspeak came to him instantly and naturally, as if it had been there his whole life- which for Piper, of course it had.

Percy turned his attention to Annabeth, who had begun an incessant tapping on his shoulder.

"Reyna can't keep us alive for much longer." she choked. "Here…"

She grasped his neck and pushed him down to her for one last kiss.

"I, Annabeth Chase, surrender my powers to Perseus Jackson in the hope that he will use them to defeat the Primordial Goddess Gaea."

Percy gasped as a thousand images flashed through his mind. He felt his intellectual capacity literally expand- and a thousand new possibilities entered his mind. Annabeth grinned weakly. "Goodbye, Seaweed Brain."

Her eyes glazed over, and Percy howled. Tears flowed freely down his face and he punched the cement, his shoulders heaving.

"I only have strength to keep them alive for another minute." Reyna grunted. "Hurry up!"

Percy wiped away his tears and turned to face Leo, who had a crazed look on his face. For a moment, neither of them spoke. And then-

"I thought I'd die to a giant or a hellhound or something, but instead I get murdered by a rock. Talk about anticlimactic."

Percy burst out into laughter, hysterical laughter. Though whether he was laughing or crying he had no idea; the tears had begun trailing down his face again in waves. It felt as if a hole had been punched in his chest.

"I, Leo Valdez, surrender my powers to Percy Jackson in the hope that he will use them to defeat the Primordial Goddess Gaea."

A warm flame blossomed in his chest, and he felt a flame flicker on his fingers. It died away as soon as it had come.

Percy felt like collapsing right then and there. There was simply too much to take in.

"We're… not done yet…" Nico crawled up to him. He was barely alive, and one of his hands were limp. Shards of stone stuck from him in a dozen places, but he ignored the pain.

"I, Nico Di Angelo, surrender my powers to Percy Jackson in the hope that he will use them to defeat the Primordial Goddess Gaea."

Darkness enshrouded Percy, and for a moment he thought it would consume him; but then the shadows ebbed away. He shuddered as they entered his skin; it felt as if a giant sponge was pressing in on him from everywhere at once.

The feeling disappeared as the last of the shadows ebbed into nothingness.

Flashback End.

Lightning struck the place where Percy's saliva had fallen. Flame enshrouded the world and he felt himself transform. A grizzly bear stood where Percy Jackson had been, bashing away at the hard encasing of Gaea's heart with seemingly never-ending strength.

Shadow ripped away at the diamond in waves; charmspeak forced Gaea into semi consciousness.

Percy raised one hand, and he felt the forces of the universe respond to his will. Lightning, flame, shadow, and ice struck his palm and overlapped, creating a giant sphere of pure destruction.

He rammed it straight into the crevice created by Riptide- straight into the now-defenseless heart of Gaea.

The subsequent scream could be heard for miles. Earth and water erupted, and molten magma exploded from the earth in huge waves. A thousand lightning bolts struck all around the world at once, and the huge force threw Percy to his knees. He gasped as his eyes were literally sealed shut by the sheer power of the explosion.

He felt himself close to unconsciousness, and, with the last vestige of strength, willed the air around him to rocket him a thousand feet into the air, far, far away from the explosion…
