Hi guys! This is a shortish chapter. I'm sorry!

This is kind of a TMI crossover. If you haven't read that series, then this will be more mysterious for you. If you have, then you'll know Agramon is OOC. He's modelled a bit like Kronos here.

As this is the final chapter, I feel obligated to say, thank you for the favourites, follows and reviews. Keep it up!

Disclaimer: I don't own Percy Jackson. Damn.

"Can you believe we've been at camp for seven years?" Megan asked.

"Not really. I mean, besides this Demon War, which Chiron said wasn't as bad as the Titan or Giant War, everything's been low key." Aden shrugged.

"A war isn't low key." She retorted, standing up quickly. "Hurry, I can hear them."

Everyone else in the mall where the Campers had been hiding, went still. Even the special warriors Jace, Isabelle, Alec and Clary that Chiron called in, who claimed to be experts.

The silence was deafening. Charles of the Hephaestus cabin checked the video feed. "We have about ten minutes. From our calculations, this is the final wave until the real deal comes."

"Agramon." Jace cut in.

"Whatever."

"Apollo cabin, take the stairs to the roof and take out as many as you can. Hunters, you be the front line along with the Ares campers." As senior Athena camper, Megan, along with the other senior campers were in charge.

"We'll go next. I see a nearby park. Plenty of plants for us." Alina of the Demeter cabin smirked. The Hecate cabin was in charge of the illusions that would surely throw the demons off. "They aren't the smartest." Clary had informed a while back.

As the only Poseidon camper, Aden would burst the water pipes that ran under the city.

Agramon's main goal? Kill everyone or turn them into his slaves. His eyes were on the Gods though, they would be fine servants when he ran the world.

"Five minutes." Charles shut of the video feed and everyone ran to their stations.

Aden had to admit, the warriors Chiron had hired were pretty good. Their weapons had nothing on his sword though. It had been given to him by his father himself.

Anaklusmos.

He cut down eidolon demons, ravener demons, until it all blurred into blood and death. The entire wave was demolished, with only a few casualties. As Clary had said, the demons weren't very smart. It was only a matter of time until Agramon appeared.

He just spotted Megan, eating a bit of ambrosia. The long cut that ran up her leg disappeared.

"Hey." He sat next to her.

"Hi." She offered him a bit of the food and he gratefully accepted it. He felt his scratches and the pounding headache from controlling so much water, disapear.

"I just wanted to thank you for being my best friend." He patted her shoulder and went to go check on the other campers, missing her hurt look.

"HE FRIENDZONED HER!" Aphrodite wailed.

"They'll get over it. They have years more." Hades sighed from his throne. All the gods were parked in his palace in the Underworld, seeing as the fight took place so close to Olympus. And because there was really only one enemy, there was nothing they could do without interfering.

Aden spotted the warriors drawing on themselves. Their cuts vanished. They told them that the campers wouldn't see exactly what they were doing, because they glamoured themselves. "Kind of like your Mist." Isabelle had said.

"This is serious you know." The one named Clary walked up to him.

"I know." Aden responded.

"Is there anything or anyone you'd die for?" She asked randomly.

"Um, well, everyone here I guess." He was confused.

"Anyone in particular?" Aden obliviously missed her eyes darting to Megan.

"No. Now if you'd excuse me," he waved and walked off.

"Boys." Clary threw her arms up in defeat and went to stand next to her friends.

"Everyone!" Megan called. It was an undecided fact that she was the leader. She was just so leaderly. Much like a girl named Annabeth, Chiron had said. Aden knew that the blond girl from decades ago was the one person Megan looked up to. He also knew that in times of stress and total helplessness, she would ask herself, "What would Annabeth do?" He didn't see what was so great about Annabeth. Now Percy Jackson, that was a guy to look up to.

"Agramon was last seen a couple blocks from here. Are we ready?"

"Yes!" They all chorused and advanced toward where the Greater Demon was; near the Empire State building.

"it's been years since Olympus was there." Aden remembered Chiron saying.

"Ah. The half-bloods." Agramon was there, and disgusting as ever.

"And oh look, the Nephilim!" He waved in an annoying fashion. "Hello!"

"Oh screw you." Jace snarled, and charged.

Though their main enemy was demons, the warriors couldn't kill Agramon by themselves. The demi gods followed suite and soon were surrounded by more demons. The cabins split without spoken word. Most of them fought the Greater Demon, while the rest fended off the other creatures from hell.

-INSERT A BIG BATTLE-

Finally, it was just Agramon. The demons had returned to whatever dimension they were from. The bodies of demi gods however, didn't return anywhere, so all around the surviving campers, was the bodies of their friends.

"You might have won." Agramon snarled. "But I must take one more." Sludgy, black blood pooled around him and Megan knew without a doubt, one perfectly placed blow would kill him. She might have dismissed his words, except he was looking right at her.

"You." He smirked and swung his tail at her.

She ducked fast and heard the whistle as the barbed and poisonous tail missed the top of her head by inches.

"The underbelly!" She yelled. A dozen people darted towards the mentioned place, but the tail would come flying and almost, if not dead on, hit them.

Without even calculation, she knew the tail would have to go. It was too thick to chop off, so maybe...

Quick as a wink, she grabbed the tail as it nearly hit Aden. Hanging on for dear life, she noticed with satisfaction that Agramon was so focused on swinging her off, he left his underbelly wide open. More than a couple swords, arrows and seraph blades pierced it and with a howl of agony, Agramon collapsed.

Megan quickly rolled off, but their celebration was short lived. She realized her body was burning. Barbed and poisonous. Her entire body was coated with poison and her armour was already melting.

"No..." The warriors had already gone, probably back to their Institute. Aden and an Apollo camper kneeled by Megan.

"Oh my gods Meg." Aden stared in horror as her face was contorted in pain, her legs was already being eaten away by the poison. It was all really grotesque, but he couldn't help but stare at it.

"I'm not the only one dying." She waved weakly around them.

"But you're the only one dying I-" care about. He couldn't say it. It was a selfish thought.

"Then stay with me before I- look out!" The Apollo camper was already rolling out of the way heeding her warning, but Aden was too slow to react. With one final burst of energy, Agramon impaled Aden with his tail. He slumped onto a screaming Megan, and then her voice stopped, as the poison melted through her heart.

Aphrodite and Hades were quiet. Noticing their silence, Poseidon wandered over.

"Hey guys! How's my reincarnated son doing-IS THAT HIM?"

The love goddess nodded, mute for a bit.

"But-but-"

"Relax, you'll see him in the Isles soon." Hades patted his back.

"What?" Aden stood before the judges. He was waiting for Megan. He had died first, albeit a few seconds first, but there was all Megan's paperwork and such. "What do you mean this is my last life? You just said I can go to Elysium. So I choose to be reborn to go to the-"

"This is your third life." One judge repeated. "You're first life chose to be reborn three times, and this is your third. You don't remember because you drank from the River."

"Ow." Megan hit the ground beside Aden as she was thrown into the tent.

"Ah, Megara-" A judge greeted her.

"It's Megan." Aden smirked at her angry expression. She hated her real name.

"Well. We were just explaining to Aden Wall here-"

"I heard." Megan said. "While I was dying, I remembered something..."

"Mmhmm?" The Judges melted away and Hades himself sat at the table.

"Oh! Um," The two demi gods bowed.

"Yes yes, enough with the bowing. Are you ready for the Isles of the Blessed?"

"Wait." Aden took a deep breath. "Who was my very first life?"

"Why, Percy Jackson himself! And you," he pointed gleefully at a surprised Megan. "Were Annabeth Chase! Now, run along, the Isles are waiting."

Sitting on a picnic bench, a transparent, green eyed boy is holding a blue cupcake.

Approaching him, for the first time in years, is a grey eyed girl, grinning.

And as themselves in decades, they kiss.
