A/N: Hey this is a story essentially about a Red Lantern Percy. I feel like there aren't a whole lot of Red Lantern stories out there and I wanted to write one. But instead of making my own character and falling victim to Author-Self-Insert itis, I decided to make this a crossover story with the Percy Jackson series.

In this universe, Camp Half-blood and Camp Jupiter both exist and only ever deal with magical threats. Demigods aren't all that powerful. Maybe just stronger than your average person with some magical ability. Percy and other demigods who are descendants of powerful Olympians are the exception. I imagine them to have the potential to be on par with Wonder Woman (shes the daughter of Zeus, it makes sense) but shes way older and has a lot of experience so of course she would have more powerful abilities.

Both the Justice League and Percy Jackson belong to their respective owners/companies.

-Chapter 1-

Today would have been our four-year anniversary, I thought to myself sitting across the TV watching a documentary on Coral Reefs with my stepdad, Paul. He and I shared a bucket of trail mix and popcorn and listened to a marine biologist talk about how further meetings with the Atlanteans has led to tremendous growth in aquatic science.

Paul turned to ask me, "So are you technically an Atlantean?" His tone was inquisitive and slightly cautious. He didn't really know how to bring up conversation about my other life.

"No, their an entirely different race. I'm technically human." I replied. I'd bet Annabeth would have started to go on about out the biological differences between atlanteans and humans. I could picture her now sitting right next to me, head on my shoulder, intently watching the documentary and pointing out inconsistencies.

Paul nodded taking in the information and we continued to watch the documentary in silence. Which was bad for me, the silence cursing my mind to have wandering thoughts. Thinking of Annabeth had brought on memories I'd rather not dredge up again. Like watching her die.

Two Years Ago

A few months after the defeat of Gaea a new threat rose to the occasion. As if there weren't enough world ending events already. These creatures called, parademons decided to show up and were soon followed by this evil warlord named Darkseid. Real nasty dude. Tried to take over the world, like evil villains tend to do. The only difference with this guy was that he was not of the magic world. He was a mortal alien and used mortal alien weapons. The Gods could not interfere, and no prophecy was given. By the time us demigods decided to take action Darkseid had already descended unto Earth and fought against a group of superheroes.

Chiron as well as Reyna decided against sending an army against him. He wasn't a god or a titan. It would risk too much to send more than six or seven demigods. So, we decided that while the superheroes would hold him off a small group of us would rush in and help in the fight.

But not all went according to plan. We had attacked him with everything we had. But to no avail. Darkseid had grabbed Annabeth by the throat. I had tried to summon every ounce of power in me to stop him. Tried to summon the water in the air. Shake the earth beneath my feet. But my abilities failed me. I had no idea why. Darkseid had choked the life out of Annabeth and I was powerless to stop him.

Present Day

The documentary was ending, and I decided to refill my cup with water. I walked into the kitchen and turned on the faucet. Suddenly the water spewing downward shot up and formed a misty rainbow. The image of my father, Poseidon, appeared before me.

"Dad?" I said surprised.

He had on a grim smile and nodded his head before saying, "Hello Percy, its good to see you again." He shuffled a bit and looked off toward his left in worry before turning to face me.

"What's wrong?" I asked.

"Don't worry, the world isn't in peril today," he said reassuring. "The Council requests an audience with you, Percy."

Immediately my gut twisted in worry. What did I do wrong this time? "If this is about that pie to Artemis's face, I just so happened to be in the same room when it happened. I swear."

Poseidon chuckled halfheartedly and said, "No, no, its not about that. But you need to arrive tomorrow at dawn. That is when the council will be held."

"Alright dad, I'll be there."

"Good. See you then." And he cut the message. He seemed way more guarded then usual. Maybe it was just my imagination. Or I was just tired. Probably both.

"Who were you talking to?" I heard my mom ask from behind me. She had just come out from the bathroom.

"Oh, it was dad, he said that the Council wants to meet with me."

A look of worry and mild annoyance crossed my moms face. "What for? Is the world ending again?" She asked in a huff.

I sighed and said, "No its not that mom, don't worry. I'm not sure what's going on but I don't think anyone's lives are at stake."

My mom, gods bless her, took a deep breath and gave me a tight hug. "Please Percy, if its another quest… You've been doing so well in college."

I smiled at my mom, "I know. I promise if my help isn't desperately needed, I won't go on any quests."

She exhaled with relief, "Good. Good. Now is that documentary over? Can we watch an actual movie now?"

A/N: Hey again, if you have any questions about this crossover universe feel free to leave a comment and I will definitely answer it, this was just a haphazard idea so if you have any suggestions to how some aspects of this universe should work please let me know! Also I haven't read Percy Jackson in a while so if there are any inconsistencies, feel free to point them out.

I based this story on the Justice League: War animated movie and the good ole Percy Jackson series.
