Here's another "Percy gets betrayed fanfiction" with slightly different pop culture shown. I don't own any of them. Just the plot.

The Fallen One

Chapter 1: The Void

Percy POV

"Perseus Jackson, today you stand for your trial." Zeus said.

"Wait, what? Why? I thought this was a regular meeting?" I asked.

"You have been accused of collaborating with Gaea during the Giant War. Anyone in favor of his execution?"

I paled when I saw many hands raised. I only had little supporters left. If you're wondering who my supporters are, here's a list.

From the demigods: Jason, Thalia, Piper, Leo, Nico, Hazel, Frank, Reyna, Hylla (for some reason) and half of Camp Jupiter, some Hunters and a few Amazons. (Calypso wasn't even invited.)

From the gods: Hera, Hades, Hestia, Artemis, Apollo and Hermes.

Everyone else raised their hands. I was pissed at the fact that even Annabeth turned against me. I caught her cheating on me with my annoying half brother, Lancelot "Lance" Fisher.

Zeus got up from his throne and pointed his Master Bolt at me.

"I am so sorry. Any last words, Perseus."

"Yeah. Four words." I said.

"I. Hate. You. All."

Zeus launched a lightning bolt and everything went black.

"Ugh. What happened?"

I woke up in some kind of hospital. It looked like it could house every medical tool of the trade. It's walls had images of planets and stars. Someone came in the door. I was astonished to this guy's identity.

"Luke? Where am I?" I asked.

"I see you're awake in good condition. Come with me. I'll explain where you are." he replied.

With that, I put on a jacket, shirt, pants and shoes and followed him outside.

"You're in the main barracks of the Void, Chaos' planet." he said.

"As in THE Chaos? Creator of All?" I asked, astonished.

"Yep."

I followed him to a giant target range the size of a mansion. There were targets everywhere. Several were burnt, cut or whatever.

"This is the Zephyr Long Range Company Barracks. They're a bunch of guys and girls that wield guns, bows, crossbows, bazookas, any kind of long ranged weapon. My wife leads this company."

"You're married?! To who?!" I asked, bewildered.

"A certain ex-Hunter of Artemis of cou-"

"You're married to Bianca?!" I cut him off.

"What? No! I'm married to Zoe! If you wanna see Bianca, I'll take you to her. Luckily, that's are next stop."

He took me afterwards to this giant dojo with a bunch of dummies scattered around. I saw a bunch of masked dudes fight unarmed. I paled when I saw the weapons on the walls: katanas, silenced pistols, sniper rifles, etc.

"Bianca's group consists of ninjas?"

"They're the Eclipse Stealth Company. Bunch of ninjas that rely on stealth."

Bianca turned to us. To my surprise, she looked like she was sixteen and her ninja armor had Hades' symbol on it, the same one I saw on Hazel.

"Percy!" I hugged her tightly.

"Why are you here?" she asked.

"Blamed for talking to Gaea. Annabeth cheated on me with my egotistic half brother."

"WHAT?!" Luke shouted. One of the ninjas that was balancing on a bo staff fell down.

"I am going to kill her!" Bianca screamed.

"Uh...Luke, anywhere else we should go to?"

"Yeah. Got it."

We went to some giant laboratory. It looked like that lab from Divergent. If you're wondering how I know that movie, Nico and Hazel made me watch it with them.

"This is the Enigma Science and Magic Company. You're in for a surprise when you meet the leader. She's not a child of Athena but she's as smart as one."

Luke showed me a young woman the same age as I am. She wore a lab coat and had a dagger strapped on her belt. She had black hair and ocean blue eyes.

"Hey, this is Perseus Jackson, son of Poseidon." Luke said to the girl.

"Ahem, more like ex." I said to him.

"I see. I'm Callista Frost, daughter of Oceanus. An honor to meet the famous Percy Jackson."

"Nice to meet you too."

Luke took me to another place: a giant hangar loaded with random spaceships, bombers and some kind of mecha (Imagine a ten foot ZAKU from Gundam SEED)

"Those guys are the Onyx Armor and Air company. They're self explanatory. Their leader, Skia Aeternam is a thought child of Erebus."

"Wow. Just, wow." I said.

"I know, right? Anyway, last one."

He showed me a giant barracks that was more luxurious than all the mansions in the world combined. I saw a bunch of guys wearing futuristic armor and they had different guns. I could've sworn that I saw most of their guns turn into giant swords (Lost Planet 2 Ex-NEVEC guys with Gun Swords)

"This is my group: the Abyss Special Forces."

"Ah. Perseus Jackson."

We turned to see a young man wearing a tuxedo full of moving stars, galaxies and planets.

"L...L...Lord Chaos." Luke muttered.

Everyone present, including me, bowed before him.

"No need to bow to me, everyone. Especially you, Perseus Jackson. I have an offer for you."

"What would that be, Lord Chaos?"

"How would you like to be the full commander of my army?"

"I...I accept, sir."

"Good. Now, onto some new weapons."

Chaos clapped his hands and a bunch of weapons and a black and red futuristic assassin outfit flashed in front of me. I saw one katana, two pistols, a guitar crackling with electricity and a suitcase?

"The katana is named 'Sparda' after a benevolent demon from another dimension. It can cut through almost any material. With this, you can unlock powers beyond your knowledge."

"The two pistols, 'Valiance and Defiance' act as one. You can do anything with your shots."

"With this guitar, the 'Nevan', the elements around you bend to your will."

"And this," he showed me the suitcase. "is your most powerful weapon. Watch this."

Chaos threw the suitcase in the air and it glowed mid air. He caught something in his hands: a long black and blue bazooka.

"That. Is. Awesome!"

"I named this thing 'Pandora'. It's every tool you need in one item. Now, for a code name. What do you think, Perseus?"

"How about Deathstroke?"

"Welcome to the army, Deathstroke."

The outfit is a color swapped DC Deathstroke outfit except with Assassin's Creed hood and robes (the Arkham Origins version with said differences)

Look at all those DMC weapons!
