The following story is a cross between two of my (many) favorite things: Teen Titans and Halo. This will only cover the original Halo, not Halo 2 or Halo 3. A story covering all three of those games would be pretty long. The main character in this fanfic will be Cyborg, probably the least favorite Teen Titan. This doesn't mean that the other Titans won't be in this fic though, they will all be making an appearance.

While I was writing this, I was both playing Halo and reading the book Halo: The Flood, so I think this'll be pretty accurate.

Disclaimer: I don't own Teen Titans nor Halo.

Chapter 1:

THE PILLAR OF AUTUMN: REVEILLE

Cyborg was roused from his sleep by the chilling cold. He shivered. However, he didn't try to open his eyes, he just wanted to lie down and try to fall asleep again. But the temperature didn't help with it.

'Why is it so cold?' Cyborg thought, 'I hope I don't have to fix the air conditioning again…'

That was when he heard someone speak, "…cycle complete. We're showing green across the board."

"What?" Cyborg said, snapped open his eyes. He realized he was not on his recharging station anymore. He was in some kind of tubular metal pod with a viewing window on the front, just at his head level. Through the glass he could see a man in a jumpsuit. The man was looking at him. Vapor rose from vents into his face, then diffused into the air.

The whole side of the pod in front of Cyborg opened from the bottom and hinged upwards. Cyborg knew this must be a dream. No one would wear a jumpsuit like that.

"Sorry for the quick thaw Master Chief, but things are a little hectic right now" the man said, stuttering a bit, "The disorientation should pass quickly."

"Welcome back sir. We'll have you battle ready stat," another man in a jumpsuit said, as he raised his arm in the air to get Cyborg's attention. The man was behind a large glass viewing window positioned on the wall of the room Cyborg was in. Cyborg could see several computer consoles near the man behind the window.

'Yeah,' Cyborg thought, smiling, 'This must be a dream.'

"Chief, please look around the room," the other man told him, "I need to get a calibration reading for your battle suit's diagnostics."

"Okay," Cyborg replied. He played along with his dream. Eventually he would wake up. The only thing he could do was enjoy his dream while it lasted. He looked around the room and cracked his neck.

"Good," the man commented, "Thank you sir."

"I'm bringing your health monitors online sir," the man behind the window informed Cyborg.

'Health monitors… heh' Cyborg thought.

"Vital signs look normal. No freezer burn," the orange-jumpsuit man stated, "Okay sir, go ahead and climb out of the cryo-tube."

Cyborg got up and exited his cryo-tube, which he noticed was leaning against some metal columns in the middle of the room he was in.

"I gave you a double dose of a wake-up stim," said the man in front of him, "Take a quick walk around the cryo-bay and join me at the optical diagnostics station when you're ready."

Cyborg did as he was told. He walked around the room, seeing many more cryo-tubes like the one he was just in. He even jumped around like a lunatic, then he went back to the man, and stood inside a red square on the floor, thinking the man must want him to stand there.

"I know the ordinance sects usually take care of your targeting sensors, but we're short of time, chief," the man said, "Just look at each of the flashing panels to target them. When you lock on, it'll change color."

Cyborg obeyed and looked at each of the red squares placed on the four ends of a cross hanging from a column in the middle of the room. As he did, the squares changed color from red to green. After he finished, the man commented on his actions again.

"Okay, that looks good."

Then the other man behind the window spoke, "Sir, I'm getting some calibration errors. I'm going to invert your looking pitch, so you could see if you like it better that way."

Cyborg chuckled a little. This was one crazy dream.

'Inverting my looking pitch? Where'd that come…'

But his smile disappeared when he tried to look up, but ended up looking at the ground.

"Try targeting the flashing lights again."

Cyborg tried looking up and down again. His looking pitch was inverted. He hoped the dream would end soon. He was getting a little dizzy. He didn't notice that as he looked up and down, the lights on the cross again changed color.

"Is that better or should I switch it back?" the man asked.

"Umm, switch it back?" Cyborg answered. Immediately his looking went back to normal.

"Now should I leave it like that or should I switch it back?"

"Uhh… leave it I guess" replied Cyborg.

"Okay, I'll leave the pitch at normal, but if you want, you could change it yourself later."

"Sure… I won't try that soon."

"I'm ready for the energy shield test now," the man continued.

"Please follow me to the energy shield test station," the man in front of him said.

A female voice spoke through an intercom, "Fire teams, report to defensive positions alpha through sierra. Sensors show inbound Covenant boarding craft. Stand by to repel boarders."

Cyborg followed the man in jumpsuit to the other side of the room. "Energy shields?" said Cyborg, "You're kidding, right?"

But the man didn't seem to notice. Cyborg then stood on another square on the ground, this time with a yellow and black outline. It was under some sort of strange machinery. He wasn't sure what it did, but the machine didn't look dangerous.

Once Cyborg positioned himself, the man guiding him spoke to the other man.

"Okay, bring his energy shields online please."

The man pressed a button, then the machine started spinning around Cyborg slowly, humming a low buzzing noise. It was emitting some kind of faint gold glow, and it seemed to be charging Cyborg up. He saw that his body's energy readings were coming off the charts.

The man behind the window said, "All right. Shields read as fully charged."

"Okay sir, bring them down to test the automatic recharge," the man told Cyborg.

Then the machinery spun even faster around him, and its humming became even more intense. The glow changed from gold to red. Cyborg felt uncomfortable. He felt trapped. Then something stinged his behind.

"Ouch!" Cyborg exclaimed, "What the heck was that!"

He then checked his energy readings, and they were back to normal again. But they slowly started to rise once more.

"This sure is weird…"

The man behind the window said, "Shield charging normal. We're showing green across the board."

'What did I eat last night?' Cyborg thought, 'I'm sure I cooked the food right…'

Then another voice spoke through the intercom, this time someone elderly.

"Bridge to Cryo-two, this is Captain Keyes. Send the Master Chief to the bridge immediately."

The man in the room with Cyborg complained, "Captain, we'll have to skip the weapons diagnostics and I…"

"On the double crewman," the voice interrupted.

'So that's what this is,'Cyborg thought, 'This must be some kind of spaceship, and they're part of the crew. But why am I being called Master Chief? This is both cool and weird.'

"Aye aye sir," the crewman replied, then looked at Cyborg, "The skipper seems jumpy, we'd better get moving. We'll find you weapons later."

"Okay, I'll leave the self-diagnostics running at least," the man behind the window said.

"Weapons?" Cyborg stated, "The only weapon I need is right here!" He raised his right arm, but again the crewmen didn't notice, as if they were just robots.

Cyborg heard a loud banging sound. He looked around to find the source of the noise when the man behind the window yelled.

"Oh my God! They're trying to get through the door!" the man panicked. Then a door inside the room he was in exploded open, and a tall alien in shining red armor came through, firing what looked like a plasma weapon at the man. It hit him thrice in the chest, blood spattering on the viewing window. He then collapsed on the floor.

"Sam! Sam!" the other crewman yelled. Then he faced Cyborg and said, "Come on, we've got to get the hell out of here!"

He ran for a futuristic-looking door that slid open just as he went near it. Cyborg followed him, thinking that this dream was getting a little exciting. He couldn't wait until he saw what other crazy thing would happen. Maybe when he woke up, he would make a video game out of his dream.

"This way!"

After they both went through the door, they ran through a metal corridor toward another door at the end. But just as they arrived, there was explosion from the side. The explosion rocked the whole corridor, hitting both Cyborg and the man he was following, killing the latter.

Cyborg again felt a stinging on his body, like the one he had before. He looked at his energy readings again. They went back to normal, then rose off the charts again. Cyborg doubled back. He sure wanted this dream to end soon. That explosion sure felt real.

When he walked back to the other side of the corridor, he saw an opening on the wall to his right. His instincts told him to go through there, so he did. He jumped over some thick cords on the ground then turned right at the next corridor. He went to the door at the end, and to his surprise it opened just as he approached it. As he did, he saw a dead crewman by the door. He went through to a shorter and more well-lit corridor, and walked toward the door straight ahead.

But then there was another explosion, this time right before the door he was going for. Fortunately, this time he wasn't hit, and he went through the door. When he did, he saw he was in a dark chamber. To his left, there was a some kind of blast door which was slightly open. Someone was screaming on the other side. He crouched down and went to the next room. There he saw two other crewmen, who crouched down with their hands over their heads. Then there was a bright blue explosion that killed the man to his left. Cyborg looked, and saw two more aliens like the one he saw earlier, firing with their own plasma weapons. This time the aliens were blue. Blast doors closed, trapping the aliens in their own little prison.

Cyborg turned around and saw some more blast doors closing. He then walked toward another doorway and into another corridor. He saw, painted on the floor, a blue arrow pointing down the corridor with 'BRIDGE' in the middle. He remembered the voice in the intercom, and followed the arrow.

When Cyborg got to the end of the corridor, the door opened, revealing yet another alien, right in Cyborg's face.

"Yikes!" Cyborg yelped. Then, as if by reflex, he aimed his arm at the alien as he transformed it into a sonic cannon. But he realized the arm didn't change into one. He gulped. The alien roared and shook its entire body as if it was storing some kind of immeasurable anger. It was about to charge Cyborg, but guns fired on from the corridor to Cyborg's left, hitting the alien and sparking some kind of energy shield it was wearing. The alien fired back, then moved backwards from the barrage of bullets. Doors close, then the alien was trapped like the others.

Cyborg went to the source of the arms fire, and saw two soldiers clad in grey armor. Their helmets had a small green monitor in front of one eye. One of them spoke to Cyborg.

"Chief, Cortana says to get to the bridge, double-quick," the soldier told him.

"Cortana? Who's Cortana?" Cyborg asked, but the soldier didn't respond.

Cyborg proceeded down the corridor, until he went through another doorway and saw a kind of barricade to his right, right before some blast doors. A crewman was behind the barricade, firing at some other aliens in the other side of the blast doors. This time, Cyborg saw one tall alien and three other, shorter aliens. Two were in orange armor and one was in red. More blast doors closed.

Cyborg walked to another soldier, and the man spoke to him with an Australian accent.

"Sir, the Captain needs you on the bridge, ASAP. Better follow me."

"Lead on."

The solider turned around and walked through another doorway into the next room. As Cyborg followed him through the room and toward a door at the end, he saw several wounded soldiers sitting on the floor with blood all around. Cyborg winced. He was squeamish around blood.

When they went through the door, the soldier Cyborg was following shouted, "Get clear Chief!"

Then there was another blue explosion in the next room. Two more crewmen were firing pistols at aliens. Even more blast doors closed, then Cyborg followed the soldier to the back of the room, toward another door. Before the door, on the ground was the arrow with the word 'Bridge' again.

They went through some more corridors, then the soldier stopped in front of an opening into another room.

"Captain Keyes is waiting for us, sir!" the man said. Cyborg nodded to him, then walked into the room, past a few more crewmen on computer consoles, and toward an old man standing before what Cyborg thought was a glass tactical display, because of the circumstances. He walked nearer the grey-haired man, then coughed.

"Captain Keyes…?"

The man turned around and greeted Cyborg with a handshake, "Good to see you Master Chief, things aren't going well. Cortana did her best… but we never really had a chance."

"Who is this Cortana anyway?"

Then a hologram appeared over a pedestal to the captain's right. It was in the shape of a human, but everything was in violet, with strips of data covering the body and circling around it. It was naked, and had hair that almost touched the shoulders. The human hologram had its back to Cyborg. It spoke in a female voice similar to the one Cyborg heard through the intercom earlier.

"There's a dozen Covenant ships here," the hologram said in a throaty voice, "Anyway, we've got three… I mean four kills."

The holographic woman turned around, and looked at Cyborg. They looked at each other eye to eye for some time. Cyborg saw that the girl seemed familiar. But the strips of data running through her skin obscured her face. After a few seconds, the two finally recognized each other, and Cyborg gasped and staggered back in shock.

"RAVEN?!"

"Cyborg? What are you doing in my dream!" Raven yelled, also in a state of shock.

"I could ask you the same…" Cyborg noticed Raven's… figure, "Oh my gosh! You're NAKED!!" Cyborg then began to giggle.

"Grr…" Raven growled, covering her privates, "You're lucky I don't have my powers right now!"

"You don't have your powers too?" said Cyborg, still chuckling a little, "I'm getting the feeling that this isn't a dream."

"Me neither."

But they were interrupted by an explosion that rocked the whole ship. The whole crew stumbled, then returned to their posts.

Captain Keyes recovered his balance and shouted, "Report!"

Raven answered, "I don't know, maybe it's one of their boarding parties."

An officer nearby turned his head toward Raven and said, "Ma'am! Fire control for the main cannon is offline!"

"I don't think this ship has any more weapons," Raven said, looking at the Captain, then at Cyborg. She quickly covered herself with her hands.

Captain Keyes said, "All right. I'm initiating Cole Protocol, Article Two. We're abandoning the Autumn. That means you too, Cortana."

"My name's Raven," Raven told him, "And while you do what? Go down with the ship? I have no idea why I just said that."

"In a manner of speaking," answered the captain, "The object we found, I'm going to try and land the Autumn on it."

"But won't you die?" said Raven.

"I appreciate your concern Cortana, but it's not up to me. The Protocol is clear. The destruction or capture of shipboard AI is absolutely unacceptable. That means you are abandoning the ship. Lock in a selection of emergency landing zones and upload them to my neural lace."

Raven nodded, "Sure." Then she faded away.

"Which is were you come in, chief," Captain Keyes said, turning toward Cyborg, "Get Cortana off this ship. Keep her safe from the enemy. If they capture her, they'll learn everything… force deployment, weapons research… Earth."

"Well that's… logical I guess."

Raven reappeared on the pedestal, her arms crossed.

"Cortana, are you ready?" the captain asked her.

Raven looked around at the Bridge's interior. Then she spoke, "Do I at least get some clothes?"

Keyes went nearer to the pedestal Raven's hologram was on, then pressed some buttons. Raven flickered out, then the captain took out a small blue chip and showed it to Cyborg.

"Good luck Master Chief."

Cyborg took the chip, then placed it into a slit on his arm. He felt a cold sensation over his head, then felt a presence together with him in his body. With Raven being inside him, it felt like his personal space was being invaded.

"So this is your body. You made fun of me earlier… now it's my turn."

Cyborg cringed.

"Don't get any funny ideas."

Haha… that was fun. In case you were wondering, I was only playing Halo on easy while I was writing. Sure, call me a noob, but it's pretty difficult to write a script of the game with almost every event and spoken statement when it only takes about five shots to get killed. On easy, recording everything is quite easy.

As you have read, Cyborg took the place of Master Chief, while Raven took the place of Cortana. So the other Titans will be replacing some other characters. Try to guess what Beast Boy or Robin or Starfire will be.
