"talking"

'Thinking, notes'

*What is happening*

[Author's Notes]

I walked over to the camera and turned it on. "Hey guys! Welcome to my first recording. I'm here to tell you guys a little about myself. Firstly, my name's Felix. Secondly, I am 32. Thirdly and lastly, scout is going after me. *Scout wraps her arms around my neck*" I said. "Hey there sweet cheeks. *kisses me* Hey there Internet people. *waving at the camera*" Scout said grinning.

"Oi! Leave him alone scout!" medic said. I smiled. "It's okay doc." I said. Medic went back to her paperwork. I sighed. "the second recording you ruined scout." I said taking out a pair of bonk and passing one to scout. "What? It's not my fault you're good looking." She said taking a sip of bonk. She grinned at me. "Wha-" I got cut off by scout kissing me. I deleted the recording. I sighed.

"Something on your mind sweet cheeks?" She asked sitting in my lap and leaning on me. "Nothing." I said. "Come on. I know you like me." She said nuzzling her head on my chest. "Only as a friend." I said with a weak smile. Another pair of arms wrapped around my neck. I turned my head to see medic. She smiled and pecked my cheek. I blushed. She went back to her paperwork.

So far, scout and the medic are the remaining members of RED. BLU have all their members. I fairly fight them with a double-barrel scattergun, desert eagle and nunchucks. I'm trying to regroup the RED members back together. Scout is trying to 'do' it with me. I refused her because this is a teen rated story. They both like me. I'm trying to make videos, but scout ruins it to tease me. Once, a FREAKING KINETIC BOMBARDMENT [Which can go as fast as MACH 10. MACH 10 = 7672.96 miles per hour. Or 12348 kilometers per hour. So you know how fast it is.] fired upon on both RED and BLU. I could barely aim at them.

I can run faster than scout. She can run 9 meters per seconds, while I can run 343 meters per seconds. The fastest I can barely run is MACH 1. [MACH 1 = 770 miles per hours. Or 1234.8 kilometers per hour. So you know how fast that is.] I could run that fast for two hours.

Hours later.

"Listen, I'm trying to help you for God sake!" Scout said pacing back and forth across the room. I took a deep breath. "I know you are trying to help me. I'm going to need you to stay here and help the medic. Until then, I'll be ba-" I got cut off by Scout hitting me across the room with a baseball bat. I smiled as I gotten back up and teleported behind Scout.

"Don't you dare do that again. I'm stronger than you think. I'm here to help you regrouping team RED." I said encasing her and teleporting her to her room. I was tried. I climbed on the bed and fell asleep.

Dreams land

I was standing on the roof of a building seeing a female titan staring at me. She stuck her hand out, the titan steamed and turned human. I remembered her name. Erian. [Female version and name. Sorry if it's a bad name. I'll try to get their name to sound female-ish] She ran and embraced me. I hesitantly hugged her back. I smiled and she looked into my eyes. She still have the necklace around her neck. She grabbed my face and kissed me. I blushed. She giggled. A pair of arms wrapped around my neck. I turned my head to see mikasa smiling at me. A colossal titan appeared and I made my hands glow white making Erian and Mikasa let go of me. I smiled as I made blades, teleported to and destroyed his nape. He fell down backwards crushing the remaining smaller titans. I smiled at the success I made.

Real world

I woke up with Scout laying on me. Her head on my chest. I smiled and kissed her head. She flutter her eyelashes open and looked into my golden and Platinum eyes. She nuzzled her head on my chest. For a second, I saw Erian nuzzling her head on my chest.

Hours later

I've been here for a month. Scout is still trying to 'do' it with me. I just glared at her and teleporting her to her room. BLU is still a pain in the ass. Especially the BLU spy. She is making herself into scout making me think that's she's scout.

"Listen, I'm going to get their intel." I said to scout and the medic. As soon i got out the room, everything went black. I woke up in the room. I groaned. I gotten back up and teleported behind the sniper. "hey mate." i said filling him with bullets from my pistol.

Scout got the intel and ran to RED base. I covered fire to distract them from shooting scout. It did work. We won and yadda yadda yadda. Scout ran and jumped on my back. I sighed and walked to the base. I was

As I went in my room, i gotten hugged tightly. I look at the one that hugged me. Erian. She's still at my chest. I smiled and hugged her back. Mikasa was on my bed. So was Armin. They both were smiling at me. I smiled at them. Both Mikasa and Armin walked over and hugged me.

They all still have their necklace i gave them. I asked them why they were here. They told me they missed me. I weakly smiled at them. Erian still have the ability to turn into a titan. I teleported they back to them back to their house in San Diego, California.

Dream land

I ran away from the creatures that's chasing me. The taller is blue and the shorter one is yellow. I tripped and fall face first in the cold ground of Alaska. I turned around. Blue grabbed my shirt and threw me into a tree. I fell and got a backflip kick to the jaw. My breath is heavy. I got up slowly and took out a prototype grenade. I smiled insanely and pulled the pin. A flash of gold went and go. Photos. I sighed as I took out a knife and encased it with my powers still smiling insanely. The knife increased in length. It ended slightly longer than a katana.

Real world

I woke up drenched in my sweat. Everything in my room were destroyed. The headphones that Sofia gave me is not broken. I sighed in relief. She paid lots of money for that. She is obsessed with nekos. For her 18 birthday, I cosplayed a neko for her. She embraced me with tears of joy. I chuckled and hugged her back.

A sharp pain was on my right arm. I turned my head to see medic with a needle saying 'pain and stress relief' Everything that bothered me went away. She took out the needle, placed a bandage where the needle was, gave me a lollipop and placed the headphones on me with a smile.

I took a slice of toast and ran to the room for battle. The two of them were there running out the room when the battle started. I switched the nunchucks for a knife. BLU demowoman forgot her bottle of whisky. I grabbed it and downed it as I took my knife out. I smiled insanely and encased the knife making it slightly longer than a katana.

BLU demowoman took out her sword and ran at me. I insanely smiled and sliced at her direction. A sphere of my power flew at her hitting her square in the chest. She disintegrated in seconds. Heavy stared at me in fear. I sliced at her direction and she disintegrated as well. A flash blinded me for a second. I looked where it came from. RED medic was the one who did it. She shot me with a needle. I felt drowsy in seconds. I fell on my back.

Meanwhile in RED base, medic room

I woke up in a room. A blinding light was above me. My vision is blurred and I can see red and blue color. My vision cleared, I turned my head to see both RED and BLU medic walking around to get their tools. I groaned and they looked at me. The BLU medic stabbed me with a needle. I fell asleep.

Dream land

I woke up on the beach that had the chair and side table. A note was pinned on the table with a sword. I raised a eyebrow in confusion. I teleported to the note. It says, 'Felix, I know you can only access this place by dream. Next time you're here, Wait for me.

~Erian'

I smiled and sat down on the chair. It seem like it been hours. I felt someone tapped my shoulder and turned my head to see Erian smiling. I woke up.

Real world

I woke up in a body strap. I struggle against it strap. I sighed and made my hands glow white making it burn. I finally got free from it grasp. I walked over to the door. I made my right hand glow white making the hinges melt. The door fell down from the inside. I walked out the room and teleported behind the RED medic.

"Hello." I said taking her out. I found out that they took my DNA and test it with another person. The said person died due to my DNA tearing the the person DNA apart. I was confused about the DNA tearing another person DNA. I turned around to see both RED and BLU aiming their guns at me. I sighed, took out my shotgun and quickly put it together, encasing it and fired it. The one that got hit, disintegrated from my powers.

They retreated to another room. I teleported away from death Valley, California. I went to San Diego, California to see Erian, Mikasa and armin. I walked to their doorstep and knocked on their door. It been a minute before the door opened. Armin opened the door surprised to see me. I smiled as she hugged me tightly. I hugged her back.

"What brings you here?" Mikasa asked me. I shrugged and letting Armin go.

"Just wanted to see you guys again." I answered her smiling. She had a bothering look in her eyes.

She made a gesture to follow her. I did and she showed me a spartan helmet.

*flashback when Felix was still a spartan*

"6! Come on! Get on the pelican!" I yelled onto the com to 6. He didn't responded. 'Crap. Now I have to get him.' I thought running and shooting the covenant left and right.

I spotted him dying on the ground with energy sword gashes. "Come on, come on, you can to it 6." I said healing him. He didn't have his helmet with him.

A giant wave of air blast past us as the giant ship leave Reach. "We can survive this Felix." 6 said getting up. I chuckled, took out my pistol, aimed at him and twisted it to give it to him. He took it and ran with me.

*flashback ends*

I stumbled backwards and tripped onto Mikasa bed. She looked at me as if asking me that I'm okay. I nodded. She grabbed my arm and lifted me up.

I thanked her for helping me. She softly smiled at me. She left me in her room. I sat down on her bed frame and looked at the spartan helmet. There's a note inside his helmet.

[Hey guys! Welcome to my first crossover! I like to thank Theneo for helping me. As usual, review, favorite and follow. Thanks for reading this chapter.]
