Disclaimer: I don't own Portal. Valve owns Portal. Same goes with Half-Life. Also Valve property.

I guess you can call it a crossover, even though them being in the same universe was ALREADY Canon.

Alright, So I have gotten a surge of new ideas for Fanfic in the last year. So, so many of them I haven't even written yet! I haven't been updating PJF or MBN7 very much because my Mother's computer broke and she keeps kicking me off of mine. But, it is fixed, and I can use my computer whenever I need now! So, now, I bring you this new Portal/Half-Life fanfic, which takes place seconds after the Co-op mode of Portal ended for my OC's (and Atlas and P-body), but for Chell and the Half-Life people, it is just after Single player mode of Portal ended.

Anyway, In this fic, Portal 2 is NOT 200 years after Portal 1. The announcer robot was just broken. It has actually only been 10 years. But still a long time.

Chapter 1 focuses on one of my OC's, one of the millions of test subjects woken by Atlas and P-body.

Wait, What?

Nick woke up in a motel room. He still felt half asleep. In fact, he didn't remember this motel room. He was an employee of Aperture Science. Then… She was activated. Bring your Daughter to Work Day was a bad day to activate a potentially deadly computer. Everyone was ran through test chambers, testing out the Handheld Portal Device. She flooded the enrichment center with Neurotoxin. The 10% who had survived (about two million people) were put into Cryogenic Storage. After a few days, the resonance cascade thing happened at Black Mesa, and the media was no longer concerned with the trapped Aperture employees. And now, he was here.

Her voice came out over the intercom. "Nicholas Castros? Are you awake?" She asked. "How are you talking to me from a motel room, GLaDOS?" He asked her. "Oh, you remember. Well, you are still in Aperture Science. Just open the door!" She said excitedly. "Oh, by the way, sorry about the killing spree. I mean it. Turns out killing 90% of the employees leaves me with fewer test subjects," She said. Nick shrugged, and opened the door. He saw millions of rooms in an open space, just hanging there. There were some doors open, many not.

The ones with open doors were just there, but the ones with closed doors had glass rooms with a toilet and a table with some things on it underneath. He remembered them. He hated them. They had tracks leading down into test chambers. "So… I guess you are going to be testing me, then?" Asked Nick. "Yep! And no Portal guns this time…" She said. Nick wondered why she seemed… scared of them. "When do I start?" groaned Nick. "NOW!" She yelled, and the floor beneath him disappeared. He was in a glass room. Like the others.

The rooms started to go into a test chamber. This was… Different than usual.

There was no Portal to let him out. Instead, there was a hammer. He grabbed it, and swung. The glass shattered. He walked out, and the door opened. There was a switch, a button, a door, and a Weighted Storage Cube dispenser. He pressed the switch, and the dispenser dropped a cube, and another switch came up. The dispenser continued to drop cubes into a pit. He got frustrated, and tried to see what the switch did. Suddenly, the boxes started being covered in Cave Johnson's Repulsion Gel. Nick was confused. But he didn't mind. He grabbed a bouncing box and washed the gel off with a water spout nearby. He put it on the button, and the door opened.

After he walked through the door, he saw the recognizable lift. He walked in, and ascended to the next level. He saw many other test chambers, with people scrambling around in them. He even saw two robots with portal guns at some point. Nobody else had portal guns. Anyway, He got to his floor.

There was a device throwing repulsion gel around. He walked over to the device and confetti fell around him. "Congratulations. You now are in possession of the Handheld Gel Device. For now, you can only use Repulsion Gel, but there will be Propulsion Gel in future tests. I'll explain how it works: It has a portal from a portal gun inside, and the connecting portal is connected to a Repulsion Gel Manufacturing Plant. Once you can use Propulsion Gel, switching the device to PG will move the portal to a Propulsion Gel Manufacturing Plant. Anyway, complete the test chamber." She said. He bounced around between two lines of Gel, and got to the end… except there was no door.

"Oh… Did I forget to put a door there? I'll just let you through the wall…" She said. The panels opened, and he went out onto the catwalks. "I'll need you to come to my chamber… NOW." She said. Nick cowardly walked through the catwalks to GLaDOS's chamber. She was scarier than before. The room had black panels instead of white, and was better lighted, giving the impression of an interrogation room.

"Okay, I forgot to give you something I gave everyone else, something that is required for testing. You need a Personality Core Helper."
