"Cave Johnson here! I have been informed by some pencil pushers that I need to do a documentary on a new creature we have made called Inklings. Usually I wouldn't bother doing this and would've just fired them by now, but I have a week to spare until the moon rocks I ordered get here."

In an obvious and popular matchup which I'm surprised had yet to be made as a satisfactory Epic Rap Battle, Portal's quirky antagonist goes up against the malevolent supercomputer of System Shock fame, with a surprise appearance by the most vile machine ever conceived. Video: /watch?v NFZiKUCVG6Q

A Portal / Night Castle (Trans-Siberian Orchestra album) crossover - Chell wakes up to find herself washed ashore on a beach, with a mysterious castle awaiting her on the cliff top... A random, fairytale-like one-shot. Chelley, both Android! and Human!Wheatley

Once upon a time, an angel went to a different reality. And things were never the same. (An experiment in crossovers)

Seiten Taisei couldn't remember why he was in Aperture Science Laboratories, but that didn't stop him from having fun with the portal gun.

...at the Aperture Science Testing Facility last Tuesday

Tony Stark finds himself advising JARVIS about his new girlfriend. JARVIS' new girlfriend, that is. Movie-verse Iron Man. Rated T for innuendo and colorful technological metaphors.

After being released from Aperture, Chell has reintegrated with hyuuman society, but something is wrong. Why is everyone so stupid? Is that green kid really an alien?

"You can have whatever you want if you just wish for it." It's a tempting proposition, but it comes with consequences. Chell knows them well, but she may be the last hope of a divergent timeline. Portal/Madoka fusion AU. Humanized cores and GLaDOS, for a given measure of "human." Spoilers for Madoka Magica.

GLaDOS realizes that maybe she can't just delete feeling from herself, that she needs that mute lunatic in her artificial life Yeah, it's not actually a crossover, Portal and Half Life are in the same Universe
