After Caroline discovers her 'parents' to be Black Mesa spies, Doug Rattmann hides young Chell in Old Aperture before she's sealed off and presumed dead. Years later, she's back, and her resurfacing could lead to Aperture's downfall. A Portal prequel about what it truly takes to have a shot at redemption.

Petunia sends a baby Harry to her aunt, living in America, Caroline Evans. Some years later, Caroline becomes GLaDOS, and only Harry stops her from her rampage. Now, Harry is eleven, and he's heading to Hogwarts. Of course, with an amoral scientist/computer for a great-aunt and a mute big sister, the question is not whether he is ready for Hogwarts. Is Hogwarts ready for him?

When GLaDOS scans her databases, she can't help but feel bile fascination at the document she finds. What ensues is GLaDOS and some other familiar faces reeling over one of the most infamous Portal fanfics ever written.

A retelling of the Portal and Portal 2 story set as a Medieval fairytale.  Written by ElvenWhovian with contributions by Starry-Nightengale.  All Valve characters belong to Valve. All Blue Sky influences are inspired by Waffles' excellent work.

Three years after Chell saves Wheatley from being launched into space, he means to help her escape the facility and shut down GLaDOS for good—but after finding a lost secret, hidden away within a condemned Test Shaft, is she really the only AI they need to be worried about? This is a story of redemption, adventure, and finding friendship in unexpected places.

Last wishes should always be fulfilled. Sometimes, this is easily accomplished. Other times, not so much. Human!Wheatley

Chell fights her way through Aperture again, with help from mute!Wheatley and the Fact and Adventure Spheres. The turrets have formed an odd society, and Atlas and P-body lurk around every corner. Inspired by Portal Kink - lots of them.

GLaDOS was originally a human, that much is certain. How much humanity remained in her after she was transferred to a computational entity and dedicated to Science, however, is a lot more disputable. Rated for swearing.

Wheatley had never been anything other than a robot, but he was given something most AIs never had - the ability to change who he was. Rated for mild, humorous swearing, most of which only British people would consider inappropriate.

Post-game. As she regains control of Aperture, GLaDOS thinks of a far better punishment for Wheatley than floating through space for eternity. After being transferred back into his old human body and let loose in the facility, Wheatley vows to help Chell escape Aperture once and for all, but GLaDOS has other plans for the pair. Wheatley/Chell

When a dangerous mute lunatic is put in control of the Aperture mainframe, GLaDOS and Wheatley are forced to work together to save science.

Meteors, signals, apologies, and that tricky little thing called humanity- four years after the events of Portal II, Wheatley's been handed a second chance, but it's not going to be plain sailing…

A contrite Wheatley makes it back to Earth where he finds a Chell unwilling to forgive him, a Scientist willing to help...and well, if the results of giving Wheatley agency and power were disastrous the first time, you can bet he's learned nothing.

You don't escape from the insane facility of Aperture on tenacity alone. It takes a generous helping of bravery, wits, and sarcasm. And sometimes just a little bit of help from the last expected source.

GLaDOS has several brain-dead test subjects on hand, but a bunch of handy constructs to fill their mind. Their minds reawaken back to their previous lives. Factventure multi-chapters

Chell is quite far along, and Wheatley is worried. No apologies for the blatant fluffiness of this one-shot, written for my bff who requested something with a pregnant Chell. Human!Wheatley, post-game. Same continuity as Blue Sky- well, if you like!

While riding the rail car through Aperture Science, the workers would hear Cave Johnson's Official List of Rules. [Comedy! Feel free to add funny suggestions: they might make it in!]

They designed the machine to look like Science incarnate. A short fic on the GLaDOS machine, and the woman who would be contained within. Slight Cavoline, but more tragedy than anything else.

In which Aperture Laboratories has a small pharmaceutical contamination problem, and Wheatley has the worst job interview in history. Short and dirty -and slightly silly- one-shot zombies!AU.

The crew of the USS Enterprise, during a lull in their adventures, comes across an artifact of Earth's past. What secrets does it hold, and what dangers?

Wheatley's never really understood why humans have so many useless parts. Hair, eyebrows, fingernails...and lips. What did lips do, anyway? Of course, maybe bringing it up around a certain mute lady isn't the best idea... oneshot
