A former test subject, now free, takes up residence in a strange town where almost nothing is considered abnormal. A year later, a young paranormal enthusiast spots two odd new satellites orbiting the moon and immediately makes plans to bring them to Earth, firmly believing that the two metal spheres are alien in origin. Because, after all, what else could they possibly be?

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? And did Black Mesa somehow cause the apocalypse? Meanwhile, Red and Purple wreak havoc on the universe, and Miyuki is not impressed. No pairings, mostly canon, post-Portal 2/The Trial.

Zim wakes up in a rather unpleasant manner to a rather unpleasant AI... (most likely a One-Shot)

(Previously GLaDOS' Trials) Aperture Science is a facility wrapped in mystery. Those mysteries can only be solved by a select few, Zim, Dib, and Wheatley aren't exactly the individuals that would come to mind andespecially not having to undergo odd new tests from GLaDOS called 'trials'. But this mystery has more to it than meets the eye with those three at the center. Has swearing.

These are the songs from portal's 1 and 2. Rewritten and a Invader Zim addition. Review

When Zim installs a hacking chip into Computer, he hacks into Aperture, and his life changes forever. Rated K plus for hints of Computer x GLaDOS

Wheatley was left stranded in space after the events of the Wheatley Laboratories fiasco. However, in orbit around the moon, he finds that it is not just him and the Space Core out here...

GIR somehow ends up in Aperture Labortories and insanity insues. ONESHOT!

GLaDOS needs new test subjects for further study in cooperation. The portal gun's success depends on it. When she send out the collector, Dib and Zim are in the wrong place at the wrong time. Portal 2 spoilers! Rated T for future language.

Rachel & her family live on a farm with a mysterious shed, not unlike the one seen at the end of Portal 2. Will eventually contain smeets

Conquerors look down on the integration of the new species, but just who has been conquered? One shot.
