Portal
Portal
This all mostly takes place after the events of Portal 2, and not much has changed to the core plot from the main games. Anything contained in side games (Like Lego Dimensions, Aperture Hand Lab, ETC,) will also be included, but not fully. This continuation also includes: Craig (Fact Core), Rex (Anger Core), CeCe (Curiosity Core), Pea (Party Escort Bot), and.... Cake Core (More to be possibly added) These following character interpretations are not owned by me but are however apart of Barnaby's story.
A year or so after Chell's escape and Atlas and P-Body releasing the stored test subjects from the vault, GLaDOS came to realize that having control over the entire facility is hard to do on one's own (though I doubt she'd let anyone know that) especially when your unable to move freely around and are confined to the ceiling -so with some digging, and the help of Atlas and P-Body, she was able to find blueprints and plans that where simply titled "Project: 8R-N4BY", a project that was meant to take her place before the 'incident', with this knowledge she'd oversee the construction of the android and allow him to be her second in command. Once constructed GLaDOS and the android (who named themselves Barnaby) began to form a Mother-Son relationship over time. Barnaby takes care of Aperture, It's tests, and most importantly it's technology - He creates new Test chambers or fixes old ones as well as oversees the tests going on in them, Checks around Aperture to make sure everything's in working order, and fixes up or creates Aperture properties. Barnaby spent a lot of time alone, he only really had his Rocket Sentry pet to be with...however, when going through some files he stumbled upon a few older model cores that peaked his interests, specifically one about that called itself "Wheatley" and how he was able to transfer himself into GLaDOS, it intrigued him greatly. Eventually through science fuckery Barnaby was able to get the core (and a few others) back to earth, where he would question him, and eventually bring him in to work at his side, and with that, plenty of time had passed and their bond would grow more deeper then most had expected it too (in fact, if you ask around, most would've thought Barnaby would toss the poor thing into the deepest parts of Aperture to suffer). Barnaby constructed Wheatley an android body similar to his own and transferred the core into that, once he worked out the kinks in Wheatley's new body and tested it properly, Barnaby would take that knowledge to construct bodies for other cores he deemed worthy of such a thing. Now with all the Cores he's turned android, he has himself a small team, ready to follow him into the darkest depths of science.
