The Interview Core

Interview Core

“

Don't flatter yourself, you never were a functioning part of anything. — Ego Core describing the Interview Core

”

The Interview Core is a corrupted personality core who appears in all episodes of the series. He escaped incineration by GLaDOS and found himself on a table, setting the literal stage for the talk-show. As the host of The Underground, the Interview Core is responsible for interviewing his guests and giving answers to his possibly empty audience. He also has a Therapeutic Voice Processor, which he uses to guide two cores through couples therapy.

Anthony (and The Band)

“

Why don't we ever get anyone more intelligent, introspective. Someone like... me! I think it's because of you. Yeah, you're just driving them all away with all your sulking. — Interview Core to Anthony about the lack of good guests

”

Anthony and The Fritz Brothers Band is a trio of turrets, two of which are defective. Anthony often faces issues with his defectiveness, such as falling apart during a rimshot or having trouble with romantic interests.

This is hell, isn't it? It's android hell, isn't it? I knew it, I knew it was real! Click to listen — Paranoia Core

”

The Paranoia Core is a corrupted personality core who appears in the first episode of the series. She is suspicious of all things, and speaks like a stereotypical conspiracy theorist, saying that it knows of "secret walls [being built] in the dead of night in secret to house all the secret boxes that contain files of all the secret rooms where all the real secrets are being kept."

Some time after the first episode, the Paranoia Core is fitted to a new frame and, in effect, "becomes" the Party Escort Bot from Portal.

The Protocol Core

Protocol Core

“

I'm not defective, I'm special. Click to listen — Protocol Core

”

The Protocol Core is a corrupted personality core who appears in the second episode of the series. He is very knowledgeable about all Enrichment Center policies and was "hand"-picked by GLaDOS to enforce "all of her wonderful regulations." The Protocol Core is under the idea that it was created to be perfect, and as such, denies being corrupted despite being in placed into an Emergency Intelligence Incinerator prior to the episode.

After the interview, he is brought before the Mainframe and disappears into a shaft underneath it.

The Ambition Core

Ambition Core

“

You think the fact that I don't have hands is gonna keep me from flipping you the bird? Yeah! Check that out! I'm flipping you a whole damn ostrich! Click to listen — Ambition Core

”

The Ambition Core is a corrupted personality core who appears in the fourth episode of the series. He has a very ardent demeanor, which he displays to everyone, including the incinerator. He tried to take over the show until he realized Anthony's incompetence.

After the interview, he was attached to The Mainframe.

The Ego Core

“

It's not every day Aperture builds a core like me. Perfect! Inside and out. Click to listen — Ego Core

”

The Ego Core, or Onathan, is a corrupted personality core who appears in the fifth episode of the series. Before the events of The Underground, he worked with the Interview Core processing test subjects. He describes himself as more intelligent and superior to the other cores, but is all the while overly egotistical. After the interview, he was attached to the Mainframe.

The Friendship Cores

Friendship Cores

“

Me and dumbass here are "friendship cores". We were designed to simulate trust or something stupid like that. Click to listen — Yellow about Blue

”

The two friendship cores, Yellow and Blue are two cores who appear in the sixth episode of the series. The two cores were fused after both being smashed together by a crusher due to Blue's antics. After this, Blue was constantly berated by his partner due to his stupidity and resulted in a fight during the show. They were put through a couples therapy session by the Interview Core. Afterwards, they were separated while being taken by the claw.

The Mainframe

The Mainframe

“

Hm. I don't like him. — The Mainframe about the Protocol Core

”

The Mainframe is a somewhat enigmatic character in the series. After each interview, the cores are sent to him. Anything the Mainframe dislikes, from cores to sitcoms, go down a trapdoor controlled by him. The cores the Mainframe accepts are attached to him, in a manner not unlike GLaDOS and her coresand also his first sketches of GLaDOS.
