The Interview Core is a corrupted personality core that 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. He is lacking of any limbs since he's a core.
