The Adventure Sphere, also known as Rick, is a corrupted personality core of male programming who appears in the single-player campaign of Portal 2.
The Adventure Sphere speaks in the manner of a stereotypical "tough guy", spending most of his time boasting about his bravery and lust for danger. Upon seeing Chell, he flirts with her and makes increasingly chauvinistic comments. He even tries (but to no avail) to convince Chell to take a "lady break" while he deals with Wheatley by himself.
- In Portal 2, he was voiced by Nolan North who reprises his role in the game.
