— Fact Sphere • Portal 2

The Fact Sphere is a Personality Construct that appears in the single-player campaign of Portal 2. It is one of the three cores to be attached to Wheatley in order to initiate a core transfer.

The Fact Sphere blurts out a series of random facts, some true, some false, and some just downright illogical. It holds itself in a high view, complimenting itself ("The Fact Sphere is a good person, with many friends.") while dismissing the other personality cores. ("The Adventure Sphere is a blowhard and a coward.")
