P-body



P-body (referred to as Orange by GLaDOS), is Atlas' tall and wiry partner in testing, and is one of the two playable android Test Subjects built by GLaDOS for the Cooperative Testing Initiative in Portal 2, which was devised to phase out human testing.

Gameplay-wise, P-body is played by the guest of the Co-op session; the player that receives an invitation.

Biography
P-body is an orange eyed Core with a design similar to that of a Turret, and is portrayed to have somewhat less masculinity than in Atlas - if not a hint femininity. Along with Atlas, the two bots are pitted against a series of tests built by GLaDOS herself, utilizing the many different mechanics previously encountered by Chell from the game's single-player campaign.

Development and Acting
Both P-body and Atlas are voiced by Dee Bradley Baker.
