P-body



P-body, Atlas' tall and wiry partner in testing, is one of the two bots GLaDOS built for the Cooperative Testing Initiative in Portal 2, which was devised to phase out human testing. P-body has an orange eye, but his eye was red in early designs. GLaDOS created the testing initiative after. Along with Atlas, the two bots are pitted against a series of tests built by GLaDOS herself, utilizing the many different aspects encountered by Chell in single-player.

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