Her animations and dialog all seem to indicate that she's able to retain logical thought, though if she's not selected as a playable character, she's shown in the opening scene to be just as susceptible as the rest of the team. Zeta R-02 seems to have the least trouble with the cloud's effects, likely due to her artificial nature.
Zeta R-02 is a gynoid (the term for a female android), and her robotic nature is evident by numerous visible articulation seams on her body, as well as her ability to produce powerful electrical blasts or extend blades from her wrists. On her head is a gold-colored headset capable of producing an antenna, visor, and other useful gadgets. Their hands, along with the trim on her suit and boots, is gold in color. Zeta R-02 appears as a white female echidna dressed in a form-fitting red and black bodysuit which flares at the ankles and wrists, and black boots.
