Zeta R-02's biggest drawback is her speed, as she is the slowest moving playable character. Her bladed dash attack also executes very quickly, making it useful for escaping a tight situation. She is capable of devastating many common enemies with only one or two combinations, and can withstand more enemy grapple attacks than any other character. As one might expect from an artificial life form, Zeta R-02 is exceptionally strong and durable, having the highest health and physical attack power in the game.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. When Neoeclipse knew Vannessa (known at that time as the nickname of Amy Rose) and became friends Zeta was gifted to her being then the new owner of Zeta and being know as Zeta R-02 since then she use hers as a persona online. Later was a new mascot of MetroVG instead of Chip-chan. Zeta R-02 (ゼータR-02) (Zēta R - 02) was created by Neoeclipse being part of his fan fic Called 'Project R'.
