Wolf is a combat robot created by Dr. Polto, serving on a team tasked with protecting Earth from invasion and safeguarding Robin, Dr. Polto's son. His core functions encompass espionage, intelligence gathering, and offensive combat. He operates with super-speed and possesses super-accurate aiming abilities that surpass any machine's precision. His design enables transformation into human-like forms or objects such as trees and furniture, facilitating undercover operations and enemy imitation.

Characterized as nihilistic and built without emotional channels, Wolf nevertheless exhibits expressions of joy, anger, sadness, and happiness, especially when Robin is endangered, triggering an immediate shift into combat mode. Visually, he adheres to a "rule of cool" aesthetic, frequently depicted wearing sunglasses and dual-wielding guns.

He executes sabotage and infiltration missions, utilizing his transformation abilities for tactical advantage. Occasional overconfidence during operations can lead to compromised situations. Beyond combat, Wolf acts as a tactician, a role positioning him as a potential third-in-command within the team hierarchy due to his strategic contributions.

Wolf appears in the *Cyborg 009: Monster Wars* film, where the Rainbow Sentai team encounters the Cyborg 00 Cyborgs during a mission involving a sea monster.
