Judging from his rank, Chief R was most likely an established member of the government sent by the Federation to Giga City, perhaps something like a viceroy or assistant to thereof. Chief R possesses a very calm, reserved personality, but is also decisive and prudent, evident when he instructs X to rescue Nana and the captives of Tianna Camp as first order of business after control over Central Tower is re-established. He also appears to be a strategist and due to his lifetime career at Giga City, he is very knowledgeable of the surrounding areas of the island and its residents.
However, tragically, Chief R was killed in an ambush set up by Colonel Redips. As he was signaling a military airship (which was sent by Redips under the pretense of transporting the Maverick Hunters back to base) to land, the aircraft instead opens its underbelly to reveal cannons instead of landing gear and fires on him.
- The parrot on his shoulder is a monitoring and information handling Mechaniloid, and Chief R seemingly goes nowhere without it. The parrot was shown to have survived after Chief R's death, sitting in the ruined portions of Giga City.
- Chief R shares the same voice actor with Ninetails and the rest of his clan in the Japanese version.
