Chief R

Chief R is the leader of the Resistance Movement on Gigantis Island. Chief R was held captive by Wild Jango in Central Tower when X first arrived in Giga City. After he was freed, he resumed command of Central Tower and instructed X personally on the fight against the Rebellion Forces. Judging from his rank, Chief R was most likely an established member of the government sent by the Federation to Gigantis Island, 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 is very knowledgeable of the surroundings of the island. Due to the lifetime career at Giga City, Chief R is very familiar with the location and its residents.

Tragically, however, he was killed by an ambush set up by Colonel Redips (he was signaling the whale military plane to land, but then the plane revealed cannons instead of landing gear and blasted holes through him.).
