The upgraded form of Wahoo.
Visual changes include Japanese flag kill markings on the part of Wahoo's white scarf wrapped around her neck, and the words "Shoot the Sunza Bitches" on the part of the scarf trailing away from her. A full-sized Oerlikon 20mm Gun is also added to Wahoo's arsenal, with a red-colored gun sling holding it over Wahoo's shoulder, separate from her other rigging.
