Built for US Agent, the Black Mariah could hold up to four passengers. While it was primarily used in the air it could also function underwater. Smaller transports such as jet-skis could also be placed on board. Defensively it could project a forcefield and cloak. The upgraded version (or a variant) carried missiles and had two detachable vehicles: the nose section could fly on its own, and the cockpit could become a skimmer.
