Metal Gear RAY (manned)

Metal Gear RAY was an amphibious Metal Gear design created by the U.S. Marine Corps after the Shadow Moses Incident, and later stolen by the Patriots.

Background
Metal Gear RAY was originally developed as a counter measure to the abundance of Metal Gear REX derivatives being built around the world because Ocelot released REX prototype's exercise data in the black market after the Shadow Moses Incident in 2005. This makes RAY the first Metal Gear not to be specifically designed to launch nuclear missiles. However, it was also believed to have been created as a result of an intense rivalry between the Marine Corps and the Army, especially after the latter's part in developing REX. RAY was commissioned by the Pentagon and the U.S. Marine Corps, and Commandant General Scott Dolph helped spearhead the project. It was a standalone Marine Corps project that was able to operate independently, without requiring any Naval assisstance.

In 2007, the Marines attempted to transport the Metal Gear RAY prototype, aboard the U.S.S. Discovery, to a testing location more than 500 miles south of the Bermudas, outside of the U.S. Second Fleet's operational range. However, Philanthropy had learned of the scheduled testing of the new Metal Gear unit, and Solid Snake was dispatched to infiltrate the disguised tanker, in an attempt to leak pictures of RAY onto the Internet and expose it to the world. However, Solid Snake was beaten there by Revolver Ocelot, Sergei Gurlukovich, and the Gurlukovich Mercenaries. Ocelot then proceeded to steal RAY (or, as he put it, "taking it back"), kill Gurlukovich and Dolph, then blew up the tanker, taking the Marines and the mercenaries along with it. Just when Snake arrives and points to Ocelot (whose about to enter RAY) at gunpoint, Liquid Snake's spirit takes over Ocelot's body and pilots the Marines' prototype, killing the suriving Marines in the tanker. Snake was also supposedly killed in the blast, as well as framed for causing an environmental disaster. Afterwards, the Patriots had RAY redesigned and mass-produced in order to protect Arsenal Gear, a new type of Metal Gear that the U.S. Navy were constructing.

In 2009, Ocelot gave the original RAY prototype to Solidus Snake, which was used during the takeover of the Big Shell offshore cleanup facility, the disguise of Arsenal Gear. After special forces agent Raiden shot down Solidus's Harrier II, RAY emerged from the waters to catch the fallen aircraft and launched cluster bombs that devastated the surrounding area. After Solidus ordered the Harrier's pilot (Vamp) to flee, RAY took the jet and Solidus beneath the waves. After witnessing RAY's appearance, Raiden believed it to be the new Metal Gear that was in development and, thus, was alarmed that it had already been activated.

After the GW AI became corrupted by Emma Emmerich's worm cluster, Ocelot (after revealing that he was a Patriot agent) attempted to use the prototype RAY to execute Solid Snake, Raiden, and Solidus Snake. First, Ocelot used the gatling gun pods against Solidus, who used his exoskeletion's power to counter. Then, Ocelot used RAY's payload of missiles on the group but Dead Cell leader Fortune was able to shield them all from the attack using her "luck" powers. Just when Ocelot prepared to use RAY's water cutter against the group, "Liquid" suddenly took control of his body and then jumped from Arsenal within RAY followed by Snake, with Arsenal Gear about to crash into Manhattan. Snake, although unable to stay with RAY, had nonetheless managed to plant a transmitter on RAY so he could track Ocelot's movements.

In 2014, Liquid Ocelot a mass produced Outer Haven model of Metal Gear RAY in battle against the original Metal Gear REX (piloted by Old Snake) on Shadow Moses Island. The model had undergone further modifications, displaying traits such as the new grey body and an enhacned leap ability, while retaining the pilot's cockpit and dual eye sensors as all models have. However, despite being designed as an anti-Metal Gear weapon, REX's sheer strength was able to effectively counteract RAY's superior agility and defeat it.

Information
Designed as an amphibious weapon to meet the standards of the U.S. Marine Corps, Metal Gear RAY was a versatile weapon both on the ground and underwater. Standing over twenty meters tall, the original prototype RAY required a pilot to operate it, after having first undergone VR training. The cockpit controls also acted as a harness of sorts, pressuring the pilot into the seat, to avoid being thrown around. The giant "wings" located on each side of the unit acted as a propulsion device. A tail on the hind end of the unit helped to steer the unit underwater.

RAY's initial and most prominent armament was a water cutter housed in the mouth as sort of a replacement of REX's Rail Gun, although its power exceeds that of a normal water cutter. Powered by a massive pump, water would be sucked into an internal tank and then expelled as a narrow stream under extremely high pressure, approaching astronomical speeds. As RAY's primary weapon, its purpose was to sever and slice almost anything that stood in its way, even dense armor, such as that of Metal Gear REX.

Other armaments include gatling gun pods located at the end of each "wing," a missile pod located on its back capable of firing homing missiles, and knee-mounted missile pods for ground defense. Metal Gear RAY's exterior metallic casing and armor is made of a ceramic-titanium alloy for defense against light to medium projectile assault.

Metal Gear RAY had a more organic design than previous models, both in appearance and in function. Its streamlined shape helped to deflect enemy fire and allowed for greater maneuverability both on land and in water. Its interior workings were also somewhat organic, as it had artificial fibers that contracted when electricity was applied, much like natural muscle, instead of typical hydraulics; this pseudo-muscle tissue made it very maneuverable. It also had a nervous-system-like network of conductive nanotubes, which connected the widely dispersed sensor systems and relay commands from the cockpit to the various parts of RAY's body, automatically bypassing damaged systems and rerouting to auxiliary systems when needed. Another feature was its blood-like armor-repair nanopaste, which was secreted from valves and coagulates wherever the exterior surface was damaged. Particularly unusual was its "face," with two "eyes" and a gaping "mouth," only seen when the head armor was opened.

Trivia

 * RAY was named after the manta ray due to its aquatic nature. In 2009, the Patriots informed Raiden that the name "Ray" was also one of the Allied codenames for the Japanese Mitsubishi A6M2 Zero fighter aircraft used in World War II.
 * During Scott Dolph's speech, Dolph mentioned that RAY's final form was to be unmanned, indicating that the Marine Corps. planned to make the mass production models unmanned before the prototype was stolen by the Patriots.

Behind the scenes
In the original game plan of Metal Gear Solid 2, Sergei Gulukovich was killed when Ocelot had RAY stomp on the former Spetsnaz colonel (similar to the scene in Metal Gear Solid when Gray Fox was killed by Liquid Snake via Metal Gear REX).

In an R1 scene for Metal Gear Solid 3, a model for RAY could be witnessed in Granin's office, along with REX and Jehuty. In addition, according to the Director's Commentary, the Metal Gear D-like design for Granin's blueprints for Metal Gear were actually intended to be that of Metal Gear RAY.

In the Metal Gear Solid: Peace Walker Official Art Works book, there was originally supposed to be a monster called M/G Ray in addition to Gear REX that directly resembled its namesake, Metal Gear RAY.

Metal Gear Solid 3: Snake Eater
RAY makes a cameo appearance as a model (alongside REX's model) displayed in Aleksandr Leonovitch Granin's office during Operation Snake Eater.

Super Smash Bros. Brawl
RAY makes several cameo appearances in Super Smash Bros. Brawl: in the background of the Shadow Moses stage, as a collectible sticker, and as a trophy with this description:

"An amphibious Metal Gear developed by the U.S. Marines. Revisions to the prototype enabled mass production and made it a viable battle weapon with massive firepower and remote operation. Wings and a tail make it look monsterlike, but scarier still is the high-pressure water cannon in its mouth that fires a stream of water that can slice through rock."

Scott Dolph also pionts out that it would have been used in conflict (pretty much replacing tanks.
