I need help.

[Frisk E. Coyote]

The "ninja" aspect of the android comes with its ability to become completely un-detectable through a series of stealth based technology, like emitting a sound that's so high pitched, human and even bat ears can't hear it, at a frequency that attacks the brain through the ear-drums, shutting down all five basic senses and other senses that may be around. It can also shut down and scramble radars, tracking devices, remote signals, communication devices, etc with a built in, top-of-the-line scrambling device. It also moves insanely fast, has insane reflexes and strength, and can produce numerous blades of varying shapes and sizes, from a special nano-tech fiber its coated with, similar to living metal. Its made of nanites that are half the size of a molecule, and so they can easily alter the chemical compounds and properties of its armor, like making it indestructible, light-weight, fire-proof, water-proof, magnet-resistant, EMP resistant, you get the drift. It also has a VERY intricate knowledge of anatomies, allowing it to make fast, precise, and accurate attacks that target all the critical areas and weaknesses of a target, allowing for instant kills. It can also adapt to fighting styles and tactics, so if it makes a mistake, which is rare, it won't happen again, making it unbeatable in hand-to-hand and tactical combat. It is also equipped with optical sensors that can detect heat, the sound of blood rushing through veins and heartbeats, see clearly in pitch darkness, see clearly in blinding flashes of light, and a optical ability that allows it to sense living things, making it nearly impossible to get away unless one was dead. Even then, it'd find the body with its' enhanced artificial olfactory senses, which can hunt down a scent from across the globe. Its sound sensors are also very well developed, making it nearly impossible to get the drop on it. Its speed far exceeds Mach 5, and it can move so fast as to vanish and reappear several kilometers away in a single step. Its nano-tech fiber plating is streamlined and designed to cut down friction, so instead of breaking the sound barrier, it bypasses it, making it silent. It can switch that function off and repeatedly attack something with sonic booms.

The "cowboy" aspect merely means it has a top-of-the-line multi-targeting and multi-lock-on system, allowing it to kill things with a headshot from a maximum of ten miles away by calculating the movement of the earth, wind speed, and movement of the target. Likewise, it can fire a bullet that can ricochet off obstacles several times until it hits it's target. It can produce innumerable firearms like it does with blades, from fifty caliber machine guns, vulcan cannons, mini guns, gattling guns, shotguns, all loaded with special bullets it generates within itself with its nanites, which merely need to take in matter, like carbon, or lime, or what ever, to compress into high caliber slugs or canon shells. After all, even bullet proof vests aren't that bullet proof. Its specialty is lasers, which can be intense and manipulable enough to make a crisscross net that can slice cleanly through anything, or fire a straight beam of pure destruction to level an entire city, or it can be soft enough to make a laser-lasso to catch people and not harm them. It also has advanced hologram technology to make it look like anything it wants.

The "weapon of mass destruction" aspect of the android is that... a weapon of mass destruction. It uses intense lasers, missiles, bombs and nanites. Its body can release floating spheres the size of large marbles that dart around so fast its nearly impossible to see them with the naked eye, and they fire high intensity guided lasers, or explode with the strength of C4 bombs if they want to. It can shoot a multitude of missiles, again, created by the nanites, powered slightly by the android's nuclear-powered core each, making for a highly destructive weapon. Lastly, its nanites are self-reproducing, so they heal/repair what ever damage is done to it. The android can also unleash these nanites in a silvery storm that disintegrates all it comes in contact with down to the molecular level turning the matter they consume into more nanites, not unlike the ones in "The Day the World Stood Still". Its body can release bigger spheres that shoot out into orbit, and can fire down super lasers with surprisingly high accuracy and precision from space. They can also come together and form a huge orb that unleashes a powerful orbital bombardment laser like the ones shot from spaceships in "Independence Day". Finally, if its' ever defeated without any chance of repair or success, which is nearly impossible because even if it managed to get damaged, the nanites can rebuild it nearly from scratch, it would detonate itself like a nuclear bomb.

No one has any idea WHO built the android or who programmed it (that's up to you). But it's called SLAYER.

Is that suitable for Mr. Cruel's standards? Tone it down or up as you see fit. X3
