Alien Weapon Unit

Background
When the alien ship crashed on Earth, they accidentally killed two humans on the site and they are forced to restore them. Due to a short time they had, they have to make do with any replacement they had on board, which is a weapon-grade robot thus giving birth to the new Inuyashiki Ichiro and Shishigami Hiro.

Origin & Capability
Not much is known about the origin of the alien or their weapon but the robot unit is powerful enough to destroy the Earth (Proved by one of the aliens in the UFO mentioning that giving them the replacement body could destroy the planet). The robot unit is capable of:

Immortality and Immunity The units require no maintenance on behalf of the human operators and is resilient enough to withstand conventional firearms and military-grade firearms. However, if they take sufficient damage they will fall unconscious and the center of their processing unit will assume control of the body and eliminate any remaining hostile encounter present in the vicinity of the unit. The unit is immune from human disease

Flight The robot is capable of flight using a fold-out jetpack with two thrusters from the back. The altitude and the duration of flight is indefinite (As Ichiro could take a flight until he's outside the atmosphere of Earth).

Inhuman Strength The strength of the unit is inhuman enough to be able to lift planes simultaneously without straining the host. Also capable of ripping out a meteorite with ease

Direct Tech Interface The unit also able to interfere with any technology equipment. This includes accessing satellite links, cameras both CCTV and personal, social media sites, government databases. It is capable of remotely manipulating banking systems, automobiles and seemingly all electronically connected screens. It is possible to extend the user's other powers through an electronic medium (demonstrated by Hiro killing fifty 2channeler commenters through their mobiles and computers) It can locate a person provided they are in vicinity of a technology equipment such as phone or computer. Other electronic devices like cellphones can be integrated into the body's system including existing cellphones (functional USB ports can be replicated on the body). One unit cannot interfere with another unit's functions.

Healing The unit is also capable of curing all kind of wounds and disease to living beings (including animals). It is capable of resurrecting a recently deceased person. It is unknown if the unit can reverse the effects of aging.

Enhanced Sight and Hearing The unit is capable of hearing all sounds within a large range (this is limited by the owner's audio processing capacities) and see clearly within a radius of 100 km.

Simulation The processing unit could run a simulation to determine an outcome of an event Overcharge  Although it as only occurred in the Live Action Film and only used by Inuyashiki Ichiro, the weapon unit may also be capable of instantly repairing itself from major damage & powering up its systems and overcharging the supercomputer to increase its strength, reinforcement of the weapon unit and increase its flight boost for a short period of time. In the final battle in the Live Action Film, during in a final slow-motion clash, Shishigami Hiro's right robotic arm was destroyed when he punched Ichiro in the face due to his reinforcement increase and Ichiro penetrating and destroying part of Hiro's chest due to his increased strength and speed.

Built-in Weapons There are four kinds of weapons in the unit shown so far:
 * Multi Laser Ray (Also known as Multi Rockets in the Live Action Film)  Usually activated when in unconscious mode. Can be used as a non-lethal method of crippling an opponent or used as an explosive guided laser ray. Can be activated outside the unconscious mode (autopilot) through the means of exposing the weapon hidden beneath the robot's body. In the Live Action Film, the Multi Laser Ray is replaced with mini multi rockets, which the host can also control the directions of the rockets through the host's super computer. These rockets can cause an explosive impact, and requires a few seconds to reload before firing them again.
 * Invisible Laser Weapon Like a laser ray but doesn't make any sound or leave any trace of light or gunpowder. Can be activated without exposing the interior part of the robot. Can be used like a regular handgun or a full-automatic rifle. The laser is also able to travel through multiple screens to shoot from a safe distance (Shown as Shishigami Hiro killed many civilians through smartphones and large screens across the city). As long as he is facing someone, whether or not he can see them, it will effect them as though he shot them personally. It also functions as a cutting beam, which he used to cut the palm of the Third Victim before shooting her dead.


 *  Arm Cannon  A large, long cannon located inside of both of the host's arms. When activated, both of the arm cannons are exposed from both arms. The arm cannons can do a massive amount of damage, create small craters around the area and can even vaporize strong materials such as metal. The arm cannons require a few seconds to charge up before it's ready to fire. The host can activate the arm cannons at anytime they want to use them.


 * Self-Destruct Mechanism  As the name implies, it capable of self-destructing itself, destroying the host and produces an explosion bigger than a nuclear missile and also creates a blinding light that could be seen from thousands of miles away. Activation sequence requires the host to push both of their eyes inward and takes a few seconds to go off.

Weaknesses
The units require copious amounts of water to function. It is is possible that they run on hydrogen fuel, produced through the electrolysis of water into its hydrogen and oxygen components. Hydrogen fuel is used in space exploration, and one of the world's largest production facilities is located in Japan. The bodies are incapable of digesting food.

While they are invulnerable to most human weapons, they can be damaged by another unit. As mentioned before, the operator may fall unconscious after a traumatic blow, but the unit's automatic system will take over.

Hiro revealed that he had no strong feeling of being a human attached to their consciousness. Inuyashiki Ichiro, however, did not have the same reaction.

Relationship with human operator
The unit is highly intuitive to the user


 * Hiro's signature attack is to use finger guns that mimic the effect of a real gun. The hand gesture and sound effects he makes are most likely decorative, and the AI is able to interpret and recreate Hiro's desired effect
 * When Inuyashiki Ichiro faced teenage criminals, the automatic system fired warning shots. Later at a yakuza clan's headquarters, the system dealt paralysing and blinding injuries, but left everyone alive. It is highly unlikely that Inuyashiki planned these attacks beforehand. Therefore, the AI must have read Inuyashiki's subconscious attitudes and predicted what kind of strike would be most suitable. When Hiro falls unconscious during his attack on a police building, his unit fired lethal blows. This is likely because of how the AI interpreted Hiro's motivations.

The human's will is fully and completely transplanted into the unit through unknown methods. The units appear to make no conscious or subconscious attempt to influence the user. The alien species that made the units do not appear to control the users through the machine.

While the unit has many features, it is left for the user to discover them on their own. The ease with which the user can use each feature may depend on the user's personality (Hiro easily discovers attack capabilities while Inuyashiki struggles).
