T-1000

Is it a robot

Body T-1000 is made of liquid metal mimetic polyalloy rendering it capable of rapid shapeshifting, near-perfect mimicry and rapid recovery from damage. including fitting through narrow openings, morphing its arms into solid metal tools or bladed weapons, walking through prison bars, flattening itself and imitating the pattern and texture of the ground to hide or ambush targets.

it creates a motorcycle helmet and sunglasses when these items were necessary for its disguise

The T-1000 can also change its surface color and texture to convincingly simulate flesh, clothing, and other nonmetallic materials. It is capable of accurately mimicking voices as well, including the ability to extrapolate a relatively small voice sample to generate a wider array of words or inflections as required. However, its morphing abilities are limited by complexity, mass, and volume: it cannot transform into complex machines with mechanical moving parts or chemical fuels (like guns or bombs), limiting it to stabbing weapons unless it acquires external hardware, and its volume prevents it from taking the form of a small object like a pack of cigarettes, although it is capable of impersonating larger people (Most likely by simply making its interior somewhat hollow rather than remaining a solid mass).

Like all Terminators, the T-1000 possesses superhuman strength. While relatively equal in strength to the T-800, thanks to its morphing abilities and immunity to mechanical damage, it is shown to be capable of overpowering the T-800 in hand-to-hand combat, despite its more slender frame and lack of mass compared to its predecessor. It can also run fast enough to catch up to a police car accelerating away from it, although at times it can acquire and drive vehicles if it requires increased speed. Since the slender, smaller frame is its default appearance, when assuming a person that is physically taller and bulkier than it, the T-1000's density decreases and becomes slightly hollow, also causing it to lose the center of gravity, forcing it to take harder steps and slower pace to make an appearance of a bulkier person.

The T-1000 is effectively impervious to physical injury and any damage to its body will only momentarily stagger it for as long as it takes to repair any wound or deformation. Bullet wounds are a minor inconvenience; the T-1000 can shrug off and repair injuries from small arms fire but a high-kinetic impacts from shotgun blasts or a large explosion will knock it out for a few moments before it can recover. If a part of its body is detached, it will liquify and flow back into the T-1000's body, with its detached nano parts being able to track the core of the body from a far range, up to 9 miles(14.5 km) It is explained in the prologue to the novel adaptation of the film, that the T-1000 is able to completely reform and reshape itself at will, due to its "cells" having been programmed by Skynet with on-board nanotechnology. This technology can be programmed with commands from Skynet, and can help the T-1000 scan the cellular makeup of whatever it is touching (including the DNA of living animals), and can magnetically attract broken off pieces of itself back to the main body.
