Terminator 2: Judgment Day
Meanwhile, the Terminator and the unknown man both find John Connor in a shopping mall. Then, there is a twist: the unknown man is not the one who is meant to stop John getting killed, as the people watching thought so based on the first movie. The Terminator from the first movie is now the one meant to stop John getting killed, and the other man is another Terminator trying to kill John. When the good Terminator rescues John, he tells him what is happening. He is a Model 101, made by the future John Connor to act as the one to keep him from harm. The other Terminator is a T-1000, sent to kill him. It is made of mimetic polyalloy, or liquid metal, making it able to morph anyone or anything he touches of equal size, except "complex machines" like "guns and explosives" because they "have chemicals, moving parts." It can however form "knives and stabbing weapons."
