Terminator 3
In The Terminator 3 Judgment Day John Connor, along with the Terminator are on the run from a new type of Terminator called the T-X, which is a terminator designed to hunt and kill rogue terminators. Obviously this terminator needs to be faster and stronger than any of the previous ones, the pure solid t-800, and the liquid - like t-1000. So how do you create a machine that’s better than both of them, while still a machine, well, you turn it into a gaseous form… just kidding, you combine their strongest aspects, while taking away their weaknesses. The T-X is a solid machine, with a liquid overlay, essentially combining both of the terminators form the last two movies. For proof of this, you just need to look carefully in the movie, to be specific the scene where the T-X copies the form of Kate’s fiance, when she turns back it’s liquidy, like the t-1000, but in some scenes she has a physical form, like in the end scene where she dies.
