Jose Barrera was a destined Resistance fighter in the future. He would later go on to serve as a lieutenant under John Connor in the War against the Machines. This changed when a T-X sent back in time killed him at the fast food restaurant where he worked.
It was likely that he and the other seven people on the T-X's hit list contributed greatly to the Resistance's victory as Skynet sent it back through time to have them eliminated since John Connor was living off the grid at the time and could not be located.
- In Terminator 3: Rise of the Machines video game, Barrera's name is George Barrera.
