Which of these film characters says, "Hasta la vista, baby"?

"Hasta la vista, baby" is a catchphrase associated with Arnold Schwarzenegger's titular character from the 1991 science fiction action film Terminator 2: Judgment Day. The term "Hasta la vista," literally "Until the view," is a Spanish farewell that can generally be understood as meaning "Until the (next) time we see each other," "See you later," or "Goodbye." The phrase is once again uttered in the 2003 film Terminator 3: Rise of the Machines by John Connor.
