How come Marcus didn't know that he was a terminator? Unlike humans terminators have infrared vision (along with numbers, calculations and stuff).

He should have known that he was a machine (or that there was something wrong with him) from the very moment he woke up.

  • because, that was his mission

  • No..He thought that was human all along. He was sad and triggered seeing the endo-skeleton underneath his skin which proves that he didn't knew that he was a terminator.

  • Because he was programmed that way

  • So he was programmed in such a way that the red vision and popping numbers were absolutely fine (even if he thought that he was human) but the metal endo underneath his skin was a major problem? Maybe skynet forgot to program that it is normal to have metal skeleton under your skin...LOL.

1 Answer 1


It was answered by the Serena A.I. (Skynet) herself:

Dr. Serena Kogan: Welcome home, Marcus. We knew you'd be back. After all, it was programmed in you. Oh, and you executed that programming beautifully.

Marcus Wright: What am I?

Dr. Serena Kogan: You are an infiltration prototype. The only one of your kind. Advanced Cyberdyne's work, we resurrected you, amended it.

Marcus Wright: You're dead.

Dr. Serena Kogan: Calculations confirm Serena Kogan is the

John Connor: easiest for you to process. We can [transforms into Kyle Reese]

Kyle Reese: be others if you like. Marcus, what else could you be... if not machine? [transforms back into Serena Kogan]

Marcus Wright: A man.

Dr. Serena Kogan: The human condition no longer applies to you. Accept what you already know. That you were made to serve a purpose. To achieve what no other machine has been able to do. To infiltrate, find a target and then bring that target home to us.

[flashback recording from Marcus' perspective]

John Connor: We've been at war since before either of us even existed. You tried to kill my mother, Sarah Connor.

Dr. Serena Kogan: In times of desperation, people will believe what they want to believe. And so, we gave them what they wanted to believe. A trick in the form of signal the Resistance thought would win the war. And they were right, it will end this war. Except that it is the Resistance that will be destroyed. Not, Skynet. Our best machines have failed time again to complete a mission. Something was missing. We had to think, radically. And so we made you. We created the perfect infiltration unit. You, Marcus. You did what Skynet has failed to do for so many years. You killed John Connor. Don't fight, Marcus. Remember what you are.

Marcus Wright: I know what I am.

[rips out computer chip, crumbles]

Marcus Wright: I'm better this way.

Dr. Serena Kogan: You will not be given a second chance. You cannot save John Connor.

Marcus Wright: Watch me. - IMDb

He was programmed that way to believe that he is human bu to also achieve his mission which he did. It was his will power that he reversed his mistake later.

  • If he was programmed to believe that he's human then what happened to that programming when he saw his endo-skeleton?? Sees with infrared vision = Everything is normal. Sees metal endo underneath = Starts shouting and crying.

  • @Elijah786s that's how his programming was done. It was done to achieve specific mission which he did.

    @Elijah786s The movie clearly tell us that he was programmed that way, reasoning how this is done, though, seems to be beyond what the film actually explains and a futile endeavour, we're not doing speculative science here. I wonder, though, why you even think he sees stuff in infrared at all. He might simply have his normal human eyes and a normal human brain with a mechanically enhanbced body. He onces was an actual human afterall.

  • Dr. Serena Kogan plays recordings from marcus (of his previous conversations with john) and those were in infrared.
