During the missions, whatever movie you prefer, Tony Stark spend more than 5 hours per mission (given the time passed and the sequence of the movies) in the suit. I was wondering if he has physiologic needs (such as poop or pee) and having the armor, what could he do?

    "Urinate": sophisticated, adult, medical term for liquid elimination. "Poop": Four-year-old's term for solid elimination. I would expect either "Urinate or defecate" or "Pee or poop" but the mixture amuses me (+1 anyway). Mar 13, 2016 at 5:39

Yes, he can. Specifically, he can urinate.

In the second part of Iron Man (2010), Tony is celebrating his birthday with almost 90% of paladium in his body and decided to celebrate like the last party of his life and put his suit for the party. When he's making a speech in front of his guests, he says that many people ask often how to go to the bathroom with the armor and make a joke.

Screenshot of the movie. Suddendly, Pepper ask Tony to end the party, Tony try to kiss her and she said:

You just pee in your suit!

Tony replied Pepper:

I know but it has (the suit) a filter system. You could drink that water (ex-urine).

    This answer feels incomplete given that we often see him going in or out of his suit but never naked or with what can see as filtering clothes. Mar 11, 2016 at 9:36

    Clearly he's wearing underwear with suitable (all puns intended) attachments

    @olivier that's an intentionally ignored plot hole for the sake of a joke.

    Next question: how could Pepper tell he just pee in the suit? ;) Jul 4, 2021 at 9:12
