How does masterchief go to the bathroom?

Answer 1

We've never seen the inside of his armor. He might, for all we know, have a toaster in there if not a toilet. Just think of him as "Master Chief" THE ASTRONAUT !! no u noob he r guy who has toilet in his hat

Answer 2

Yes in fact he can. The suit has a recycling system so when you pee. it is stored and the contaminants are removed to make drinkable water. this water is stored in pouches on the inside of the thighs.
