Kryptonians according to Byrne:
In his run on Superman, John Byrne established that Clark burns 100% of everything he eats for energy.
Complete metabolizing means no waste.
No waste means no pee or poop.
No pee or poop means this conversation is less than pointless.
Hmm. During his FF run, Byrne had Reed invent a waste-free super-food to explain why the FF never needed to poop during, say, extended jaunts through the Negative Zone.
Does Byrne dislike the idea of superheroes pooping, or did he just not want to add toilet facilities to the Fantasti-Car?
