9Does Thanos need to eat or sleep?
Thanos can eat regular food and has been known to enjoy meals in the comics, but he doesn’t actually need to. As an Eternal, Thanos is able to nourish himself by synthesizing cosmic energy. He’s a busy guy who doesn’t always have time to stop off for soup and a
sandwich, so it helps that he’s able to absorb energy from space and metabolize it.
It’s unclear if he needs to sleep, but when he had a farm in the comics, he had a bed, so it seems as though he might sleep as well. Wiping out half of humanity and wielding the power of the Infinity Stones must be pretty tiring.
