How do you pronounce Thanos?
As MissDanvers and Gabri said, Thanos comes from Thanatos, the embodiment of Death in Greek Mythology, therefore the correct pronounciation should be T-Ah-nos (I didn’t forget the H after the T, it’s just that your Th sounds different from the Greek θ, Theta).
What does Thanos always say?
“I finally rest. And watch the sun rise on a grateful universe. The hardest choices require the strongest wills.” “I think you’ll find our will equal to yours.”
