King Hassan is the First Hassan from Fate Grand Order, the mobile game in the Fate series, presented as the legendary founder of the Hashshashin and the Old Man of the Mountain. His deep, solemn voice lines are widely clipped by fans for edits and soundboards, with numbered variants like Dokoda 3 helping users tell short lines apart. The clip stays in use because the delivery sounds imposing out of context, making it useful for dramatic jokes, character entrances and reaction posts in anime and gaming communities online today.
