Yi Sun-shin
Famous Korean admiral mostly known destroying a shitload of japs and their ships. Taught the Japanese that cannons>boarding ships. Defeated a 300+ ship fleet with only 12 ships. Underrated by westerners who haven't heard of him and he is probably the greatest admiral in the world. Kicked ass and never lost a single battle.
Person 1: Dude, you are so good. You must be the reincarnation of Admiral Nelson.
Person 2: No, I am Yi Sun-Shin, master of strategy and bane of the nips!
