But more seriously Henri IV would be the closest to an Isekai character, after all he had "le triple talent de boire de se battre et d'être un vert galant" the triple talent of drinking, fighting and being galant with women. He was a fearless commander who told his men to rally to the white feathers of his helmet that would always be in the middle of the battle and a good king who worked a lot to bring peace between Catholics and protestants and to ensure that every peasant will have "a chicken in his bowl" at Sundays. Let us not forget that he survived to the Saint Barthélémy's night and changed 5 times of religion that would give him the perfect amount of dumb luck and perfect minmaxing of a good Isekai character.
