tyrannical, powerful

豪 is composed of a variant of 高(tall) and 豕(pig). 高 here conveys the idea of long and pointed, referring to long, stiff, bristly animal hair, while 豕 is the pictograph of a pig; thus 豪 originally meant a creature with spiny, bristle-like hair and pig-like appearance (referring to the porcupine or a similar bristly beast). This creature has a fierce and intimidating appearance, so 豪 extended to mean powerful, grand, or domineering.
