Modi is the son of Thor, the most powerful of the Norse gods. Though he inherits his father’s brute strength; he is also known for his fearlessness. Boundless courage emboldens his physical strength all the more.
Modi’s courage sends him into a blind fury while at war. Because of this, he is often associated with the Norse warriors known as berserkers. These soldiers, like Modi, fight as if in a wrathful trance with little care for their own lives. The phrase “going berserk” dates back to the blind bravery exhibited by Modi.
