Thor is a god in Norse mythology. He is the son of Odin, the chief of the gods, and Jord, the earth goddess. Thor is known as a protector of Asgard and Midgard, two realms in Norse mythology. He wields Mjölnir, his magical hammer that can create lightning bolts and thunderstorms. As one of the most powerful gods in Norse mythology, Thor has been venerated by many cultures throughout history for his strength and courage. Despite being a god himself, he is sometimes referred to as a demigod due to his human-like qualities such as having an appetite for food or drink and feeling pain when wounded.
