A demigod is a part-human and part-divine offspring of a deity and a human, or a human or non-human creature that is accorded divine status after death, or someone who has attained the "divine spark". An immortal demigod often has tutelary status and a religious cult following, while a mortal demigod is one who has fallen or died, but is popular as a legendary hero in various polytheistic religions. Figuratively, it is used to describe a person whose talents or abilities are so superlative that they appear to approach being divine.

A hero is a real person or a main fictional character who, in the face of danger, combats adversity through feats of ingenuity, courage, or strength. The original hero type of classical epics did such things for the sake of glory and honor. Post-classical and modern heroes, on the other hand, perform great deeds or selfless acts for the common good instead of the classical goal of wealth, pride, and fame. The antonym of hero is villain. Other terms associated with the concept of hero may include good guy or white hat.
