Information on the Rapper
Thor is the Norse god of Thunder. He is the son of Odin, and brother to Loki. In Norse Mythology, he is portrayed as a powerful, relentless and quick to anger tyrant. However, in his alternate depiction, shown in Marvel Comics, Thor needed to be taught humility so Odin turned him into a mortal named Donald Blake, losing his memories and powers. He adapted to his new world and lived in peace until the alien species, Kronan, invaded, causing him to hide in a cave. He found himself trapped due to a boulder in the way, and used a walking stick to get out. This stick was revealed to be Thor's hammer, Mjolnir, which turned him back into the god. In the Marvel Cinematic Universe, he is shown as a clueless alien dropped into Earth's society, with little idea as to how the human world works.

He frequently stands alongside the Avengers in the defense of the people of Midgard (Earth), often against the schemes of his adopted brother Loki. He formerly dwelt in a recreation of Asgard in Oklahoma.
