Thor

Thor is an As. He is the god of thunder in various Germanic mythologies, most notably Norse mythology. He lives with his wife, Sif, and their two children, in the dwelling of Bilskirnir in Asgard. Thor is the son of Odin, king of the Aesir, and the goddess Frigg. Thor wields the magic hammer Mjolnir, with which he can produce lightning and thunder, smash his foes and hurl at enemies, after which it always returns to his hand. Thor is the mightiest warrior of the Aesir.

Mythological background
While Frigg is shown to be the mother of Thor in the Valhalla comics, in the mythological accounts he is stated to be the son of Odin and the goddeess Jörd (Old Norse: Jörð or Jǫrð), a personification of the earth, sometimes called Fjörgyn instead, although in some sources these two names are used for two separate goddesses. In the comics, Frigg is a composite character of Frigg and Jörd.
