Thor

Thor was a deity in Norse mythology. His father was Odin.

Biography
The Third Doctor and Jo Grant met Thor in 141. He was actually a human son of Odin, High King of all Sweden; Odin was believed to be a god due to the power of Gungnir or Spear of Destiny, an alien artefact he possessed.

, under the alias of Frey, influenced the Vanir, a tribe of Vikings in 141 to fight Odin and Thor and the Third Doctor so that he could get Gungnir. The Doctor explained to Jo at the time that Norse mythology probably came from real adventures of early Viking history, as here the fight between Vanir and Odin's folk. (PROSE: The Spear of Destiny)

Thor once attended Bonjaxx's birthday party at Maruthea. (COMIC: The Incomplete Death's Head) Grant, a fan of superhero comic books, had a poster of Thor in his childhood bedroom. (TV: The Return of Doctor Mysterio)

The Seventh Doctor played scrabble against a Norse lighting god for the control plinth of Botoya's chroni-core. (AUDIO: The End of the Beginning)

Behind the scenes

 * Thor appears as a card in the Doctor Who: Trump Card Game released in 1978 by Jotastar.
 * Anthony Hopkins, who plays Odin in the Marvel Thor film series, was considered for Rassilon during the planning stages of the 1990s TV reboot.
 * Thor, identifiable through his iconic winged helmet and hammer Mjolnir, appears in The Incomplete Death's Head. Although probably intended to be consistent with the Marvel interpretation of the character (who, although the genuine Norse god, becomes a superhero in the present day), he was illustrated with a beard, which his then-current Marvel design lacked.
