Then and now, Thor was one of the most popular Gods of the Norse pantheon. Though called the son of Odin, there are other accounts that claimed he was older than Odin.
This may have been because of his popularity. Of all the Norse Gods and Goddesses his followers numbered the most, while there were few, if any members of the cult of Odin, he being considered to remote and frankly treacherous, there were thousands of followers and priests of the God of Thunder.
Thor it seems was a god of the people, much as Hercules was to the Greeks, Quetzalcoatl was to the Aztecs, or Gilgamesh was to his people.
Today of course, in comics at least, most people know of Thor through the Marvel comic books version.
However other versions have been used in comics, A Thor who gained superpowers from a lightning stroke appeared in Weird Comics for 5 issues in the 40s, in the late 50s Thor appeared in the pages of Batman Comics where the dynamic duo encountered him as a one shot Bat-Villain; until it turned out that he was just a little guy who turned into Thor by holding his hammer which was made from a glowing meteor tied to a stick, while at the same time in Tsampiyon Komiks in the Philippine a series was run detailing the story of the human who adventures were the basic for the myth that would become Thor.
Other versions of Thor have appeared in Donald Duck comics, David Brin's The Life Eaters, Rob Liefeld's Youngblood, Erik Larsen's Savage Dragon, and from Argentina, El Cazador de Aventuras the story of the Ragnarok, a few comics from Amryl, and even for two issues of the Inferior Five in the 60s, showing that not all comics book Thor’s are blonde, from Marvel, or even always heroes.
