Thor is one of the best characters to come out of the Marvel universe. He is big, strong, powerful but most importantly he is human. When I say human, I mean he has human emotions; he is actually a Norse god.
This is a great 60's cartoon right up there with Spider-Man and Captain America. The stories were great. Throughout the series Thor travelled to Earth from Asgard to battle all kinds of foes and to also spend time with the love of his life Jane Foster.
One of the things I liked about Thor was his secret identity. When not Thor, he would assume the identity of the crippled Dr. Donald Blake. Whenever there was trouble Blake would strike his walking stick on the ground, the stick would become a hammer and Blake would become Thor.
To sum it up, The Mighty Thor was a great series with a great theme tune. My personal favourite episode was "Enter Hercules" where Thor faces fellow god Hercules in one of the best cartoon battles ever.
