For other characters based on the same mythological figure see: Thor.

Thor is a Valhallan warrior who was one of those who visited Earth thousands of years ago. He possesses a magic hammer and magic gloves. He is described as the only one who can defeat the Frost Giants which often wage war against the Valhallans.

His species seems to be immortal, and he claims that he has never been a child. Additionally, the other Valhallans are only vaguely familiar with the concept of childhood.

Despite his strength and bravery, Thor is a naïve and not particularly bright fellow. When drunk he can become easily insecure about his own ability to defeat the Frost Giants.
