Troll

A troll is just one of many names creatures from the Jotnar tribe were given by the vikings. There were wolves, serpents and other creatures dangerous to the Vikings that were born from a Jotun woman.

This is not a character mentioned specifically in the myths, but rather one of the many Jotuns that spawned out of the frost giant Ymir's body. He is by far the scariest of all the characters in the movie.

The viking religion was not about good vs. evil, but order vs. chaos, which is a philosophical way of saying human vs. nature. The Aesir (the gods) were very "viking" in their behavior and could do really cruel things. However, as this film is for little kids, good vs. evil is easier to understand, so this troll was designed specifically to send the message that the Jotnar are evil. His long limbs and short torso are to resemble a spider, his skinny body to bring associations with disease, and his zombie-like blank eyeballs radiates death.

Tomorrow I will post the six-headed son parented by Ymir's two feet.
