Jotun

 is a slaver at Paradise Falls, the son of Ymir and he appears to also be his bodyguard. He doesn't have a major role in Fallout 3. He stands around inside Paradise Falls and only briefly mentions he is there to keep his father safe. When you talk to him, his dialogue indicates that he is incredibly unintelligent. He is equipped with Metal Armor and a Super Sledge. Jotun stays friendly in fights occurring in Paradise Falls until he or his father are attacked.

Bugs

 * Sometimes (rarely) if you have very good karma and you enter the barracks he will ask you to leave three times. If you stay he may turn hostile on the third warning and in-turn resulting in all the Paradise Falls slavers turning hostile. However, if you talk to him before the third warning he shouldn't attack you at all.

Appearances
appears only in Fallout 3.

Trivia

 * In Norse mythology, Jotun was the name given to giants, the enemy of the Aesir.
