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 occuring in Paradise Falls until he or his father are attacked.

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