Hel is Loki's daughter and sister to the wolf Fenrir and serpent Jörmungandr and presides in the realm with the same name (the underworld). She was appointed by Odin to be the ruler of Hel (the location).
Her appearance is described as half-black and half-flesh colored, and also has a gloomy, down-cast appearance. She played a big role in the attempt to resurrect Baldr.
The phrase "Go to Hell" actually originated from "Go to Hel" meaning the same thing, which is "go die", since Hel was the name for both the ruler of the underworld as well as the name of the underworld.
She is said to be the only one capable of controlling the dragon Nidhoggr.
"The goddess of the underworld in Norse mythology. She lives in a hall called Eljudnir. Her father is the demon god Loki, and her mother is the giantess Angrboda. Her brothers are the giant wolf Fenrir and the world serpent Jormungandr. Together, these three are known as the "Calamitous Three." When Loki tricked Hodr into killing the god of light Baldr with a spear of mistletoe, Hel set an impossible task as a condition for restoring him to life. The world was thus robbed of light, signaling the beginning of Ragnarok. Hel rules over Niflheim, the realm of the dead, where she controls the fate of all dead souls in the world. Half of Hel's body is black and rotted, a symbol of her lordship over the dead and her role in judging all life."
