Giant is an organism that a big size and strongly in Norse mythology. Giant usually hate the god, especially with the God of Aesir. Giant also called Jotun or Iotun or Troll.

There is some kind of giant. The general giant is the giant ice, they are lived in Jotunheim, one of nine in the world. The capital city of Jotunheim is Utgard, there is Utgard-Loki or Utgardaloki lived. Other called for the world of the giant is Land of The Giants.

Land of The Giants or Jotunheim is the huge place. The location is in the north Midgard, separated by river and jungle or you can called Jarnvid (Iron Jungle). Jarnvid is inhabited by the female troll, Jarnvidjur. They are giving birth a giant with wolf shape.
Be sides Utgard, so many places in Jounheim. Hrungnit giant lived in Land of The Giants border, Griotunagardar. Thiassi giant lived in Thrymheim mountain with his daughter, Skadi.
The other type of giant is fire giant that lived in Muspelheim. Surt becomes a master there.
Some of the giant females are to be the god because they are married to the goddess. An example is Jord, Grid, Gerd, and Rind. They are to be the god of Aesir.
Many gods of Aesir is generation or klan from the giant. An example is Odin, Thor, Tyr, and Heimdall. Don't forget with Loki, because his parents are giant. Loki is to be a leader of the giant of ice in Ragnarok.

According to the mythology, Loki or Loke is not god.

He not from Æsir or Vanir, he is a Jotun. However because he is close to Odin, he considered as Æsir. Loki is a god of mischief. He is like Hermes in Greek Mythology. He often changes his form to be more form to easily do the trick. Loki was the father of many creatures, men and monsters. With Glut, his first wife, he was the father of Einmyria and Eisa. Having liaisons with giantesses was nothing unusual for gods in Norse mythology—both Odin and Freyr are good examples; and since Loki was actually a giant himself, there is nothing unusual about this activity. Together with Angerboda, he had three children:

*Jormungand, the sea serpent

*Fenrisulfr the giant wolf preordained to slay Odin at the time of Ragnarok

* Hel, the goddess of the underworld/realm of the dead

Let me tell you one story about Loki.

Thrym giant stole Mjolnir (Thor's hammer) and won't return it. Thrym giant said if Freya to be his wife, he will return the hammer. Thor asks Freya about arrangement's Thrym giant. She angry to heard that and don't want to be Thrym's wife. Certainly.

Thor disguised as Freya and Loki disguised as Freya's servant. They are going to the land of the giants. After they arrived, Thrym and the giants believe that they are Freya and her servant, even thought Thor is so bad to disguised as Freya. The example is Thor ate one ox and three barrel mead and when Thrym wants to kiss her, he sees that Freya's eyes glowing red. But Loki -with the cunning- explain, and Thrym believes that.

At the wedding ceremony,

Thrym brings the hammer and gives to Freya -actually Thor- and quickly Thor grabs the hammer and fighting the giants. And then, they come back home with the hammer.

Not all lore depicts Loki as a malevolent being.

An 18th-century ballad from the Faroe Islands, entitled Loka Thaattur, depicts Loki as a friend to man, like a Prometheus in Greek mythology. When a thurs (troll or giant) comes to take a farmers son away, the farmer and his wife pray to Odin to protect him. Odin hides the son in a field of wheat, but the thurs finds him. Odin rescues the son and takes him back to the farmer and his wife, saying that he is done hiding the son. The couple then prays to Honir, who hides the son in the neck-feathers of a swan, but again the Thurs finds him. On the third day, they pray to Loki, who hides the son amidst the eggs of a flounder. The thurs finds the flounder, but Loki instructs the boy to run into a boathouse. The giant gets his head caught in a peephole (the translation is not complete, but it appears to be a peephole) and Loki kills him by chopping off his leg and inserting a stick and a stone in the leg stump to prevent the thurs from regenerating. He takes the boy home, and the farmer and his wife embrace both of them.

Thiassi or Thiazi

Thiassi or Thiazi is the giant ice of Olvaldi or Alvaldi. He has brothers, Idi and Gang. He has the power of change to be an eagle and has one daughter, Skadi. His father is very rich and live in Thryeim. After his father death, the land is divided into three parts for three brothers.

Thiassi kidnapped Iduna,

Thiassi --with helping from Loki-- kidnapped Iduna, ageless apple guard and her apples of eternal youth. In the form of an eagle, he carried off Loki and kept him dangling from a staff with which he had struck the bird until he promised to get for Thiassi the two things he wanted most. Loki tricked Iduna into going outside the borders of Asgard with a bowl of apples and she was immediately abducted by Thiassi. She refused to let him eat any of the apples and when the gods found out what had happened, they ordered Loki to get Iduna back meanwhile Thiassi hunting down Loki until Asgar with form a giant eagle. But he murdered by the gods of Aeisr when through the Asgard wall.

After that,

Odin takes Thiassi's eyes and throwing in the sky. And then the eyes is to be two stars. Skadi is going to avenge his father's death but the Gods make an appointment. Do you know what the appointment? Let's check THIS!

Skadi [Kaw-dee] is also known as Skade, Skadhi or Skathi. Skadi is a giant ice and daughter of giant Thiassi from Thryheim Mount. Skadi was born into the heroic, mythical world of Asgard, the heavenly home of the fierce Norse gods and of slain heroes. Tall, beautiful, and a formidable warrior and hunter, the goddess was a force to be reckoned with.

When do you call upon Skadi?

Call upon her when you need help moving from the dark into the light.
She is stormy and unpredictable, relentless in her pursuit of what she perceives as justice. She will stop at nothing to achieve her objectives. But she has passion and integrity, and the determination to live life in all its fullness, regardless of the harshness of her circumstances, or of the feelings of others about her. She knows how to survive in a tough climate, how to provide for herself and her loved ones. She loves winter because it calls forth the best in her. It demands her strength and courage, not her weakness. It calls for her patience, and her understanding that there is a cycle of seasons in life, and that winter is an essential part of that cycle.

Skadi is going to war.

Skadi is going war with Aesir Gods because they are has been killed her father. But the Gods make an appointment that if one of them can make her laugh, Skadi can choose who will her husband.

Loki, the Trickster, provided her laugh at great personal expense, but to choose a husband for Skadi is difficult. Skadi chooses her husband from their feet. She chooses the most attractive set of feet, believing them to be his. So, instead of the handsome Baldur, she picked the homely sea god, Njord. She didn’t get her heart’s desire. Still, she kept her word, and stoically went through with the marriage. It was doomed from the start.

But that is no longer, Njord liked to live beside the sea while Skadi was happy only in the mountains with her beloved wolves. So they are divorced.

After that,

Skadi is married with the god of winter, Ull. Like the other giant was married with god, she is to be Norse Goddess of Winter.
