Jane Foster was created by artist Jack Kirby and writers Larry Lieber and Stan Lee. This fictional character appears in comic books published by Marvel Comics and is portrayed by a high school student who falls in love with the superhero Thor Odinson.

Jane Foster is a character that has evolved in the Marvel Cinematic Universe, marked by torrid romances, adventures, and exciting fights. For many, this character was relegated to the background. Now she will reappear with a remarkable transformation in the upcoming Thor movie. Let’s see a little about this heroine.

Jane Foster’s Origin and Biography

Early Days

Jane had lost her mother, who died of cancer when she was only nine years old and was raised by her father, a plumber by trade. To give her everything deserved, her father worked two jobs so she could attend medical school. Her childhood was good, with a devoted father, who was always there, at her birthdays, and softball games, encouraging her in all her goals. Sadly, he later passed away from a heart attack.

Already graduated as a nurse, she was hired by Dr. Donald Blake, a lame doctor whose identity was used for many years by Thor, the Asgardian God. This superhero with two identities manages to make Jane fall in love with him, unaware that they are the same person, thus forming a love triangle that lasts a long time until Thor reveals his true identity. This revelation caused Thor to be punished by the god Odin.

Jane’s character was put under shadow when Sif is introduced, who officially appears as Thor’s bride in the comics, and who in fact in the original Norse myths is posed as such. So, Jane marries Doctor Keith Kincaid, with whom she has a son, Jimmy. This event practically liquidated the character of Jane Foster from the comics.

The Re-emergence of the Character

After 30 years, Jane appears not as a nurse but as a doctor, playing an important role as health personnel in Civil War, helping Captain America’s side, and assisting Spider-Man.

It is noteworthy that the character of Jane Foster appears in September 1962 for the first time in the comic Journey into Mystery #84. The story reveals that in 1978 and 2014, Jane handled Thor Odinson’s hammer, adopting the name of Thor, the Goddess of Thunder, so she joined the Avengers.

At that time, Jane was widowed, losing her husband and son in a car accident, and developing metastatic breast cancer. Thor invites her to Asgard for more advanced medical treatment than they could give her on Earth. This way is how she takes the hammer and becomes the new Thor.

The character’s new personality is given without revealing who she is. This fact infuriates the god Odison until he grants the blessing to his replacement. But, what they did not know, was that every time she took the hammer, her body got worse, reversing the chemotherapy, so the treatment she received, turned out harmless. This gives a bloody twist to the plot. In Secret Wars, 2015, all this is discovered.

So, for almost three years, we see her fighting with the Avengers, but these transformations leave her almost dead. Unfortunately, in her last fight against the villain Magog, where she is forced to retake the hammer, which costs her life.

But as in Marvel, no one dies forever; Odin takes pity on her, reviving her and allowing her to join the Valkyries. This Jane is now cured of cancer. She adopts the alias of Valkyrie, embodying the classic character we have seen.

Powers and abilities

Jane Foster gains all of Thor’s powers when she wields Mjolnir. This skill includes increased durability, superhuman strength, the ability to fly, and control over lightning and speed.

Jane Foster has a better command of Mjolnir than Thor. This heroine can change the speed and trajectory of the hammer, in addition to being able to trap her enemies by spinning it around them. Thor believes she is more worthy than him to wield the Mjolnir, so he favors her. 

Jane Foster also has a weapon called Undrjarn, which she wears strapped to her arm. The most important feature of this weapon is that it can transform into various objects, such as a sword or an arrow. When she is Valkyrie, she can use the Undrjarn to travel to the sky of the Asgardians (Valhalla). Jane Foster also can know if someone is going to die by looking over their heads.

The most important armament of this heroine is her bracelet, the Undrjarn, which was created from the remains of Mjolnir, which came from Earth in 1610. The Undrjarn the All-Weapon is transformed into different armaments, as she wishes.
