## Biography

### Early Life

#### Respected Warrior

*"And who proved wrong all who scoffed at the idea that a young maiden could be one of the fiercest warriors this realm has ever known?""I did!""True, but I supported you, Sif."*
―Thor and Sif[src]
During her early years, Sif's great talents as a warrior were not appreciated by many because she was a woman. Thanks to her friend Thor, whom she developed romantic feelings for, Sif became one of the most appreciated warriors of Asgard, along with the Warriors Three, Loki, and Thor himself.

#### Loki's Mischief

Sif visited Earth along with her friends in the 11th century, and Loki's mischievous act of cutting a lock of her hair on Asgard became a well-known tale in Norse mythology.

### Loki's Schemes

#### Thor's Royal Coronation

*"My father fought his way into Jotunheim. Defeated their armies and took their Casket! We would just be looking for answers.""It is forbidden!"*
―Thor and Sif[src]
Lady Sif, alongside Loki and the Warriors Three, were present at the coronation ceremony for Thor, who was to be crowned King of Asgard as the current King Odin believed he was becoming too old. Ahead of the ceremony, Lady Sif was asked to hand over all of her weapons by a member of the Einherjar. Sif complied; however, the guard stopped her and then forced Sif to hand over the final hidden blade she had been secretly attempting to keep concealed.

Lady Sif then joined the other Warriors Three as they awaited Thor's arrival. While they were all waiting, Volstagg complained about still being hungry, which Fandral teased him about, with Volstagg then jokingly threatening to hit Fandral as a result of his mockery. Sif then listened with amusement as Fandral teased Hogun by insisting that he consider smiling at least once for their event while Lady Sif then challenged him to keep his mouth shut during the ceremony.

Sif watched as Thor arrived confidently, throwing his hammer Mjølnir in the air and winking at Sif, much to her disapproval. Sif then stood by next to Loki and Frigga as Odin made Thor swear to protect all of the Nine Realms. However, when the Frost Giants interrupted Thor's coronation ceremony in a desperate attempt to steal back the Casket of Ancient Winters only to all quickly be killed by the Destroyer, the coronation was canceled, much to Thor's considerable anger.

Sif and the Warriors eventually found Thor throwing tables in the air in rage due to his failure to become King, as Odin had deemed him to not be ready for the responsibility. They arrived just when Loki was trying to calm his own brother down, while Thor was adamant that the Frost Giants should be punished for the sudden attack and the disgrace and embarrassment this had caused him, with Sif and the Warriors still keeping their distance from the furious Thor.

Thor then went to all of his own friends individually to tell them why they should follow him, gaining Fandral, Hogun and Volstagg's strong support. When Thor came to Sif, he asked her who had proved wrong all those who had stood in her way when she had planned to be the fiercest warrior in all of Asgard, but Sif insisted that she had done it alone, which Thor did not argue with. Despite this going against all of Odin's direct orders, the group still chose to follow Thor's plan.

#### Attack on Jotunheim

*"We should have never let him go!""There was no stopping him."*
―Volstagg and Sif
Lady Sif along with Loki and the Warriors Three, having now all been convinced by Thor to attack Jotunheim to find those responsible for the attack. They did not struggle to get past Heimdall, who had also wanted to learn who was responsible for the attack. Heimdall transported them to the home of the Frost Giants, but told them he would not risk Asgard's safety and would not hesitate to leave them to die in Jotunheim.

Using the Bifrost Bridge, Lady Sif and all of her allies soon arrived on Jotunheim, finding it to be a cold wasteland as Hogun warned that they should not be there. As they walked throughout the realm, Sif questioned where the Frost Giants were, to which Thor claimed that they were hiding. Once they found him, Thor and Loki attempted to negotiate with Laufey, the King of the Frost Giants. Thor was insulted by a Frost Giant and began a huge battle with their enemy.

As the enraged Frost Giants charged into battle, Lady Sif then armed herself with her Sword and Shield as she fought alongside her friends against an army of Frost Giants led by Laufey himself, and managed to slay many of them, but was forced to flee when Fandral had been wounded and they became outnumbered. Sif and the Warriors Three attempted to outrun the giant Frost Beast sent after them; they were soon cornered by the creature, which was killed by Thor.

Eventually, the team was saved by Odin himself, riding Sleipnir, who intervened to prevent them all from being killed by the Frost Giants. Although Odin tried to bring about peace between Asgard and Jotunheim, Laufey told him that war was to begin because of Thor's actions. With their decision to return to war made, they were taken back to Asgard, and Sif witnessed Odin's decision to punish Thor by taking his power and banishing him to Earth, with Sif helpless.

#### Thor's Banishment

*"He may speak for the good of Asgard, but he's always been jealous of Thor.""We should be grateful to him. He saved our lives."*
―Sif and Volstagg[src]
In the wake of Thor's banishment, Sif and the Warriors Three had all gathered together, along with Loki, to discuss what had happened and what should be done as a result. While Fandral and Volstagg recovered from their injuries sustained during the Attack on Jotunheim, they discussed the events on Jotunheim, questioning how Odin could have learned of their activities: However, Loki suddenly revealed that he had informed Odin of their attack on Jotunheim.

Horrified to learn that Loki had betrayed his own brother resulting in Thor's banishment from Asgard, Sif tried to convince Loki to speak to Odin but Loki refused, claiming Thor was too foolish to be their King. Once Loki had left the room, Sif noted that Loki was jealous of Thor while Hogun told the group that he believed Loki was responsible for the original attack on Asgard, noting that the master of Magic could have been able to sneak the Frost Giants past Heimdall's watch.

Determined to get Thor back onto Asgard to stop the risk of Loki's schemes being successful, Sif persuaded the Warriors Three to ask King Odin to recall Thor back home, but when they arrived inside the throne room, they found Loki sitting as the new ruler of Asgard, as a substitute to Odin, who had fallen into the Odinsleep. When they had suggested speaking to Queen Frigga instead, Loki insisted that they speak to him, ordering the group to bow before their King.

Although she was reluctant, Sif and the others took a knee before Loki and asked him to end Thor's banishment, only for Loki to deny their request as he claimed his first action as King could not be to undo Odin's last, insisting that the Asgardians needed a sense on continuity. When Sif tried to get to her feet, Fandral pulled her back before Volstagg tried again and Loki demanded that they leave, Sif glaring at her King before then walking away from him.

#### Disobeying the King

*"Is it just me or does Earth look a little different to you now?""It has been a thousand years.""Changes happen so fast. I mean, you leave for a millennium and look at the state of the place."*
―Volstagg and Sif[src]
Following this denial the Warriors Three's relationship became more and more strained, leading to an argument between Fandral and Volstagg, which Sif and Hogun broke up. When everyone calmed down, they agreed they must go to Midgard to retrieve Thor and bring him back to Asgard to oppose Loki's rule, regardless of this being seen as treason.

Before they were able to enact their plan Sif and the Warriors Three were called for a meeting with the all-seeing Heimdall, as Volstagg summed up all of their feelings by simply saying "We're doomed", believing that Heimdall must have overheard their treasonous plans. However, Heimdall agreed with the team's plan to oppose the rule of Loki and opened the Bifrost Bridge for them, and the four Asgardians arrived on Earth in order to find Thor and bring him home.

Upon arriving inside a town named Puente Antiguo, the team began searching for their ally, being spotted by S.H.I.E.L.D. agents who referred to Sif as Xena. Having searched for just a few minutes, they spotted Thor and they happily greeted him and were introduced to Thor's new friend, Jane Foster, who were amazed to see the Asgardians had arrived in search for Thor as they watched Sif and the other embrace their dear friend.

Having delighted in being reunited, informed told Thor that they were there to bring him back to Asgard, but Thor had appeared confused, claiming he could not return home as his own actions had caused the death of Odin and his exile would maintain the peace between Asgard and Jotunheim. However, Sif assured him that Odin was still alive. Thor and the team then found out that he had been tricked by King Loki in his attempt to ensure Thor never returned home.

#### Battle of Puente Antiguo

*"Sif, you’ve done all you can.""No! I will die a warrior's death. Stories will be told of this day.""Live, and tell those stories yourself."*
―Thor and Sif[src]
Shortly afterwards, Loki sent the Destroyer to Earth to make sure that Thor will not return. Thor told them that he was powerless in the fight against the Destroyer so choose instead to help the innocent people of Puente Antiguo to safety. Sif and their allies then engaged the Destroyer in battle.

As the Warriors Three bought her some more time by distracting the Destroyer as they launched Volstagg towards the machine, Sif got to higher ground before she jumped from a nearby rooftop onto the robot's back, attacking the Destroyer from above, piercing its chest with her sword. While Sif was still confident about the easy victory, however, immediately after the attack, the Destroyer had regenerated itself and almost killed Sif with an energy blast from its eyes.

As the Destroyer seemed unstoppable, Thor tried to convince Sif to flee with her companions while Fandral and Hogun were helping Volstagg back onto his feet, insisting that she had done everything that she could. Determined to continue the fight, Sif bravely told Thor that she intended to die a warrior's death and have stories told about her sacrifice; however, Thor was able to convince her to live and tell the stories herself, so Sif then reluctantly made her escape.

Now alone against the Destroyer, Thor, who claimed to have a plan, challenged the unstoppable creature with his words. Sif watched on helplessly as Thor sacrificed himself to protect the innocent people, offering his own life in exchange to allow them to live. The Destroyer hit Thor and he died, but because of his noble sacrifice, Mjølnir had returned into his hand and he was reborn in his divine form, in which he fought and destroyed the Destroyer as Sif watched on.

In the wake of the battle against the Destroyer, Sif, Thor and the Warriors Three prepared to leave Earth and return to Asgard, leaving Phil Coulson to deal with the aftermath. However, Heimdall had been injured by Loki using the Casket of Ancient Winters and took longer than expected to open the Bifrost Bridge to bring them home, at which point Sif and the Warriors then took Heimdall, to the healing room while Thor went to challenge his brother personally.

#### Returning to Asgard

*"My Queen, I'm so sorry for your loss. How is he?""He mourns for his brother. And... he misses her, the mortal."*
―Sif and Frigga[src]
Back in Asgard, while Sif took Heimdall into the healing room, Thor had successfully defeated Loki and Odin retook the throne of Asgard. Along with other Asgardians, Lady Sif celebrated the victory with a banquet. Sif saw Thor silently leave the celebrations and watched him go. Sif joined Frigga, the mother of Thor as Sif offered Frigga her condolences for Loki's death and Frigga asked Sif how Thor was coping.

Frigga informed Sif that while Thor mourned for his brother, he was also missing Jane Foster on Earth.
