Sif (Earth-11584)

History
The Lady Sif was an Asgardian warrior who lived during the reign of King Odin. Often considered a modern day Valkyrie, Sif was considered one of the foremost warriors of Asgard, her talents for combat and battle almost going unnoticed due to her gender, but given her due recognition due to her friendship with Thor and the Warriors Three. In time, she became closely allied to the group, and obviously to most (though apparently not to Thor himself) harbored romantic feelings for the future king. Sif never acted upon these feelings, deciding it was not her place to do so.

Sif was present during Thor's attempted coronation to become the new king of Asgard, genuinely happy for her best friend. However this joy was replaced when Frost Giants snuck into Asgard and disrupted to proceedings. Though the invaders were dealt with quickly, Thor was incensed at the audacity of their ancient enemy, and sought revenge against Laufey. Sif was convinced to join the company of warriors accompanying Thor on his unauthorized mission to Jotunheim, though quickly they realized they were in over their head. Sif and the others were rescued by Odin, and Sif accompanied the wounded Fandral and the Warriors Three to the infirmary, only later learning of her friend's banishment to Earth.

Powers & Abilities

 * Asgardian Physiology: Being an Asgardian, Sif possessed a lifespan far greater than that of normal human beings. She also possessed enhanced strength and durability compared to other sentient beings.
 * Master Combatant: It could be argued that Sif is the best all-around fighter in the entirety of the Asgardian army. She has been referred to as a Modern Day Valkyrie, earning comparison to the fabled fighting legions of Asgard disbanded many years prior. Her preferred method of combat was with a two-handed, double bladed sword, but she also showed great prowess with the Dragonfang Sword (itself the fabled weapon of the Valkyries) as well as with a bow and arrow.

Weaknesses
Of all the Asgardian warriors, Sif likely had the fewest number of weaknesses overall, though like most Asgardians she was quick-tempered and quick to act in the face of an insult. Her unrequited feelings for Thor ingendered jealousy for Jane Foster for a time, though that didn't stop Sif from laying her life on the line to protect her when the Dark Elves came looking for the Aether.
