Sif (MCU)

Lady Sif is a fearsome Asgardian warrior and a good friend of Thor and the Warriors Three. When Thor almost provoked a war with the Frost Giants and ended up powerless on Earth, Sif and her friends disobeyed the orders of their new king Loki and went to Earth to save him. Thanks to them, Thor returned to Asgard and Loki's reign came to an end. Sif then bravely fought against the Marauders, an intergalactic ragtag band of pirates who pillaged the unprotected realms of the universe. After the Second Dark Elf Conflict, she was sent to Earth to capture the sorceress Lorelei. A year later, Sif returned to Earth again to investigate the arrival of the Kree Vin-Tak, who was hunting Inhumans. In 2018, Sif was among the many victims of Thanos' Snap. However, she was resurrected five years later by Hulk.
