Hela, the Goddess of Death, is a prominent character in the Marvel Universe, particularly associated with Thor. She is the firstborn child of Odin and the older sister of Thor and Loki, although she was often forgotten by history as Odin sought to hide her existence due to her violent tendencies and ambitions. Initially depicted in the comics as a force of destruction, Hela's character evolved over numerous story arcs, showcasing her burdens and motivations tied closely to Asgard's throne. She made her cinematic debut in 'Thor: Ragnarok', where she challenged Thor’s authority and sought to reclaim Asgard as her domain. Hela is not bound by traditional morals, seeing herself as a rightful ruler unafraid to exert her power through fear and dominance. Her implications on power dynamics within Asgard have resonated, making her on-screen portrayal one of the more compelling villainous roles in the franchise. In comics, she has appeared in significant arcs like 'Siege' and 'The Mighty Thor', emphasizing her formidable presence across various narratives. Overall, Hela represents both a family legacy and a struggle against her own nature, ultimately portraying the complexities of being a powerful female antagonist in the Marvel landscape.
