Loki Laufeydottir also known as Sylvie is a Marvel minifigure introduced in the 71031 Marvel Studios Series. She features in the Disney+ original series Loki. She is a alternate timeline variant of Loki.
Sylvie Laufeydottir is a variant of Loki Laufeyson. Having escaped the Time Variance Authority's punishment for causing a Nexus event, Sylvie hid through out the timelines, while seeking revenge against the TVA and the Time-Keepers. On the cusp of her plan's success, however, she was interrupted by another Loki Variant, (who after the Battle of New York escaped the custody of the Avengers during the Time Heist), whom she eventually formed an uneasy alliance with. Having convinced Loki of the TVA's lies and manipulations, they worked together to fight them, discovering the Time-Keepers were a fakes. With her only ally being Loki, Sylvie followed him into the Void, in the wake of Ravonna Renslayer sending him there, where they eventually found and confronted He Who Remains, the creator of the TVA. Despite warnings from Loki about the consequences of doing so, Sylvie enacted her revenge and killed He Who Remains, causing the Multiverse to split apart, and Kang the Conqueror to gain power.
