Loki Laufeyson (sometimes Odinson) is the adopted brother of Thor and is the god of mischief, outcasts, stories, lies, etc. He is portrayed by Tom Hiddleston in the Marvel cinematic universe.
Though he is a shapeshifter, his usual appearance is that of a thin young man with shoulder-length black hair, green leather armor made from fine Asgardian leather with gold trimmings, and either a golden horned helmet or simpler horned headwear.
Within the comic universe, Loki was confirmed to be canonically genderfluid as of the release of the Agent of Asgard comics. Thus, the god occasionally switches between looking masculine and feminine.
