Loki

Loki is a god in Norse mythology who is often simply described as the 'trickster' god for his love of playing pranks on both his fellow gods and his or their opponents. Sworn brother of Odin and often the one to dig the other gods out of inconveniently deep holes, Loki's name nonetheless has many negative connotations due to his deceitful nature and especially the hand he had in the death of the god Baldr, thus setting in motion the coming of the Ragnarök (the 'final destiny of the gods' in which the world is destroyed). With no cult attached to him and no clear function in Viking Age belief, yet being one of only three gods who headlines in more than one myth (the other two being Odin and Thor), Loki takes up a unique spot in the Norse pantheon.
