"Is it play time yet?"
-Loki's second line when entering the game.
Loki is one of the Blind Bag characters in LEGO Dimensions 2: The Rise of Enoch, from the Marvel Comics franchise.
Loki was the son and heir to the Frost Giant, King Laufey who was disdainful towards his son due to Loki having been born the size of an Asgardian. When Loki was only a child he witnessed his father be slain in battle by Odin who took pity on the young Frost Giant and adopted him as his own son.
In Asgard, Loki was very much ostracized for his lineage while being seen as weak and lesser due to his scrawny but intelligent nature, especially when compared to his step-brother Thor. This lead Loki to assume the moniker of "The God of Mischief" in order to satisfy his darker urges and feelings of invalidation but as the eras passed, Loki's schemes became far less playful and far more evil. Loki attempted to conquer Asgard on multiple occasions but ultimately he was imprisoned within a tree under the orders of Odin where the Trickster remained imprisoned for decades until he was freed during the 1970s.
After this, Loki became intent on destroying his brother and taking his father's throne by whatever means necessary, even inadvertently forming the Avengers at one point.
