Many years ago, when Bor, ruler of Asgard, was battling frost giants, he followed a wounded giant to a powerful sorcerer that was waiting for him. The sorcerer caught him unaware, turning Bor into snow. Bor's son, Odin, found his father as he was blowing away; Bor begged Odin to find a sorcerer to free him, but Odin made no attempt to save his father. Bor cursed Odin saying that he would take in the son of a fallen king and raise it as his own. Not a week later, Odin himself led the Asgardians into battle against the Frost Giants and killed Laufey, who was the King, in personal combat. After slaying Laufey, Odin found a small Asgardian-sized child hidden within the primary stronghold of the Frost Giants. The child was Loki and Laufey had kept him hidden from his people due to his shame over his son's small size. Odin took the boy, out of a combination of pity, to appease his father, and because he was the son of a worthy adversary slain in honorable combat, and raised him as his son alongside his biological son Thor.

This guy who steals the Tesseract even though last time he did it he got caught. He is also Thor's adopted brother and Odin killed his real dad. HOW IRONIC. Oh, and he also pretends to die and fakes being Odin. Man, his sceptre is so cool. NOT A EUPHOMISM.

A very unusually feisty orange tabby cat. He will attack you while purring, and will always want a snack, but most of the time, he is a sweet kitten. Lokis are usually found close to Chesapeakes.
"I met a Loki today."
"Oh! Did it scratch you?"
"Yup."
"Too bad. I heard Lokis could be nice when they're in a good mood."
