Thor has a complicated relationship with his villain/anti-hero of a brother. Who is this Asgardian villain that was the first foe of the Avengers?

Loki was the biological son of Laufey, king of the Frost Giants, and adopted son of Odin, king of Asgard. After a fight with his brother Thor, Loki escaped and made a deal with Thanos to lead an invasion of Earth, which was eventually stopped by the Avengers.
