When Loki first appeared on the big screen in Thor (2011), he was introduced as a one-dimensional villain, driven by jealousy and a desire for power. His actions, though cunning and clever, were seemingly motivated by a simple desire to supplant his adoptive brother, Thor, as the favored son of Odin. However, as the MCU progressed, Loki's character underwent a significant transformation. In The Avengers (2012), his machinations revealed a more calculated and cerebral approach, showcasing his intelligence and magical prowess.
