Most dangerous villain? Brr! Is it the Infinity stones’ hunter or the goddess of death? Neither. It’s a low-key, ambitious, smooth-talker with great hair: Loki, god of mischief.
The Most Dangerous?
Loki is an amalgam of superpowers. His abilities include, but are not limited, to invisibility, shape shifting, telekinesis, and, of course, illusion casting. Personality-wise, he's mischievous (and proud to be), acutely aware of others' weaknesses, patient, and loyal to no one but himself. Quite a lethal combo!
Loki Laufeyson made his debut in the MCU as the insecure yet ingenious villain who challenged Thor in their first movie. He supposedly died at the end when he let go of Thor’s hammer to fall into an abyss out of despair. However, he reappeared a couple of years later to prompt the gathering of six of the universe's mightiest heroes in The Avengers.
From then, he alternatively wore the villain mask and the hero’s. For example, he helped Thor fight against Malakith then trick Odin into giving him the throne in Thor: The Dark World. In Thor: Ragnarok, he helped evacuate Asgard but stole the Tesseract, thus leading Thanos to them. Afterward, in Avengers: Infinity War, the impossible happened in the first ten minutes: Loki is strangled to death by Thanos. And even the Mad Titan stated, “No resurrection this time.” Well, he was wrong because the past version of Loki managed to escape using the Tesseract in Avengers: Endgame while two beloved superheroes are gone.
Loki is the most dangerous villain of the MCU because he's immortal. Physically, he can die, but he’s the only villain who has an established place in the MCU. He will always come back. After all, he currently has his own television series. This privilege came from his popularity among the MCU fans. Despite his thirst for power, Loki has some attractive qualities, such as his wit and intelligence. He is also a villain with apparent internal struggles. Since Thor (2011), it has been shown that Loki struggles with identity crisis and insecurity. His character is presented with vibrant vulnerability; he’s the only villain whose heart is left open to peek in.
Loki: the villain with a choice
Loki is also the only villain who seems to be able to choose his path. He has the luxury to switch between being a villain or a hero and still thrive either way. In Loki, he escaped as a villain but was still given a chance to help the TVA. Therefore, his future in the multiverse remains unpredictable but inevitable. One thing to keep in mind is that if Marvel decides to use him as a villain in the future, he will be unstoppable. His villain resumé will showcase that he has centuries of experience and considerable transferrable skills.
