The infamous Trickster God Loki has been making waves in the MCU for quite some time now. Currently, he is jumping through the timeline with the Time Variance Authority while planning to grab power from them at the first opportunity. In the comics, he has done numerous schemes that have given him massive amounts of power.
Throughout the decades his character has evolved from pure evil villain to lost young boy to being the steward of magic in the mainstream Marvel Universe. Suffice to say, Loki is a versatile character that can be used in a variety of storylines. One never knows where he will appear next or even what he will look like. One thing is certain though, Loki will always find a way to end up on top.
10 Imprisoned In A Tree
From 1933 to 1951, Loki was a true menace to Midgard and all of humanity in general. From spending time at the Ravencroft Institute to casting a spell over the entire nation of Cassarobia, Loki caused nothing but trouble. Time after time Thor was sent to handle Loki and drag him back to Asgard.
This did nothing to sway the Trickster God as he would continually cause chaos and mischief throughout the Nine Realms. At one point he made several trespasses against the Greek Gods and Olympus itself. Odin finally got tired of these antics and trapped Loki in a tree using his powerful magical abilities. The only way he could escape was if someone shed a tear for him.
9 Created The Absorbing Man
Thor has battled against Crusher Creel aka The Absorbing Man on many occasions. In fact, many Marvel heroes have battled Creel and found him to be a tough opponent. The reason that Creel is so formidable is that Loki imbued him with his absorbing powers.
Through his powerful magic, Creel has been able to go toe to toe with such powerhouses like the Hulk more than a few times. While Creel might not be a criminal mastermind, his powers make him an Avengers-level threat. Once again Loki has created something that will plague the heroes of the Marvel Universe for a long time.
8 Acts Of Vengeance
What would happen if all the biggest villains in the Marvel Universe banded together and switched adversaries? In 1989, this question was answered in the "Acts Of Vengeance" storyline that ran across multiple Marvel titles. Ingeniously, Loki managed to convince the Red Skull, Doctor Doom, Magneto, Kingpin, Wizard, and the Mandarin to join forces and fight heroes that they had never faced before.
The kicker is that he managed to make them all think that this was their idea while pretending to be a mere grunt. While the truth came out eventually, Loki's plan almost succeeded and the aftereffects of it were felt for years.
7 Numerous Children
Norse Mythology focuses on the three most powerful children of Loki: Fenrir, Hela, and the Midgard Serpent. While they have each made many appearances in the comics, Loki actually has many more children roaming around Earth. This is a rare weak spot of his and it was once exploited by the powerful being known as Morwen.
In a Spider-Man storyline called "Chasing a Dark Shadow" Loki had to team up with the wallcrawler in order to save the life of his daughter Tess. Loki showed a very rare moment of humanity and even love in how he spoke about his many children across Midgard.
6 Ragnarok
The ancient stories of Ragnarok aka the end of the world all state that Loki has a huge role to play. As a matter of fact, he not only starts it but it was only made possible because of his actions. When Ragnarok finally came to Asgard in the comics Loki played his part. He led the enemies of Asgard to its gates and let them in, all while enjoying the destruction they caused.
However, Loki finally realized that he was just a pawn in a much larger game. Ragnarok is destined to happen over and over again, with Loki being a mere tool for Those Who Sit Above In Shadow. These beings played him like a fiddle and were the reason that Ragnarok happened over and over again. Eventually, Thor with a little help from Loki, ended the cycle and ensured that the Asgardians could control their own fate.
5 The Cabal
After the events of Ragnarok, Loki underwent several changes. For one, he was now a woman and a part of quite possibly the most powerful group of villains the Marvel Universe had seen at that point. The reason they were so powerful is that Norman Osborn had almost complete control of America and its various defense agencies.
During this time Loki revealed to Baldur the truth of his parentage, imprisoned Sif in the body of a dying old woman, and played Norman Osborn for a fool. Loki was quite triumphant in this part of his history, if not for the efforts of almost all the Marvel Heroes during the storyline "Siege" he would have ruled over all the Nine Realms.
4 Impersonating The Scarlet Witch
During the same time that Loki was a member of the Cabal, she became interested in Norman Osborn. She wanted to return him to his unhinged state and used the Mighty Avengers to do so.
By impersonating the Scarlet Witch she was able to manipulate the entire team into doing her bidding. Quicksilver and Cassandra Lang were the first to suspect her plot by fell prey to her powerful magical abilities. Eventually, the truth was revealed and she escaped to finally push Osborn over the edge in "Siege".
3 Kid Loki
Once Loki's machinations were revealed to the world at large, he came into battle with The Void. This being is the dark side of the super powerful anti-hero known as Sentry. Even Loki could not withstand The Void's might and he fell in battle. Refusing the loose his brother, Thor searched for his brother and found him reborn as Kid Loki. This rebirth gave Loki a new lease on life as he had no memories of his past deeds and was free to chart his course for the future.
2 Young Avengers
After a few adventures, Kid Loki had managed to beat back the spirit of his older self and began to forge his own destiny. This led to him meeting the Young Avengers and joining their ranks. Even though he still felt a pull to the darker side of his nature he fought against it.
During the battle against Mother, Kid Loki came face to face with a version of himself that claimed to be his guilty conscience. While refusing to believe this being, he tried his best to be a hero. Eventually, it was revealed that the being was telling the truth and he had to confront the actions of his previous self.
1 Sorcerer Supreme
After undergoing another transformation in which he was now closer to a teen or twenty year old, Loki made a power move. He decided that Earth was not ready for potential magical threats due to Dr. Strange's incompetence as Sorcerer Supreme. Through deception and lies, Loki tricked Strange into giving him the mantle of Sorcerer Supreme.
He searched for a spell that would grant him all the magical powers on Earth while assisting the planet against several adversaries. Everything came to a head when Strange and a few allies forced Loki to fight The Void once again. During this battle, Loki confessed the truth to Strange, vanquished The Void, and returned all magic to Earth.
