Big book of Marvel Facts!!

Loki

So here's the story if you watched the video... Also this is my favorite Loki video I've watched so far!!

Loki Laufeyson is an Asgardian prince, the God of Mischief and usurper of the Asgardian throne. A misshapen Frost Giant, he is the adopted brother and nemesis of Thor, the adopted son of Odin and Frigga, and the biological son of the Frost Giant Laufey and an enemy of The Avengers.

Adopted by Odin and Frigga at the end of the Asgardians' war with the Jotuns, Loki is treated as a prince of Asgard and was never informed of his true heritage throughout his youth. Loki is smaller and thinner, and has a darker hair colour while paler in complexion than the Asgardians. Throughout their childhood Loki spent much of his time trying to prove himself as Thor's equal, while studying magical arts rather than physical prowess.

Unlike his adoptive brother, Loki is not an impulsive man, quite the opposite; thoughtful, manipulating, farseeing, he's the perfect tactician. Loki is mischievous by nature, always eager to prove himself. Being physically weak, he developed a sharp intellect and an acute mind to overcome his handicap among the Asgardians. He's pitiless and obstinate, ready to destroy everything in his path for his goals. Brilliant and smart, he's an incredible foe for a society mostly based on brutish combatants.

By The Avengers, Loki had become more dangerous than ever before. He was more cunning and devious, although he was still deeply conflicted. During his encounters with Thor, he showed that he still cared for his adoptive brother and father, but also still resented them: Odin for lying to him about his heritage and Thor for overshadowing him all his life ("I remember a shadow, living in the shade of your greatness.") He may also have developed delusions of grandeur, as he believed that Thor tossed him into the wormhole left by the destruction of the Bifrost, when in truth he allowed himself to fall in after Odin didn't approve of what he had done. He had also become even more ruthless than ever before, if not sadistic. This is evident when he smirked while striking the device in the curator's eye socket, and when he threatened Black Widow that he will make Barton torture her in ways she fears, awaken him to see her dead, and then kill him as well.

Being a misshapen Frost Giant, Loki possesses some of the characteristics of his kind, including resistance to extreme cold and to his brethrens's frost powers. He also possesses superhuman physical abilities, such as strength, stamina, speed and reflexes, but to an extent closer or even equal to the Asgardians. He's a skilled magician, specializing in the art of illusion, and can create mirages of himself, make himself invisible to anyone, included the omniscient Heimdall, and can even control the minds of lesser beings like humans. Loki proves some skills in combat while battling the Frost Giants on Jotunheim and wielding Odin's spear, Gungnir.

Superhuman Strength: Loki possesses a formidable strength as a result of his Jotun lineage that is comparable to his Asgardian contemporaries. He kicks a S H I E L D agent several yards into a wall so hard that it broke his bones and killed him, and throws Tony Stark across a room and through a window with only one arm. To him, humans are very light and can be lifted and thrown like dolls. He was able to overpower Captain America with ease. His strength also extends his ability to leap distances far in excess of human capability. However, his superhuman strength is far inferior to that of Thor,Odin,or the Hulk.

Superhuman Durability: As a Jotun, Loki has a resilient body with a tolerance for trauma that's similar to the Asgardians. Of particular note is his pronounced tolerance for cold. High caliber bullets will simply bounce off him. Loki has taken multiple blows from Captain America and a blow from Captain America's shield which failed to injure him. He also withstood a full blast from a weapon based on the Destroyer, multiple blasts from Iron Man's repulsors, and a small explosive arrow from Hawkeye, and in each case he got out with only minor damage. While he was dazed and badly injured by the Hulk, he was far from dead and managed to recover enough to stand up not long afterwards and only had minor cuts and bruises that healed in hours.

Superhuman Longevity: Loki has the capacity to live for thousands of years like the average Asgardian. Loki was a baby at the end of the last great war between the Asgardians and the Jotuns over a thousand years ago.

Superhuman Speed/Agility: Loki is fast enough to catch Hawkeye's arrows in mid-flight, inches away from his face. He also used his speed in his fight against Captain America, during which he easily gained the upper hand, at one point even smashing Cap's shield into the ground with a swing of his sceptre, as it was flying at him when Captain America threw the shield at him. When his plot to destroy the Aether was revealed, he managed to kill all the Dark Elves that surrounded him with nothing more than his dagger.

Sorcery: Loki is a master of magic. His magic comes from Frigga who decided to share it with him. He can create illusions, including copies of himself, and can influence people with his mind. He was also able to exert a more potent hypnotic control when using his sceptre directly on people who were trying to stop him. He can also conceal himself and others from sight. Loki can summon objects out of thin air, as seen when he summons the Casket of Ancient Winters and uses it against Heimdall, freezing him solid. He can also alter his appearance and attire at will, even to take the form of anyone else. His mastery of illusions was such that he could trick Malekith into thinking that he betrayed Thor, and that he could fake his own death while still appearing to have sacrificed himself to destroy Kurse. At realizing the death of Frigga, he clenched his fists and a green shock wave emerged from him and blasted away everything in his Asgardian prison cell and cause a second-long adn small tremor in his cell that flickered all the light in it.

Cold Manipulation: As a Frost Giant, Loki can generate mystic cold, as seen when he froze the lightning in the Bifrost Bridge to jam its functions.

Loki has shown that being a "god" of a different world, he is able to understand and eventually utilize Earth and other alien technology to an excellent degree, such as using the eye device on the scientist and learning to use the control console that controls the cage.

Expert Combatant: Loki has extensive combat training that allowed him to fight off and kill several Jotuns in Jotunheim, easily kill several S.H.I.E.L.D. operatives, easily overpower Captain America, hold his own against Thor briefly, and kill several Dark Elves with nothing more than a dagger.

In battle, Loki uses throwing knives to injure his enemies, though he is also proficient with a spear or a dagger.
While he was the king of Asgard, Loki used magic artifacts like Odin's spear, Gungnir, which can project mystical blasts of energy, and control the Destroyer or the Casket of Ancient Winters.
Loki used a special staff that was exceedingly powerful. He was able to use it as a means of energy projection of a powerful blue laser blast which was powerful enough to kill several S.H.I.E.L.D. agents. Loki also used the staff to put people under his mind control and even stabbed Agent Coulson through his torse and heart with the blade.
Loki was also known to use a dagger extensively in combat, to the point where it's one of his preferred weapons.

Also in the comics Loki turned into a girl.

I think that is all the facts you need to know about Loki Laufeyson the God of Mischief.
