Loki Laufeyson

Loki is the main antagonist in the 2012 Marvel Studios film The Avengers. He is played by Tom Hiddleston.

Biography
Loki is the adopted son of Odin and Frigga, as well as adopted brother of Thor. He is seen as an envious and a violent man who will stop at nothing to banish Thor and kill him. Loki first appeared in Thor when Thor was supposed to be crowned. As a prank to 'ruin his brother's big day', Loki allowed several Frost Giants to steal the Casket of Ancient Winters. Thor, upset by the turn of events, leds Loki, Sif and the Warriors Three to Jotunheim where a battles begins. During the fight, Loki is touched by a Jotun and does not react to the Frost Giant's freezing touch. The fight is interrupted when Odin comes and takes them back to Asgard. Odin, disappointed for Thor's actions, banishes Thor powerless to Earth until he became worthy once more by picking up Mjolnir.

Loki then appears in the armory and questions Odin about his true heritage. Odin reveals that Loki is actually a Frost Giant that he found during a war. Before loki can find out the full truth, Odin falls into the 'Odin-sleep'. While Odin is asleep, Loki becomes king of Asgard and forbids Thor from returning. Loki then travels to Earth and tells Thor that he is banished to keep Asgard from going to war with Jotunheim and that Odin is dead.

When Loki discovers that Sif and the Warriors Three have gone to earth to retrieve Thor, he sends the Destroyer to make sure they do not return. Loki then brings in Jotuns to kill Odin, but later betrays them. After Thor regains Mjolnir and defeats the Destroyer, Thor then returns to deal with Loki. Loki likewise orchestrated an invasion by the Frost Giants, although he quelled the invasion and killed their leader in an attempt to gain Odin's trust. When Thor comes back to face Loki in Asgard and he tries to fight him as he wants to stop Loki from destroying Jotunheim. Thor then breaks the Rainbow Bridge that binds Asgard to other worlds. As Thor and Loki cling to the broken bridge, Odin wakes from the Odin-sleep and saves them. Loki then tells Odin that he could have been king and that destroying Jotunheim was for the best. Odin replys by saying no and Loki lets go, falling into a dark abyss.

Loki is seen again after the credits, alive and well, who influences Dr. Erik Selvig to research the newly found Tesseract.

Loki also appeared in the 2012 movie The Avengers. This time he returned to Earth and his one mission and job to do. Steal the tessaract cube and take over the world. Loki has received a staff from the Chitari. Using his staff he takes control over Dr. Erik Selving, Agent Clint Barton (aka Hawkeye), along with several others. He is, however, threatened by the Chitauri that he will end up suffering an immense, horrific, and (literally) unavoidable punishment should he either fail or backstab them before the invasion. Under Loki's command, Selving is able to find a way to harness the power of the Terresact, Loki went to Germany to provide a distraction for Barton to retrieve the necessary items. While Barton receives the items needed for Selvig, Loki battles Captain America before surrendering to the newly arrived Iron Man. The two heroes, along with Black Widow, take Loki into custody when Thor arrives and takes his brother. Thor attempts to reason with Loki and take him back to Asgard when he's interrupted by Iron Man.

They soon take Loki into S.H.I.E.L.D headquarters, where he antagonizes Nick Fury. He is soon liberated by Barton and his oter followers, but not before dropping Thor out of the Helicarrier and killing Agent Phil Coulson. It was also revealed that Loki deliberately allowed himself to be captured so he could ensure destruction of the group form within, and also intended to have Bruce Banner go Hulk and thus use it as the means to his freedom. Loki then opens the portal to allow the Chitari to wreak havoc on New York City from Stark Tower. All the superheroes, Iron Man, The Hulk, Black Widow, Captain America, Hawkeye, and Thor assemble to stop him as given by Fury's commands. The Hulk and Loki face off but, Loki is beaten when Hulk smashes him to the ground. The Chitari are finally stopped when Iron Man flies a nuke into space, almost killing him in the process.The heroes find him and they arrest him, placing a magic collar on him cannot talk. Thor then takes Loki and the Terressact back to Asgard.

Loki will also make a small cameo apparence in the movie Thor 2 which is set to come out in 2013.

Personality
Loki is the God of Mischief and an expert liar. Though Loki tries to take over Asgard and Earth, all Loki really wants is the approval of his father and brother. He is a smart and intelligent man and he will stop at nothing to fulfill his quest. While he may seem like a nice guy, Loki believes to be destined for a 'glorious purpose' whether it be ruling Asgard or Earth. Loki is usually considered as a liar and trickster, but only wanted to an equal to Thor. Therefore Loki has every feeling and he does communicate with some people even though he's a powerful man and a pretty hard boss to defeat.

Powers
Despite being a member of the Frost Giants, Loki possesses similar attributes to those possessed by the Asgardians. After his rebirth, he lost most of his powers.

Superhuman Strength: Loki, without the aid of anything, through his own biology, possesses superhuman strength that is substantially superior to that of an average Asgardian female or male. In fact, Loki is currently stronger now than he was while male. He possesses sufficient physical strength to lift up to 50 tons. It is possible, however, that he can further increase his strength through mystical enchantment on a temporary basis. While as a male Loki was still superhumanly strong as an average Asgardian male, he was strong enough to lift 30 tons, however his strength could be increased through mystical enchantment also.

Supernatural Dense Tissue: Like all Asgardians, Loki's bodily tissues have roughly 3 times the density of the same tissues in a human being. While he has the looks and physical proportions of a much smaller person, the increased density of his body actually makes him several hundred pounds heavier than he appears. This increased density also contributes to his superhuman strength to a limited degree.

Superhuman Durability: The tissues of Loki's body are superhumanly durable and are roughly equal to those possessed by the average Asgardian male. However, at times, Loki had imbued himself with magical abilities that enable him to withstand injuries that would prove fatal to another Asgardian if hit. He is able to withstand high caliber bullets, falls from great heights, powerful impact forces, exposure to temperature extremes and powerful energy blasts without being injured. He has proved in past to be durable enough to withstand energy blast's from Mandarin's Rings and several blows from Spider-man without so much to even blink.

Regenerative Healing Factor: Like all Asgardians, Loki, although he is inhumanly durable, at least by human standards, can still obtain injury, also like all Asgardians, his metabolism enables him to rapidly regenerate damaged tissue much faster and more extensively than a human being. However, through the use of his sorcery, Loki's ability to heal himself is far above that of other Asgardians. His magical energies are so imbued into his body that he can reattach severed limbs and, while still a male, even reattached his own head at least once.

Superhuman Stamina: Loki's Frost Giant metabolism grants him superhuman levels of physical stamina in practically all activities. He can exert himself at peak capacity for about 24 hours before fatigue begins to impair him. However, much like his physical strength and durability, Loki can temporarily augment his stamina through magical means.

Superhuman Longevity: Like all Asgardians, Loki ages at a far slower rate than humans. However, unlike some other god pantheons like the Olympians, who stop aging completely at a certain point, Loki isn't fully immune to aging. Although he has recently been "reborn", he still has his memories of his previous life. While he is several millenia old, at least, he has the appearance and vitality of a young Asgardian man in his physical prime. Loki is immune to the effects of all known Earthly diseases and infections.

Sorcery: Loki has the ability to generate and control a great quantity of mystical abilities for a variety of purposes, of which can be used to further enhance or augment his physical diagram, like his speed, strength, and stamina, but only temporarily. His magical abilities are equal to Karnilla, the most skilled sorceress of the Nine Realms. Being a telekinetic, Loki can influence the movement of objects and people with his mind, and as such, this power proves to be devastating and chaotic in nature. His known abilities include the ability to fire powerful beams of concussive force, generate highly durable force fields, bestow superhuman attributes to living beings or inanimate objects, or teleport himself or others across dimensions. He can also bring inanimate objects to life, or mystically imbue objects or beings with specific but temporary powers. He has, for example, augmented the might of human criminals as the Cobra and Sandu. These magical effects remain only for as long as he maintains the spell that created them. Loki has also once cursed Deadpool with an indestructible Tom Cruise's face, which proved to be powerful enough to withstand being run over by a train and direct contact with a nuclear rod without receiving a single scratch. He has also once used his magic to turn Invisible Woman's psionic shields against herself. Loki’s power has been said by the Silver Surfer during their early encounters as sufficient to “decimate a planet", and according to Dormammu, Loki’s magic nearly rivals that of his own.
 * Psionics: Loki has demonstrated powerful psionic capabilities, the full limits of which aren't known. He has demonstrated the ability to project his thoughts telepathically across great distances as well as potent hypnotic capabilities. He is able to communicate with beings telepathically, though his ability to do so is greater with beings that serve him.
 * Shape-shifting: Like a number of gods or goddesses, Loki possesses highly developed shape-shifting capabilities. He is able to adopt almost any form imaginable whether it be animals, other humanoid beings, or even inanimate objects. The thought has been raised that his current form is merely a shape Loki has decided to remain in. Despite this well-known ability of Loki's, he has commented to himself, as he struggled to escape from Dormammu's mystic cage, that this is his "most soul-draining" power, apparently meaning it is more taxing than his other magical abilities. He has become such animals such as a snake, eagle, mouse and bee, gaining the basic natural abilities inherent in each form. While he can take on the likeness of another god, giant or human, he will not necessarily gain the special physical or mental powers of the being he imitates. Loki can also transform external objects into other forms and substances by magic; for instance, he has turned clouds into dragons and even changed cars into ice cream.

Abilities
Intelligence: Loki has a genius level intellect and possesses a great deal of knowledge of the mystic arts, gifted with mastery superior to that of a Sorcerer Supreme's. He is also extremely cunning and skilled, an expert battle strategist, and highly skilled and charismatic manipulator, which is evident by the ease how Loki repeatedly succeeded to regain the trust of his fellow asgardians, despite his numerous crimes.

Master Combatant: Loki is a formidable combatant in his own right, particularly as a swordsman or in the use of his various energy manipulative powers in combat situations, enough to hold his own against Thor on numerous occasions and beat the Disir into (literal) submission.

Weakness
Magic Limitations: Loki's powers are believed to at least be slightly weaker on Midgard than on Asgard, as his birth was not of Gaea, and even Odin's magic was on the wane on Earth. Also, while apparently possessing some extrasensory abilities that resemble psionic powers. Loki can not directly read the minds of other beings, nor can he control their actions.

Superiority Inferiority Complex: Loki's ambition has proven to be his greatest flaw, as his passionate hatred of Thor, lust for power, and his tendency to alienate himself through his ignoble actions greatly impedes his ability to bring his well laid plans to fruition. Also, as noticed by Apocalypse, Loki has poor understanding of human nature, which leads him to severely underestimate his mortals (earthly) opponent's, resulting into humiliating defeat.
