Alors que les Avengers et leurs alliés ont continué de protéger le monde face à des menaces bien trop grandes pour être combattues par un héros seul, un nouveau danger est venu de l'espace : Thanos. Despote craint dans tout l'univers, Thanos a pour objectif de recueillir les six Pierres d'Infinité, des artefacts parmi les plus puissants de l'univers, et de les utiliser afin d’imposer sa volonté sur toute la réalité. Tous les combats que les Avengers ont menés culminent dans cette bataille, qui décidera du destin de la Terre et du reste de l'univers, et qui impliquera tous les héros déjà connus, dont les Gardiens de la Galaxie.
The Asgardian Loki encounters the Other, the leader of an extraterrestrial race known as the Chitauri. In exchange for retrieving the Tesseract, a powerful energy source of unknown potential, the Other promises Loki an army with which he can subjugate Earth. Nick Fury, director of the espionage agency S.H.I.E.L.D., and his lieutenant Agent Maria Hill arrive at a remote research facility during an evacuation, where physicist Dr. Erik Selvig is leading a research team experimenting on the Tesseract. Agent Phil Coulson explains that the object has begun radiating an unusual form of energy. The Tesseract suddenly activates and opens a wormhole, allowing Loki to reach Earth. Loki takes the Tesseract and uses his scepter to enslave Selvig and a couple of agents, including Clint Barton, to aid him in his getaway.
In the Eastern European country of Sokovia, the Avengers – Tony Stark, Steve Rogers, Thor, Bruce Banner (Hulk), Natasha Romanoff, and Clint Barton – raid a Hydra outpost led by Baron Wolfgang von Strucker, who has been experimenting on humans using the scepter previously wielded by Loki. They encounter two of Strucker's experiments – twins Pietro, who has superhuman speed, and Wanda Maximoff, who can manipulate minds and project energy – and apprehend Strucker, while Stark retrieves Loki's scepter.
Après les évènements de Sokovie et l'affrontement avec Ultron, Thor est parti à la recherche des Pierres d'Infinité. Deux ans après, sans résultat, on le retrouve emprisonné dans le monde de Surtur (Muspellheim). Il se libère et vainc le démon enflammé, après que ce dernier lui a appris qu'Asgard est sans défense en l'absence du « Père de Toute Chose », Odin. Thor lui arrache sa couronne que le démon comptait unir avec l'Éternelle Flamme afin de provoquer le Ragnarök, la destruction d’Asgard.
Scientist David Banner introduces the idea of creating super soldiers by introducing modified DNA sequences extracted from various animals to strengthen the human cellular response, making them effectively impervious to any weaponized agent, but General Thaddeus Ross denies him permission to use human subjects. Banner subsequently conducts the experiments on himself. After the birth of his son Bruce, he finds that his son may have inherited the effects and seeks a cure, but is stopped in the process. Bruce remembers nothing of the incident after a traumatic event, and has been raised by the Krenzlers. Years later, Bruce is a geneticist working with his ex-girlfriend Betty Ross, within the Berkeley Biotechnology Institute on nanomed research. The pair hope to achieve instantenous cell repair by using low level Gamma radiation exposure to activate the nanomeds once they are introduced into a living organism. During routine maintenance of their appropriated Gammaspectrometer, a circuit shorts and triggers the experiment's program sequence. Unable to prevent the machine from firing, Bruce throws himself in front of his colleague to shield him and is exposed to incredibly toxic levels of Gamma.
At Culver University in Virginia, General Thunderbolt Ross meets with Dr. Bruce Banner, the colleague and boyfriend of his daughter Betty, regarding an experiment that Ross claims is meant to make humans immune to gamma radiation. The experiment — part of a World War II era "super soldier" program that Ross hopes to recreate — fails, and the exposure to gamma radiation causes Banner to transform into the Hulk for brief periods of time, whenever his heart rate rises above 200. The Hulk destroys the lab and injures or kills the people inside. Banner becomes a fugitive from the U.S. military and Ross in particular, who wants to weaponize the Hulk process.
T'Challa, the Prince of Wakanda, returns home to find his kingdom is being attacked by the alien Chitauri. Herr Kleiser, the alien shape-shifter who battled Captain America during World War II, kills T' Challa's father and seeks Wakanda's store of vibranium, the metal the Chitauri use to manufacture their ships and weapons. After becoming king and assuming the alias of the Black Panther, T' Challa seeks out Captain America. General Nick Fury of S.H.I.E.L.D. orders the Avengers to assemble, with the exception of Thor (who foresees a future in which the Avengers die in battle, which his father Odin confirms) and the Hulk who, as Bruce Banner, is interrogated and bullied in a cell.
The Hulk's allies the Avengers decide he is too dangerous to remain on Earth, so they put him in a shuttle and attempt to send him to a peaceful world. He awakens on board the shuttle before it arrives at its intended destination. When he goes into a fit of rage, breaking his restraints, he also causes enough damage to veer it off course, resulting in a crash on the planet Sakaar. Imperial guards appear and attach an obedience disk to the Hulk, allowing them to communicate. The Hulk is imprisoned with Hiroim, Korg, Miek, Elloe Kaifi, Lavin Skee, an Android, and a few hived natives.
In the last days of World War II in Europe, Captain America, due to enhancement by a "Super-Soldier Serum", prevents the Nazis from launching an intercontinental missile. They are also soon revealed to be shape-shifting extraterrestrials led by one acting as SS officer Herr Kleiser. The exploding missile knocks the Captain out and he falls into the icy waters of the North Atlantic, presumed dead. 60 years later, Captain America is found and revived by a S.H.I.E.L.D. team led by General Nick Fury. Bruce Banner and Betty Ross lead a team of scientists working to recreate the Super-Soldier Serum in order to try to stop the real power that backed the Nazis - the alien Chitauri. Banner thinks the Super-Soldier Serum is the key to him controlling the Hulk, and he secretly uses his blood to try to create a cure, instead of using candidates that had been selected for the rebirth procedure. As Captain America reunites with his old friend James "Bucky" Barnes, he also learns that his past lover Gail Richards, is married to him and has lived a happy life. Despite being happy for his friends and everyone that he loved, Captain America still feels lost in the present world he is in, unable to find happiness like he wants to.
Captain America est un super soldat qui combat les nazis, mais un missile le met dans un état catatonique. Nick Fury et son équipe du SHIELD sont rejoints par d'autres super-héros pour combattre des aliens dit "Chitauri"...
Two Hydra scientists add the Hulk's gamma energy to Tony Stark’s arc reactor technology, creating the energy creature Zzzax. The Hulk and Iron Man team up to take them down. They also fight the Abomination, and a fleet of Mandroids.
Ce documentaire est consacré à l'histoire des super-héros américains depuis leur apparition dans les années 1930. Il présente de nombreux dessins issus des comics originaux, des extraits de leurs adaptations en films et dessins animés, ainsi que des entretiens avec des auteurs importants du genre.
Hulk vs. Wolverine
In the prologue Wolverine wakes up dazed and confused in a crater in the mountains. As he tries to recall how he got there he is confronted by the Hulk, jogging his memory. Wolverine was sent by Department H to track down a beast called "the Hulk" by the US Military, which has been rampaging across the Canadian Wilderness. In the ruins of Elkford, British Columbia Wolverine picks up its scent. After a few hours tracking the creature in the wilderness, Wolverine finds Dr. Bruce Banner. He questions him but starts to violently interrogate him after realizing that he had the same scent as the creature. Ignoring numerous warnings, Wolverine continues the interrogation until Banner transforms into the Hulk and sends him flying, and crashing into a crater.
Two years after the episode "A Minor Problem", Dr. David Banner has been gainfully employed at the Joshua-Lambert Research Institute (as David Bannion) where he and a team of scientists are putting the final touches on a Gamma Transponder, which he intends to use to cure him of his ability to turn into the Hulk. He has not changed into the Hulk for two years since he met a young widow, Maggie Shaw, with whom he is romantically involved. By chance, he is recognized by a former student of his, Donald Blake. Blake claims that, on an expedition in the Norwegian mountains, he found an enchanted hammer containing the soul of Thor, an immortal Norse warrior banished by Odin to Earth to earn worthiness into Valhalla. Thor is reluctantly compelled to serve Blake, who is unnerved by this. Banner does not believe him, so Blake summons Thor into Banner's laboratory. Thor damages equipment and angers Banner until he turns into the Hulk, who easily fights him off and leaves.
