==History==
===HYDRA Society===
====Foundation====
Thousands of years ago, a rogue Kree faction created the Inhumans on prehistoric Earth. The ruling Kree hierarchy, deeming the creation of the Inhumans a mistake, conceived the Monolith as a means of wiping them out by transporting them across space to another planet.Agents of S.H.I.E.L.D.: 2.20: Scars One day, an Inhuman was born so powerful, that others banished him to the other planet. However, the Inhuman's followers, believing him to be destined to rule the world, formed a secret society with the sole purpose to bring their leader back to Earth.
Over the centuries, the society grew and evolved, taking many different shapes, being called by many different names. Eventually, the society came in possession of the Monolith, and started sending men through the portal, hoping to save or at least serve their leader on the other side. But none of them ever came back. As its symbols changed, the society became known as HYDRA.Agents of S.H.I.E.L.D.: 3.08: Many Heads, One Tale 
====Centuries of Attempts====
The story of HYDRA's attempts to bring their leader back to Earth was eventually spread through the world, influencing groups obsessed with death and ritualistic killings, becoming intertwined with the origin of pagan devil myths. Their initial symbol was one for a sacrificial ram.
In 1839 at Gloucestershire, England, a group of HYDRA members assembled in a castle to have a lottery. He who grabbed the white stone from the bag was to enter the room housing the Monolith. Lord Manzini grabbed the white stone and was sent into the room with a few weapons and some equipment. The portal opened and swallowed Manzini who was never seen again. Apparently, he was but one of many to be sent as a sacrifice. HYDRA's best minds were employed to understand how the Monolith functions, but they never gathered enough data to bring anyone back.
Eventually, HYDRA's scientists managed to construct a machine that could create powerful vibrations. In the late 1800s, they put the Monolith in a hole in the floor and activated the machine, turning the Monolith into its liquid form, creating a stable portal. For some reason, the castle and the machine were abandoned.Agents of S.H.I.E.L.D.: 3.02: Purpose in the Machine Smaller pieces were cut off from the Monolith and given for safekeeping to various leaders of HYDRA.
===HYDRA-Abteilung===
====Planting the Roots among the Nazis====
When the Nazis came to power in Germany, a secret HYDRA member Johann Schmidt attempted to join the special weapons division of the Nazi Sturmabteilung (SA) led by Ernst Kaufmann so he could work on developing advanced weapons for the German Army. However, he was violently rejected and instead joined Heinrich Himmler's Schutzstaffel (SS). In June 1934, during the , 
Kaufmann and his entire unit were eliminated by Schmidt's SS troops. Only one man was spared, Doctor Arnim Zola. Schmidt took over Kaufmann's weapons program and formed his own research division, naming it HYDRA-Abteilung.Captain America: First Vengeance, Volume 2 The new unit was formed with the official approval of the Nazi Führer, Adolf Hitler.
HYDRA-Abteilung was named after the mythological creature and used its original phrase: "cut off one head, two more will take its place". It was soon charged with science experiments and deep investigation of the occult. Due to contributions from Arnim Zola, HYDRA developed several extremely advanced weapons.Captain America: The First Avenger
When the started in 1936, the leaders of the Third Reich decided to support the led by . HYDRA was among the German units sent by Adolf Hitler to assist the Nationalists on the battlefield.
In April 1937, HYDRA's tanks and soldiers equipped with powerful exo-skeleton battle suits destroyed the city of Guernica. At the time, it was believed the German air force, the Luftwaffe, was responsible for the destruction of the city. However, the footage of the slaughter was smuggled out of Germany by the British agent Margaret Carter and handed over to the US military in January 1940.Captain America: First Vengeance, Volume 5
====The Beginning of World War II====
In 1939, World War II broke out. HYDRA's leader Johann Schmidt actively participated in the Nazi conquest of Europe. Though the United States of America were not yet involved in the war, Schmidt knew that was only temporary. In 1940, HYDRA assassins attempted to kill the American industrialist Howard Stark, but with the help of Colonel Chester Phillips, Stark was able to defeat the attackers, and decided to join the Strategic Scientific Reserve.Captain America: First Vengeance, Volume 3
That November, at Castle Kaufmann in the , Schmidt injected himself with Abraham Erskine's Super Soldier Serum. He expected to become the superior man, but the unstable serum disfigured his face and turned him into a super strong megalomaniac villain. Erskine escaped with the help of Agent Peggy Carter, Colonel Phillips, and Stark.
Adolf Hitler gave Schmidt a military base in the Alps, which he turned into a headquarters of HYDRA. Over time, HYDRA members became more loyal to Schmidt than the Third Reich.
Immediately after the start of the war, HYDRA began building several factories across the Nazi-occupied Europe. By 1942, they had factories in Germany, Austria, Belgium, France, Greece, Poland, Italy, and Czechoslovakia. They used captured Allied soldiers to work in factories. They even had a U-boat base somewhere on the Mediterranean.Captain America & Thor: Avengers!
====The Rise of HYDRA====
In March 1942, HYDRA stormed a castle in Tønsberg, Norway where the mystical object known as the Tesseract was buried 531 years ago by Odin. Schmidt saw to it that the Tesseract would be used to its full potential by Arnim Zola. Zola's outlandish designs of robotic power armor, massive vehicles and energy weapons and armor could find a functional use thanks to the Tesseract's power, and with the most advanced technology in the world, HYDRA began their conquest that counted Berlin in its targets.
In the meantime, a HYDRA officer, General Werner Reinhardt, was sent to search for other mysterious artifacts.Agents of S.H.I.E.L.D.: 2.01: Shadows Reinhardt's team was able to discover the blue-skinned extraterrestrial corpse in some unspecified location, possibly in the deserts of North Africa.The insignia of the German Afrika Korps on the boxes carried by HYDRA soldiers in Shadows implies the corpse was found somewhere in North Africa before the surrender of the Army Group Africa on 13 May 1943. The corpse was soon stored in HYDRA Research Facility Number 4 in Austria.
Soon, HYDRA's goals would be challenged by America's own super-soldier, Captain America. In November 1943, Rogers attacked the HYDRA factory in Austria, and managed to free all Allied soldiers who were imprisoned there. This was the first direct conflict between Rogers and Schmidt, who activated self destruct mode and escaped in the experimental plane. Aided by his best friend, Bucky Barnes and the Howling Commandos, Captain America began a massive assault on HYDRA forces across the Axis lines, destroying numerous bases.
During the first months of 1944, when the German air force launched the last "Blitz", Schmidt sent a group of HYDRA agents to London to steal some blueprints from the Strategic Scientific Reserve. The agents were successful, but they were soon discovered and chased by Captain America who managed to capture all of them.The Avengers: The Avengers Initiative
In May 1944, the HYDRA submarine Leviathan destroyed an Allied merchant freighter in the Mediterranean with HYDRA's thunder lance torpedo, but Captain America, who was traveling on the sunken ship, boarded the submarine and captured it. Cap and Commandos infiltrated the HYDRA U-base where they discovered that the mysterious "Hydra serum" merged the entire base's staff into one octopus-like creature. Cap took the creature to Howard Stark to separate it back into individual men.
In April 1944, HYDRA took possession of an old castle on an island in the Nazi-occupied Danish Straits. Schmidt was interested in that castle because of an ancient Viking runestone that was hidden there. The same month, Captain Rogers and the Howling Commandos invaded the castle. Schmidt attempted to destroy them through his "vita batteries" but they survived.
In the meantime, General Reinhardt managed to capture a group of people from China who had found the Obelisk, an object which could turn people into stone. When he showed the artifact to his leader, Schmidt said that the Obelisk may hold the answer to death itself. The Obelisk was soon stored in Reinhardt's fortress in Austria where he used it to experiment on his prisoners.
By the beginning of 1945, Arnim Zola had to be moved to another HYDRA facility. However, his train was attacked by the Howling Commandos and he was captured. He was later moved to London where he was interrogated by Colonel Chester Phillips.
====Defeat====
Despite the loss of Doctor Zola, in May 1945 Schmidt was ready to launch the offensive that would change the face of the planet. The same day on which Schmidt intended to launch the attack, the base was infiltrated by Captain America, who was captured and brought before Schmidt himself. However, before Schmidt could kill his nemesis, the base was attacked by the Howling Commandos and the U.S. Army detachment led by Colonel Chester Phillips. Outnumbered, Schmidt's men were eventually defeated, but not before Schmidt flew away in his Tesseract-powered bomber, the Valkyrie. He intended to nuke all bigger cities in America.
Captain America managed to board the plane and came face to face with Schmidt. When it became clear that Rogers was gaining the upper hand in the fight, Schmidt attempted to use the power of the Tesseract with his bare hands. This only resulted in a beam of light, similar in design to the Bifrost Bridge, which caused Schmidt to disappear, and forcing Rogers to put the bomber plane down in the freezing waters below, freezing himself solid and causing the Tesseract to be lost to the seas.
Immediately after Schmidt's disappearance, Werner Reinhardt had the Obelisk moved from his Austrian fortress to a more secure location, a research facility. A month later, he and his lieutenant attempted to empty the facility so they could escape with the artifacts and continue HYDRA's work. At that moment, Reinhardt's unit was the last active HYDRA cell. However, despite their hurry, the base was discovered and attacked by the US Army detachment led by the Strategic Scientific Reserve team composed of Peggy Carter, Dum Dum Dugan and Jim Morita. After a short fight, the garrison of the base surrendered. All HYDRA soldiers were arrested and the artifacts, including the Obelisk, were confiscated. However, before he was taken away, Reinhardt promised to Agent Carter that HYDRA would rise again.
===Rebirth===
====After The War====
In the aftermath of World War II, the United States started Operation Paperclip, a program used to recruit the scientists of Nazi Germany for employment by the United States and deny their scientific expertise and knowledge to the Soviet Union. As part of the operation, Zola was recruited into S.H.I.E.L.D., the newly formed peacekeeping organization.Captain America: The Winter Soldier Agent Carter then interrogated Reinhardt about his experiments with the Obelisk, and the girl he experimented on. Carter then had Reinhardt sent to the Rat to serve his life imprisonment.Agents of S.H.I.E.L.D.: 2.08: The Things We Bury
Many other former Nazis and HYDRA scientists escaped to South America, hoping to hide from justice. Several of them were employed by the government of Peru to make the new Tesseract-powered weapon. The government wanted to use the weapon against the rebels, but due to the instability of the Tesseract energy, the weapon ended up stuck in the undiscovered Incan temple.Agents of S.H.I.E.L.D.: 1.02: 0-8-4
Various HYDRA operatives who escaped justice after World War II infiltrated S.H.I.E.L.D. shortly after the agency was formed, working secretly in their ranks. Over the next decades, led by Zola, HYDRA worked from the shadows, directing their agents to complete the tasks that were assigned.
Shortly after the war, Arnim Zola found Sergeant James Barnes, Captain America's war-time partner who was presumed deceased after falling to an icy death from Zola's train in 1945. Zola and other scientists took Barnes to one of HYDRA's secret bases, presumably in the territory held by the Soviet Union, where they replaced his lost left arm with the new cybernetic limb. They brainwashed him, and since he was already injected with another version of the Super Soldier Serum, they turned him into the new fist of HYDRA. Though he was wearing the communist red star on his new limb, Barnes never fought for the Soviet ideals, instead becoming HYDRA's best assassin known as the Winter Soldier. Over the next decades, he did much on creating chaos in the world, assassinating those who could pose a threat to HYDRA's goals, and spending time between missions in cryogenic sleep.
====Toward the New World Order====
HYDRA's power eventually grew so much that they were able to orchestrate many Cold War events during the 1960s and 1970, including the , the rise to power of in Libya, the , and the .
With S.H.I.E.L.D.'s resources, Zola managed to build an entire computer system which his mind was uploaded into as an artificially intelligent user interface. Though Zola's body died in 1972, his mind continued to live in cyberspace, from which he was able to provide easy passage into the agency for more HYDRA sleeper agents.
By the early 1980s, HYDRA managed to infiltrate the Soviet power structures, establishing a secret laboratory in East Berlin. They continued their memory suppression experiments from World War II with the goal to create an army of brainwashed soldiers who would follow every order. However, the laboratory was infiltrated by Hank Pym, a S.H.I.E.L.D. agent who used his size-changing Ant-Man Suit to ruin the laboratory, destroy the Memory Suppressing Machine, free the prisoner and knock down all the guards.Ant-Man Prelude, Volume 2
In 1989, undersecretary Alexander Pierce, an HYDRA sleeper agent, granted Werner Reinhardt a medical parole and made sure there were no records of him after this. Reinhardt was then taken back to his fortress where a group village elders from the Hunan province, which included the woman he experimented on, were brought in. Seeing that she had not aged a day, Reinhardt then performed surgery on her to find out why the Obelisk did not kill her and why she did not age. Although he did not find the reason behind Obelisk's reason for sparing her, Reinhardt was able to use her DNA to regress his body back to a younger age. Reinhardt then took the name "Daniel Whitehall".
HYDRA also oversaw Project Deathlok in 1990, using the turncoat S.H.I.E.L.D. agent John Garrett as their first test subject. He was the first Deathlok. However, only the cybernetic components worked, and the organs were severely affected, leading Garrett to look for a solution to perfect Deathlok and to prevent his slow-coming death. Agents of S.H.I.E.L.D.: 1.21: Ragtag
In 1991, Howard and Maria Stark were killed in an automobile "accident" secretly arranged by HYDRA on Long Island, this caused Tony Stark to inherit Stark Industries and become, at age 21, the youngest CEO of a Fortune 500 company.Iron Man
====Facing the Other Worlds====
In the meantime, Gideon Malick, a wealthy industrialist and one of HYDRA's heads, was working on Project Distant Star Return, hoping to bring HYDRA's ancient Inhuman leader back to Earth. Using his connections, he orchestrated the passage of the Monolith to NASA, with the hope that their technicians could send people on the other side. In 2001, a four men team was sent through the portal, never to return.Agents of S.H.I.E.L.D.: 3.05: 4,722 Hours Eventually, Malick became a member of the World Security Council.
The HYDRA weapons and technology captured by the Strategic Scientific Reserve during the war were studied by S.H.I.E.L.D.. In 2011, S.H.I.E.L.D. started a program called "Phase 2", which involved reactivating the HYDRA weapons with the Tesseract for use against super-powered or other-worldly forces. Several cases of HYDRA weapons were stored aboard the Helicarrier. However, the weapons weren't needed, because when the Chitauri led by Loki invaded New York City, the aliens were defeated by the Avengers. During the battle, Malick ordered Nick Fury to nuke New York, which Fury refused, and later criticized Fury for allowing Thor to take the Tesseract and Loki to Asgard.The Avengers
In the aftermath of the Battle of New York, HYDRA's leader Baron Wolfgang von Strucker approached Mark Smith, the S.H.I.E.L.D. agent who worked on the Scepter with the scientist Nicholas Cooper, and offered him to join HYDRA. Dissatisfied with the way S.H.I.E.L.D. was led, Smith accepted the Baron's offer, killed Cooper, and stole the Scepter for HYDRA. Thanks to Smith's betrayal, HYDRA's scientists also got their hands on dozens of Chitauri Guns. Later, HYDRA built a research facility in the Eastern European country of Sokovia. Over the next two years, a team of scientists led by Doctor List and Baron von Strucker managed to use the Scepter to power the Chitauri Guns and HYDRA's own technology. They also conducted experiments on human volunteers, including the twins Wanda and Pietro Maximoff.Avengers: Age of Ultron Prelude - This Scepter'd Isle
====The "Clairvoyant"====
Following the Battle of New York, one of HYDRA's agents within S.H.I.E.L.D., John Garrett, going under the alias, the Clairvoyant,Agents of S.H.I.E.L.D.: 1.17: Turn, Turn, Turn, recruited and funded the Centipede Project to provide them with super-soldiers and to help keep himself from dying. Garrett also recruited the boxer Carl Creel, by faking his termination off S.H.I.E.L.D.'s Index.Agents of S.H.I.E.L.D.: Shadows One of the first was Mike Peterson.Agents of S.H.I.E.L.D.: 1.01: Pilot In his Clairvoyant persona, Garrett made people like Ian QuinnAgents of S.H.I.E.L.D.: 1.14: T.A.H.I.T.I. and RainaAgents of S.H.I.E.L.D.: 1.11: The Magical Place believe that he could see everything such as what the President dreams about. Garrett also had another sleeper agent, Grant WardAgents of S.H.I.E.L.D.: 1.18: Providence, recruited by Phil Coulson for his team. Ward's mission was to find out about Coulson's revival. Garrett then had Coulson capturedAgents of S.H.I.E.L.D.: 1.10: The Bridge and interrogated for three days to find the secrets behind his revival in Tahiti. Garrett then ordered Quinn to shoot Skye.Agents of S.H.I.E.L.D.: 1.13: T.R.A.C.K.S. He then made sure that he would be the one to take Quinn in, and to have Coulson lead him to where he was revived. After getting inside, unbeknownst to Coulson and Leo Fitz, he took a few of the drugs and hid them in his vest before the place was destroyed. He then had Mike Peterson, going under the codename "Deathlok", turned into a cybernetic super soldier.Agents of S.H.I.E.L.D.: 1.16: End of the Beginning
===HYDRA Uprising===
====Project Insight====
Two years after the Battle of New York, S.H.I.E.L.D. was much better armed than before, so it could easily repel any attack from other worlds. With new funds granted by the World Security Council, Nick Fury started Project Insight, an operation which involved three heavily armed Helicarriers that were designed to proactively strike out against potential threats before they actually happened.
However, HYDRA's agents used this opportunity to take control of the project. With Arnim Zola's special algorithm that could calculate who could be a threat to HYDRA in the future, the leader of HYDRA's S.H.I.E.L.D. branch, Alexander Pierce, intended to wipe out 20 million people from the face of the Earth.
====The End of S.H.I.E.L.D.====
In 2014, the HYDRA infiltration of S.H.I.E.L.D. was finally exposed when corrupted senior official Alexander Pierce attempted to activate Project Insight early. Steve Rogers and Natasha Romanoff learned about the infiltration when they entered the secret bunker hidden beneath Camp Lehigh, which was housing Arnim Zola's mind, still alive on dozens of old computers. Though the camp was destroyed with the missile, Rogers and Romanoff survived the explosion. A day later, with the help of Sam Wilson they kidnapped Jasper Sitwell, but he was killed by HYDRA's best assassin, the Winter Soldier. The trio was captured by the STRIKE team, but they managed to escape with the help of Maria Hill.
Alexander Pierce demanded a mission report from the Winter Soldier after the failed assassination attempt on Captain America. However he had become erratic and aggressive due to flashbacks to his past. As Pierce believed that he could become a threat if left like this, he ordered that the Winter Soldier's mind be wiped. The procedure caused the Winter Soldier great physical pain.
A day later, Rogers, Romanoff, Wilson, and Hill infiltrated the Triskelion, publicly revealing HYDRA's continued existence. Alexander Pierce and his men then captured all the members of the World Security Council, but they were freed by Romanoff. When HYDRA's agent Brock Rumlow launched the Insight Helicarriers, Romanoff, Rogers, Hill, and S.H.I.E.L.D. Director Nick Fury managed to reprogram the Helicarriers to target each other. The battle left the Triskelion in shambles and resulted in the deaths of many HYDRA agents, including Pierce. Rumlow survived the battle, but he was badly burned, and the Winter Soldier abandoned HYDRA.
====The Age of Miracles====
Despite the failure of Project Insight, HYDRA continued with its operations. At the same time when S.H.I.E.L.D. fell, at the research facility in Sokovia, HYDRA's scientists were still conducting experiments on the Scepter, eventually learning that its power was much greater than they originally thought. Many civilian volunteers exposed to the power of the Scepter died in horrifying deaths. However, the twin brother and sister Wanda and Pietro Maximoff survived the experiments, gaining super powers.Captain America: The Winter Soldier Mid-credits Scene 
Shortly after the Battle at the Triskelion, Dr. List came to Wolfgang von Strucker, afraid that the authorities would find their location, but von Strucker assured him that wasn't the case. As they walked toward the cells of Wanda and Pietro Maximoff, von Strucker told the doctor that the age of miracles was upon them.
====New Battles====
In order to finish off S.H.I.E.L.D., HYDRA sent out an activation signal to all sleeper agents to target Level 8 S.H.I.E.L.D. agents and seize power. During the Battle at the Hub, John Garrett broke his cover and attempted to eliminate Agent Phil Coulson and several members of his team, but he was stopped and later arrested by Agent Victoria Hand. Garrett and the remaining HYDRA moles in the Hub were taken into prison.
Meanwhile, HYDRA's sleeper agents in other S.H.I.E.L.D. bases were also activated. Several facilities fell into HYDRA's hands, including the S.H.I.E.L.D. Academy, the Treehouse, and S.H.I.E.L.D.'s East African Headquarters. HYDRA's operatives also attempted to take control of the Cube, but they were outnumbered by the loyal S.H.I.E.L.D. agents who managed to repel the attack. A fierce battle was fought for the control of the aircraft carrier Iliad, but HYDRA's moles were ultimately defeated.Agents of S.H.I.E.L.D.: 2.15: One Door Closes
John Garrett, after escaping Agent Victoria Hand's custody with the aid of fellow HYDRA agent Grant Ward, continued to work on the Centipede Project at the HYDRA base in Havana, Cuba.
Garrett then raided the Fridge, stealing many items such as the Peruvian 0-8-4, the Berserker Staff, and the Gravitonium. They also freed a number of prisoners. Ultimately, his branch of HYDRA was defeated by the combined efforts of Phil Coulson, his team, and Nick Fury, with their prisoners also freed and most of the stolen items recovered.Agents of S.H.I.E.L.D.: 1.22: Beginning of the End
===Out of the Shadows===
====The Winter Hunt====
Despite Colonel Glenn Talbot's massive manhunt for S.H.I.E.L.D. and HYDRA agents and bases, HYDRA continued its plans for world domination by retreating to the shadows. Despite its existence being publicly known, HYDRA was still determined as ever to conquer the world by any means necessary. Their plans could go much easier as they now heavily outnumbered S.H.I.E.L.D. in men, bases, and resources.Agents of S.H.I.E.L.D.: Heavy is the Head
====Whitehall's Campaign====
HYDRA agent, Sunil Bakshi, at the behest of Werner Reinhardt, now known as Doctor Daniel Whitehall, sent one of their assassins, Carl Creel to retrieve an 0-8-4. However, the Obelisk was then taken by Raina and Creel was then captured by S.H.I.E.L.D. and turned over to General Talbot.Agents of S.H.I.E.L.D.: Heavy is the Head
Following that, HYDRA recruited former S.H.I.E.L.D. agent Jemma Simmons. In reality, however, Simmons was actually undercover for S.H.I.E.L.D. under orders from Director Coulson himself. HYDRA's next move was to locate Donnie Gill, a former S.H.I.E.L.D. Academy student who displayed freezing powers. They found him in Casablanca, Morocco, but when the two agents approached him, he froze them both, killing them. A team led by Sunil Bakshi and Jemma Simmons was sent to capture him. When Gill encountered them on HYDRA's cargo ship Maribel del Mar, they managed to activate his mind control trigger. A S.H.I.E.L.D. team suddenly appeared and Bakshi ordered Gill to destroy them. However, Gill was shot by Skye and he fell off the ship. Bakshi then ordered his men to retreat.Agents of S.H.I.E.L.D.: Making Friends and Influencing People
In the meantime, HYDRA managed to capture a former S.H.I.E.L.D. operative Agent 33. Using the Faustus method, Whitehall brainwashed the agent to his cause. HYDRA also continued to investigate the Words of Creation that Garret had been carving. Bakshi, disguised as General Talbot, and Agent 33 were sent to Miami, Florida to retrieve a 500 year old painting that had the writing. However, in the ensuing battle, they lost the painting to Director Coulson and Agent Melinda May.Agents of S.H.I.E.L.D.: 2.04: Face My Enemy
====Weaponizing the Obelisk====
HYDRA, using skin samples from an Obelisk victim, created a toxin and used it on a Naval anti-HYDRA unit, killing some of them. HYDRA then had its security chief, Barbara Morse, hunt for a traitor in its midst. At first, Kenneth Turgeon was thought to be the traitor, but the traitor was revealed to be Jemma Simmons. Fortunately for Simmons, Morse revealed herself to be a S.H.I.E.L.D. agent and the two escaped. Whitehall and Bakshi then had the lab dismantled and relocated.
However, Whitehall then met The Doctor, who gave him back the Obelisk, and offered to give him and HYDRA its secrets in exchange for killing Coulson.Agents of S.H.I.E.L.D.: 2.05: A Hen in the Wolf House Whitehall, using deceased HYDRA scientist Vincent Beckers's weapons designs, had Toshiro Mori weaponize the Obelisk, now known as the Diviner, incorporating its power into Splinter Bombs.Agents of S.H.I.E.L.D.: 2.06: A Fractured House
Whitehall then had Marcus Scarlotti and his team attack the United Nations posing as S.H.I.E.L.D. agents, killing several delegates and wounding General Talbot. Following the attack, Belgian Foreign Affairs Minister Julien Beckers offered his country as a safe haven for S.H.I.E.L.D. agents. However, it was revealed that he was Vincent Beckers' grandson and loyal to HYDRA, setting a trap for S.H.I.E.L.D. agents. Beckers then had Scarlotti kill S.H.I.E.L.D. agent Noelle Walters and her team. However, Beckers, Scarlotti and his team were apprehended by S.H.I.E.L.D. agent Melinda May's and General Talbot's teams.
Sunil Bakshi took two operatives with him to meet Grant Ward in Goldbrix Tavern, a Boston establishment run by a HYDRA operative. Bakshi stated that he was surprised to hear from Ward because it was believed that he had died. Ward, knowing that Wolfgang von Strucker was operating overseas, asked if he could meet Bakshi's superior, but he was told that Whitehall was too busy for a meet-and-greet. Ward tempted Bakshi by saying that he could get him a face-to-face with Phil Coulson. However, Ward then killed the bartender and the two other operatives. He knocked Bakshi unconscious and left him tied to a chair with tape on his mouth with the words "To Coulson". Bakshi was later found by a S.H.I.E.L.D. team led by Melinda May.Agents of S.H.I.E.L.D.: 2.07: The Writing on the Wall
====Search for the City====
Meanwhile, Whitehall was upset that his scientists gave him information about the Diviner that he had known since 1945. When The Doctor was brought in at gunpoint, Whitehall explained to him that tensions were high since the capture of Bakshi. The Doctor asked to hear all Whitehall knew about the Diviner so he could edit the story appropriately. The Doctor informed him that there was a temple in a city that the Diviner screened for worthy candidates; the unworthy were petrified. He then requested a team to find that city.
Though originally hesitant, Whitehall allowed The Doctor to take a team to Laura Creek, Australia; there was a satellite relaying station in that location that was easy to infiltrate. During the mission, they ambushed Phil Coulson's team and Antoine Triplett was fatally shot. The Doctor offered to help him live so that he could meet Coulson personally.
The Doctor told Coulson that he was surprised that he was searching for the city since Whitehall did not know about it until he told him. Ultimately, Coulson let him escape in order to finish saving Triplett. When The Doctor returned to Whitehall, he was introduced to Grant Ward, who has rejoined HYDRA.
Meanwhile, Bakshi, in a show of loyalty to HYDRA and Whitehall, used a cyanide pill lodged in his cheekbone to stop the interrogation of Bobbi Morse when she revealed that S.H.I.E.L.D. was researching the continued survival of Werner Reinhardt into the 21st century.
====Battle for the Kree City====
A team of HYDRA agents led by Agent 33 was sent to Vancouver, Canada, where HYDRA finally managed to find Raina. However, when Raina saw and realized who Agent 33 is, she started running away from her. Though she temporarily escaped, Agent 33 located her at the S.H.I.E.L.D. Vancouver safehouse, where she got into conflict with Skye. She was eventually knocked down by Skye and Lance Hunter. A few minutes later, a group of HYDRA agents saw a S.H.I.E.L.D. team taking Raina into a van and escaping. Agent 33 informed Whitehall about Raina's escape and he told her that he would send his best man to take care of the situation.Agents of S.H.I.E.L.D.: 2.09: Ye Who Enter Here
Later, four of HYDRA's Quinjets followed the S.H.I.E.L.D. plane which was carrying Raina. Grant Ward, who was commanding HYDRA's forces, threatened to shoot the plane unless S.H.I.E.L.D. hands over Raina. The S.H.I.E.L.D. agents onboard the plane had to comply, but Ward also forced Skye to come with him, promising that he would spare the lives of her colleagues. When Ward's Quinjet flew away, Whitehall ordered the remaining aircraft to destroy the enemy plane. The Quinjets launched missiles at the plane, which was hidden in the cloud, seemingly destroying it.Agents of S.H.I.E.L.D.: 2.10: What They Become
Meanwhile, thanks to the attack on the Laura Creek Station, HYDRA managed to discover the location of the ancient Kree City which was built thousands of years earlier. The city was hidden under the city of San Juan in Puerto Rico. Whitehall and Agent 33 immediately traveled to San Juan, where HYDRA quietly occupied the Ponce de León Theater, with their agents drilling a tunnel to the Kree City. Once Ward, Raina, Skye, and The Doctor came there, Whitehall forced Skye to touch the Obelisk. She survived the touch, and killed one HYDRA agent with it. Ward then aimed his pistol at Whitehall's men, while The Doctor killed one agent with his scalpel. But the mutiny was short lived, and they were all taken into custody.
When the tunnel was finished, a group of S.H.I.E.L.D. agents infiltrated the theater. Raina went into the Kree City, while Whitehall and his men attempted to deal with the intruders. However, as The Doctor encountered Whitehall alone in the corridor and prepared to kill him, Whitehall was shot in the back by Phil Coulson. Agent 33 then arrived, shooting at them, and discovered Whitehall's dead body. Without Whitehall she did not know what to do, so she returned to the wounded Ward, who convinced her to help him to leave the scene.

====Cutting Off the Heads====
With Whitehall dead, his seat in the HYDRA Council remained empty, and the remaining heads of HYDRA discussed who could take Whitehall's place. The gathered leaders were Dr. List, the Sheikh, the Baroness, the Banker and Octavian Bloom. Dr. List, acting on the order of Baron von Strucker, proposed Sunil Bakshi. Other leaders replied that he was probably captured by S.H.I.E.L.D. and therefore dead, if he did his duty. Dr. List told them to stop underestimating S.H.I.E.L.D., and that the person that destroys S.H.I.E.L.D. will win Whitehall's position, while he personally would take a look at Whitehall's research of arcane artifacts.Agents of S.H.I.E.L.D.: 2.11: Aftershocks
Meanwhile, Sunil Bakshi managed to escape from S.H.I.E.L.D. and went to Octavian Bloom's house. Convinced that other leaders of HYDRA wanted to eliminate them, he and Bloom contacted Doctor List, who assured them that he and Baron von Strucker were not involved in any attacks on them. Afraid that they could be the next target, Bakshi convinced Bloom to simply kill the other three leaders. Using the Splinter Bomb and other tools that weaponized the effect of the Obelisk, Bloom's men killed the Banker, the Sheikh, and the Baroness. However, Bloom's house was infiltrated by Bakshi's "rescuer", actually a S.H.I.E.L.D. agent Lance Hunter, and his colleague Bobbi Morse. The two intruders killed Bloom and recaptured Bakshi, revealing that his escape was a ruse concocted by S.H.I.E.L.D.'s director Phil Coulson to lead the organization to HYDRA's leadership. Some time later, Bakshi was kidnapped from General Glenn Talbot's base by Agent 33 and Grant Ward who decided to brainwash him with the Faustus method.Agents of S.H.I.E.L.D.: 2.14: Love in the Time of HYDRA
====The New Threat====
A new threat to HYDRA's plans soon arose. The Avengers were officially reassembled, and they started tracking down HYDRA's operations. When Dr. Jensen in her secret lab in Port Sudan, Sudan managed to reverse engineer the obtained Chitauri tech, she informed her colleagues in Khartoum to come help her. The call was intercepted by Black Widow, and the Avengers quickly flew in their Quinjet to the location of Jensen's lab. Though HYDRA managed to shoot down the Quinjet, the Avengers fiercely attacked HYDRA's soldiers. Despite their tanks, guns, and numerical superiority, HYDRA soldiers decided to retreat. However, Dr. Jensen took the power gauntlets from one fallen soldier and attacked the Avengers with heavy energy blasts. Unfortunately for her, Hawkeye sneaked up behind her and destroyed her weapon with one of his explosive arrows.Avengers: Operation HYDRA
====The Hunt for the Enhanced====
Meanwhile, Doctor List became interested in powered people. List's soldiers started hunting them and managed to capture several of them, and List used the opportunity to experiment on them.Agents of S.H.I.E.L.D.: 2.16: Afterlife One of his victims was Ethan Johnston, but he couldn't find the Quantum Entanglements he was searching for, the traces of a man who had the ability to teleport from one place to another. One day, List was called by Sunil Bakshi, and they had a meeting on List's plane. With Bakshi was Mike Peterson, and Bakshi offered him to List, saying that he could become a great asset to HYDRA. List agreed to take Bakshi to Baron von Strucker's base in Eastern Europe.Agents of S.H.I.E.L.D.: 2.18: The Frenemy of My Enemy
During the journey, the plane made a stop in San Francisco, and Bakshi, Peterson, and numerous HYDRA soldiers entered one abandoned building. Once they were inside, they faced an unknown man, the Doctor who previously worked with Daniel Whitehall, and several S.H.I.E.L.D. agents. Peterson managed to knock down the unknown intruder, but Bakshi then ordered his men to take Peterson down. In the end, HYDRA won the battle, taking the prisoner with them.
The both prisoners were taken to List's base in the Arctic, where the doctor continued his experiments. He also informed Baron von Strucker about the development of the situation, who was very pleased with the news. Suddenly, a plane approached the base. Realising the intruders were S.H.I.E.L.D. agents, List ordered his men to shoot them out of the sky. The plane was destroyed, but the intruders managed to survive the crash and infiltrated the base. In the ensuing battle, all HYDRA agents in the base were killed, but Dr. List managed to escape and eventually rejoined Baron von Strucker in Sokovia.Agents of S.H.I.E.L.D.: 2.19: The Dirty Half Dozen
====Disaster in Sokovia====
Unfortunately for HYDRA, S.H.I.E.L.D. learned about the exact location of their Sokovian base from their facility in the Arctic and passed that information to Maria Hill, who gave it to the Avengers. The Sokovian base was attacked, and though HYDRA soldiers managed to slow down the Avengers, their tanks, armors and advanced weaponry were no match for the strength of the attackers. The base was ultimately captured, Dr. List was killed by Iron Man, and Baron von Strucker was captured by Captain America. The twins Wanda and Pietro Maximoff, though they briefly fought the Avengers, eventually abandoned the site of the battle.Avengers: Age of Ultron
The main laboratory inside the base was discovered by Iron Man who took the Scepter and had it transported to the Avengers Tower. Baron von Strucker and the remaining HYDRA soldiers were handed over to NATO. Baron von Strucker was later killed in his prison cell by the insane robot Ultron.
===HYDRA Strikes Back===
====Raising the Inhuman Army====
Despite the fall of most of HYDRA's cells and the abrupt end of many of HYDRA's operations, Gideon Malick remained in his public position undetected, still incredibly powerful. Eventually he became an advisor to President Matthew Ellis and used his connections to continue with Project Distant Star Return. He even expanded the project, manipulating the US Government to authorize the creation of the Advanced Threat Containment Unit, an agency that would replace S.H.I.E.L.D. and collect and study the newly transformed Inhumans. Overseeing the ATCU's science division, Malick aimed to create an Inhuman Army for HYDRA's first leader to command when he returns from his exile on Maveth. Malick's men in the ATCU gave the fish oil pills contaminated by the impure Terrigen Crystals to many people so they could create as many Inhumans as they could.
====Dealings with Darren Cross====
A team led by Mitchell Carson, one of HYDRA's top sleeper agents in the original S.H.I.E.L.D., came in contact with the corrupt businessman Darren Cross, the leader of Cross Technologies. Cross offered to sell HYDRA Hank Pym's Pym particle technology, the same technology that Carson failed to get his hands on in 1989 when Pym abandoned S.H.I.E.L.D. With the Yellowjacket Suit, Cross intended to reassert HYDRA's dominance, but his efforts were squashed by Scott Lang, the second Ant-Man. However, during the chaos, Carson did escape with a vial of Cross' modified Pym Particles.Ant-Man
====Grant Ward's Campaign====
=====New Members=====
Devoid of leadership, HYDRA operatives were reluctant when Grant Ward decided that he would take the reins of leadership. Ward was forced to physically engage Kebo to show his control.Agents of S.H.I.E.L.D.: 2.22: S.O.S. Part Two
For months, the bank accounts and financial transactions of HYDRA known by S.H.I.E.L.D. had no activity. Lance Hunter did research to find any activity but found nothing.Agents of S.H.I.E.L.D.: 3.01: Laws of Nature
Meanwhile, Ward recruited new members for his own HYDRA cell, continuing his private war against Phil Coulson's S.H.I.E.L.D. Ward made it known that he was to be addressed as Director, mirroring Coulson's position with S.H.I.E.L.D. He also decided to clean HYDRA from weak and corrupt members who cared only about the money. He kidnapped and eventually convinced Werner von Strucker, the son of the late Baron Wolfgang von Strucker, to join HYDRA so they could rebuild the organization and make it stronger than ever.Agents of S.H.I.E.L.D.: 3.02: Purpose in the Machine To ensure that HYDRA's ranks were filled only with the strongest and the toughest men and women, Ward and Kebo began organizing fights for the new volunteers, accepting as new members only the winners.Agents of S.H.I.E.L.D.: 3.03: A Wanted (Inhu)man
=====Attack on the Director=====
One of the winners in the fight club was Richy who killed Spud during his fight. Richy worked under Kebo's orders and brought to HYDRA a large weapons cache and even agreed to join a mission with Kebo. When he was brought to Ward's base, he opened fire on Ward and his men, revealing himself as Lance Hunter, a S.H.I.E.L.D. agent on a revenge mission to kill Ward. A firefight started between Ward's men and Hunter and another S.H.I.E.L.D. agent, Melinda May soon appeared on the scene. Ward ordered Kebo to call Werner von Strucker and order him to get closer to May's ex-husband Andrew Garner so he could kill him and threaten May. Despite the video, Hunter continued advancing on Ward and Kebo. The pair managed to escape by jumping through the window and running onto a truck, but not before Hunter managed to fire a shot which wounded Ward in the shoulder. When Ward did not cancel his order, von Strucker attempted to continue with his mission,Agents of S.H.I.E.L.D.: 3.04: Devils You Know but failed due to unexpected circumstances.
=====Tensions between the Heads=====
While Ward, Kebo, and their men moved to another base, Werner von Strucker went to Gideon Malick, the head of another HYDRA cell and the only modern HYDRA leader that all other heads feared. Von Strucker informed Malick about Ward's actions and he was not pleased with the news. To make the situation clear, Malick called Ward and offered him redemption for his mistakes, such as making von Strucker a pawn on the chessboard before schedule, but Ward arrogantly replied that he did not need redemption. However, knowing that von Strucker was now a damaged good that couldn't be left to run around knowing HYDRA's secrets, Malick gave his location to Ward to prevent internal fights within HYDRA's ranks and ensure Ward's cooperation in HYDRA's resurgence.
Sent by Ward, Kebo and two of his men caught up with von Strucker in Lisbon and captured him. However, the torture session was interrupted by the arrival of two S.H.I.E.L.D. agents, Melinda May and Bobbi Morse, who were also looking for von Strucker. In the ensuing fight, Kebo was electrocuted to death in a swimming pool and his men were beaten by the intruders. Before he went into a coma, von Strucker told May that he saw Andrew Garner transforming into "that thing".Agents of S.H.I.E.L.D.: 3.06: Among Us Hide...
Though Ward's cell lost three men, the mission was a partial success. Shortly after, Ward and Malick organized a meeting to discuss joint operations against S.H.I.E.L.D. Ward revealed to Malick that he was planning the assassination of Phil Coulson, both for revenge and the destruction of S.H.I.E.L.D.Agents of S.H.I.E.L.D.: 3.07: Chaos Theory

*According to artist Ryan Meinerding, it took a long time to design the HYDRA logo.
