In the year 2015, half of humanity is dead. 14-year-old Shinji Ikari is summoned to the fortress city of Tokyo-3 by his estranged father, only to be thrown into the cockpit of a massive biomechanical weapon, Evangelion Unit-01, to fight a monstrous entity known as an Angel.
Shinji awakens in a hospital with fragmented memories of his first battle. Through a horrifying flashback, the terrifying truth of the Evangelion is revealed as Unit-01 goes berserk, regenerating its own flesh and savagely tearing the Angel apart.
Shinji tries to adjust to normal school life while living with his commanding officer, Misato Katsuragi. His secret identity as an Eva pilot is exposed, earning him the wrath of his classmate Toji Suzuhara, whose sister was injured during the Angel attack.
Overwhelmed by the crushing pressure and isolation of his duty, Shinji runs away from NERV. He wanders the desolate, lonely outskirts of Tokyo-3, forcing him to confront whether he pilots the Eva to save humanity or simply to earn his father's approval.
Shinji tries to understand Rei Ayanami, the enigmatic, emotionless pilot of Unit-00. He discovers her disturbing lack of self-preservation and her unusually close, almost unnatural bond with his father, Gendo.
The geometric, heavily armed Angel Ramiel drills into NERV headquarters. Shinji and Rei are forced to execute Operation Yashima, a massive, high-stakes sniper mission that requires the entire electrical grid of Japan to power a single, desperate shot.
To secure a massive budget, a private defense contractor unveils the Jet Alone, a nuclear-powered, unmanned alternative to the Evangelions. When the machine goes rogue and threatens a nuclear meltdown, Misato must risk her life to manually shut it down.
Misato and Shinji travel to a UN Pacific fleet escorting Eva Unit-02 to Japan. They are introduced to the fiery, arrogant prodigy Asuka Langley Soryu. When an aquatic Angel attacks the fleet, Asuka forces Shinji into her cockpit for a chaotic underwater battle.
The Angel Israfel splits into two identical entities, effortlessly defeating Shinji and Asuka. To beat it, the two fiercely independent pilots are forced to undergo humiliating, synchronized dance training to execute a perfectly timed, dual-strike combination.
A dormant Angel is discovered deep within the magma of an active volcano. Asuka is sent down in a specialized heat-resistant suit to capture it alive, but the mission goes critically wrong when the Angel rapidly matures and attacks her in the crushing depths.
A massive, unexplained blackout completely disables Tokyo-3 and NERV headquarters. As a spider-like Angel begins dissolving the base's armor, the three pilots must manually navigate the labyrinthine air ducts to reach their Evas without power.
The massive Angel Sahaquiel threatens to drop from orbit like a biological nuke. Misato orchestrates a desperate, three-pronged sprint to catch the falling Angel with the Evas' bare hands, reflecting on her own tragic past during the Second Impact.
A microscopic, rapidly evolving Angel infiltrates NERV's MAGI supercomputer system. Dr. Ritsuko Akagi must engage in a frantic, high-speed hacking war to stop the Angel from initiating a self-destruct sequence, revealing the dark history of the MAGI's creator—her mother.
SEELE convenes to review NERV's progress, leading into a mid-season recap. In the second half, a bizarre, deeply unsettling cross-synchronization experiment causes Unit-00 to go violently berserk, targeting Rei and Gendo.
Shinji and Gendo visit Yui Ikari's grave. Misato, Ritsuko, and Kaji attend a wedding, exposing the complex, painful romantic entanglements between the adults. Kaji's espionage work begins to unravel NERV's deepest, darkest secrets.
Shinji's overconfidence leads him directly into the shadow of the Angel Leliel, trapping Unit-01 in a bizarre, mathematically impossible pocket dimension. As life support fails, Shinji experiences a terrifying psychological breakdown before the Eva erupts from the Angel in a shower of blood.
NERV's American branch is annihilated in a mysterious accident involving Unit-04. Unit-03 is shipped to Japan, and the Marduk Institute shockingly selects Shinji's classmate, Toji Suzuhara, as the Fourth Child to pilot it.
Unit-03 is hijacked by an Angel during its activation test. Refusing to harm the trapped pilot inside, Shinji disobeys direct orders. Gendo coldly overrides Shinji's controls, forcing Unit-01's Dummy Plug to brutally and methodically dismember Unit-03 while Shinji watches in horror.
Traumatized by what he was forced to do to Toji, Shinji quits NERV. The devastating Angel Zeruel effortlessly breaches the GeoFront, crippling Asuka and Rei. Shinji returns at the last second, leading to a desperate fight where Unit-01 achieves a terrifying, god-like synchronization.
Having achieved a 400% sync ratio, Shinji's physical body has dissolved into the LCL inside the entry plug. Over the course of a month, Ritsuko frantically attempts to salvage his soul while Shinji floats in a surreal, Freudian dreamscape confronting his deepest fears.
The dark, bloody history of NERV, SEELE, and the Katsuragi Expedition is revealed through a series of fragmented flashbacks. Fuyutsuki is kidnapped and interrogated, while Kaji makes a fatal decision to uncover the absolute truth behind the Evangelions.
Asuka's synchronization rates plummet as her psychological trauma catches up with her. The Angel Arael attacks from orbit, using a telepathic beam to forcefully violate Asuka's mind, dragging her repressed childhood horrors to the surface and breaking her spirit completely.
The Angel Armisael merges with Unit-00, attempting to fuse with Rei. In a deeply uncharacteristic move, Rei sacrifices herself to destroy the Angel and save Shinji. The horrifying truth behind the Evangelions and Rei's true nature is finally laid bare to a shattered Misato.
A boy named Kaworu Nagisa arrives as the Fifth Child. He offers Shinji the unconditional love and acceptance he has always craved. The tragedy reaches its peak when Kaworu is revealed to be the final Angel, forcing Shinji to execute the only person who truly loved him.
The Human Instrumentality Project begins. The narrative completely abandons the physical world, plunging into a deeply abstract, avant-garde psychological examination of Shinji, Asuka, Misato, and Rei as their souls are forcefully merged into a single collective consciousness.
In the final, highly controversial conclusion to the series, Shinji confronts the core of his self-hatred within the void of Instrumentality. Through a profound existential realization, he chooses to reject the collective and accept the pain of individual existence. Congratulations.
