Shinji Ikari

It's an independent military weapons organization that wants to eliminate giant beings known as "angels."

They are "aliens" who seek to destroy humans over a territorial dispute, as they believe the Earth belongs to them.

Thanks to ancient writings, it is known that Lilith and Adam are two types of aliens who were created to give life to the planets.

Lilith created small beings with the capacity for reasoning.

They possess an important element called the "Spear of Longinus." Lilith and Adam carried this spear when they arrived on Earth; it is a very powerful weapon, and thanks to it their creations live. If Lilith and Adam were on the same planet, the Spears of Longinus would activate and attack the other; the survivor would have the right to inhabit the planet.

Like Lilith, Adam was created by other aliens to populate other planets.

Adam created enormous beings with abstract forms and "little reasoning."

The first known impact was a long time ago. Adam was the first to arrive on Earth and had already created his children; however, Lilith arrived shortly after and upon landing broke Adam's Spear of Longinus, making it impossible for him to fight. Therefore, Lilith was able to create her own form of life; that was the first impact.

The Evas are giant robots that allow young people (14 years old) to pilot them to fight the Angels. The pilots are placed in a capsule, inserted between the head and the base of the spine; this simulates a spinal cord. The capsule is then filled with fluid, simulating cerebrospinal fluid, thus forming the connection between the robot and the pilot.

Each Eva has various weapons to fight against the angels; it also has a shield called the "AT Shield" that blocks the angels' attacks.

There are three very important phases of the pilot connection – Eva, the first connection, which causes the pilot to only feel pain without physical damage; the complete connection, where the damage to the robot is exactly the same as that received by the pilot, meaning that if the robot loses an eye in this connection phase, the pilot will also lose an eye; and finally, there is the "Berserker" mode, which is basically letting the robot act on its own.

The Evas have a very impactful trait for choosing their pilots; a loved one of the pilot must die touching the unit to make the soul of that loved one protect them in their battles.

Nerv researchers managed to find Adam's body and, unaware of the impending catastrophe, they removed the Lance of Longinus from Adam, freeing him from any restraint. After being freed, there was a massive explosion that left Misato Katsuragi as the sole survivor; this was the Second Impact.

Because Tokyo has been destroyed on several occasions, it opted to be a city that could retract its buildings so that, when fighting the angels, the damage would be much less.
