Attack on titan

Gernes: action, drama, fantasy, shounen, super power, thriller

Season 1:

Several hundred years ago, humans were nearly exterminated by giants. Giants are typically several stories tall, seem to have no intelligence, devour human beings and, worst of all, seem to do it for the pleasure rather than as a food source. A small percentage of humanity survived by walling themselves in a city protected by extremely high walls, even taller than the biggest of giants.

Flash forward to the present and the city has not seen a giant in over 100 years. Teenage boy Eren and his foster sister Mikasa witness something horrific as the city walls are destroyed by a super giant that appears out of thin air. As the smaller giants flood the city, the two kids watch in horror as their mother is eaten alive. Eren vows that he will murder every single giant and take revenge for all of mankind.

Season 2:

For centuries, humanity has been hunted by giant, mysterious predators known as the Titans. Three mighty walls—Wall Maria, Rose, and Sheena—provided peace and protection for humanity for over a hundred years. That peace, however, was shattered when the Colossus Titan and Armored Titan appeared and destroyed the outermost wall, Wall Maria. Forced to retreat behind Wall Rose, humanity waited with bated breath for the Titans to reappear and destroy their safe haven once more.In Shingeki no Kyojin Season 2, Eren Yeager and others of the 104th Training Corps have just begun to become full members of the Survey Corps. As they ready themselves to face the Titans once again, their preparations are interrupted by the invasion of Wall Rose—but all is not as it seems as more mysteries are unraveled. As the Survey Corps races to save the wall, they uncover more about the invading Titans and the dark secrets of their own members.

Season 3: part 1

Still threatened by the "Titans" that rob them of their freedom, mankind remains caged inside the two remaining walls. Efforts to eradicate these monsters continue; however, threats arise not only from the Titans beyond the walls, but from the humans within them as well. After being rescued from the Colossal and Armored Titans, Eren Yaeger devotes himself to improving his Titan form. Krista Lenz struggles to accept the loss of her friend, Captain Levi chooses Eren and his friends to form his new personal squad, and Commander Erwin Smith recovers from his injuries. All seems well for the soldiers, until the government suddenly demands custody of Eren and Krista. The Survey Corps' recent successes have drawn attention, and a familiar face from Levi's past is sent to collect the wanted soldiers. Sought after by the government, Levi and his new squad must evade their adversaries in hopes of keeping Eren and Krista safe. In Shingeki no Kyojin Season 3, Eren and his fellow soldiers are not only fighting for their survival against the terrifying Titans, but also against the terror of a far more conniving foe: humans.

Seeking to restore humanity's diminishing hope, the Survey Corps embark on a mission to retake Wall Maria, where the battle against the merciless "Titans" takes the stage once again. Returning to the tattered Shiganshina District that was once his home, Eren Yeager and the Corps find the town oddly unoccupied by Titans. Even after the outer gate is plugged, they strangely encounter no opposition. The mission progresses smoothly until Armin Arlert, highly suspicious of the enemy's absence, discovers distressing signs of a potential scheme against them. Shingeki no Kyojin Season 3 Part 2 follows Eren as he vows to take back everything that was once his. Alongside him, the Survey Corps strive—through countless sacrifices—to carve a path towards victory and uncover the secrets locked away in the Yeager family's basement.
