Attack on Titan Episode List


Commander Erwin has returned home with his troops. The crowd marvels at Levi and the others. Before the invasion on Trost District by the Titans, Commander Irwin and his group had ventured out during their expedition to seek knowledge that will support human advance against the Titans. Every excursion into Titan territory has cost 30% of the troops. When a Titan munches on a soldier's torso, the soldier stabs the Titan's face and tells the Titan that Captain Levi will exterminate them all.

Suddenly, Levi soars across the roofs and slices the Titan's neck, killing it. Petra arrives with reinforcements. Levi instructs Petra to tend to the wounded and orders the others to support the right flank while he takes the left flank by himself. Elsewhere, Hanji opens her arms to a Titan and dodges its attack with glee. She swings around and kills it easily. Meanwhile, Levi kills two Titans single handily without breaking a sweat. Levi arrives to see one dying soldier. The soldier asks Levi if he was useful at all. Levi grasps his dying comrade's hand and confirms that he had left him strength. He promises him that he will obliterate the Titans. Petra informs him that he has passed away in peace. Commander Irwin arrives and tells Levi that they are withdrawing. He informs him that the Titans are heading north and thinks this situation is similar to an incident five years ago. He states that the wall has fallen.

Meanwhile, Eren finds himself in the belly of the Titan, surrounded by the dismembered corpses of his fellow soldiers. He wonders why this is happening, despite all their training. He hears a woman calling out to her mother, causing him to remember his mother. He watches as woman's head sinks slowly into the liquid. Eren vows to wipe out all the Titans. Suddenly, a giant hand shoots out of the Titan's mouth. Eren reemerges as a Titan as he bursts out from the Titan's back. He walks towards the crawling Titan and smashes its face. Eren wakes up from his dream and sees Armin and Mikasa. The other soldiers are pointing their blades at Eren. Meanwhile, Connie explains what had happened to Ymir and Krista. Jean and the others are speechless after Eren's transformation. Hannes speaks with some team members about the wall that is lined by Titans. His team member asks Hannes about the three children he had saved. Hannes states that the three are alive and well.

Back at base, Eren wonders why the men are looking at him. The captain states that the others had saw him emerged from a Titan. He threatens to kill Eren for being a scourge to humanity. Mikasa steps up to defend Eren while Armin tries to talk everyone out. Eren answers that he is human. When Mikasa grabs Eren, a key falls out. Eren recalls his father's secret in the basement. He recalls his father giving him an injection. Eren quickly grabs Armin and Mikasa and bites his thumb. He blocks the cannon ball with his Titan hand. When the smoke clears, everyone looks in horror at a deformed Titan, with Mikasa and Armin underneath the rib cage.
