Eren Yeager broke the shonen hero mold in Attack on Titan

Published on June 26, 2026 | Translated from Spanish

In 2018, Attack on Titan executed a twist that shook the foundations of shonen anime: its protagonist, Eren Yeager, became the villain. Traditionally, these heroes always ended up being good, but Eren, upon discovering the future, chose a destructive path called the Rumbling. This radical change demonstrated that main characters can become real threats, forever transforming how action stories are understood.

Attack on Titan colossal titans emerging from ocean during Rumbling event, massive skeletal titans crushing ancient stone walls, steam rising from their heated bodies, broken chains hanging from their necks, cinematic wide-angle shot, apocalyptic sky with dark storm clouds, glowing orange lightning illuminating destruction, photorealistic rendering, dramatic scale contrast between tiny human figures on wall and towering titans, debris particles floating in thick atmosphere, epic battle scene composition, dark fantasy visual style, motion blur on stampeding titan feet, realistic water splash effects

The technical development behind the narrative twist 🎬

Eren's transition was not a whim; author Hajime Isayama laid the groundwork from the first chapter. He used resources like foreshadowing and manipulation of the viewer's perspective to make the change believable. Visually, Eren's design evolved: his gaze became colder and his body language more rigid. The animation by WIT Studio and MAPPA reflected this with close-ups and somber color palettes. All of this built a coherent narrative where the hero's fall felt inevitable.

When the protagonist forgets to read the hero's manual 😈

It turns out Eren didn't attend the class on How to be a good shonen protagonist. While Goku hands out smiles and Naruto makes friends with his talk-no-jutsu, Eren decided his thing was crushing 80% of humanity. A bit extreme, yes, but at least he didn't sell us a 50-episode speech about the power of friendship. In the end, the Rumbling was his way of saying: If the world hates me, let the world burn.
