The most important detail about this form is who is not in control. Later, Eren fights with strategy, hardening his knuckles, learning to grapple. In his first transformation, there is no "Eren." There is only the raw, directive-less Id. He doesn’t fight to save Armin or Mikasa; he fights to destroy the nearest threat. He swings blindly.

Eren’s first transformation is arguably the most pivotal moment in the early narrative of Attack on Titan . It shifts the genre from a bleak survival horror into a mystery-laden battle shonen.
