Form [better] - Eren First Titan
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.

The exposed muscles aren't a weakness; they are a declaration. This is a boy who will bleed openly for his freedom. The most important detail about this form is

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. This specific Titan form serves as the prototype for Eren’s character arc: raw, unrefined, and driven purely by instinctual hatred. He doesn’t fight to save Armin or Mikasa;
