If Hange had never worn the cape , the story would barely change on the battlefield, but their visual identity would feel less iconic. The cape is part of the Survey Corps uniform, so losing it would mostly affect appearance, movement, and how fans recognize Hange rather than their actual role in the plot.

In-story effect

Hange’s core traits are their intelligence, curiosity, and leadership, not the cape itself, and their importance comes from research and command decisions. The cape would not change their ability to lead the Scouts or fight Titans.

Visual impact

The cape helps make Hange instantly recognizable as a Survey Corps officer, especially in battlefield scenes. Without it, their outfit would look more like a practical uniform than a distinctive character design.

Fan interpretation

A lot of fans connect Hange’s look with the wider Survey Corps image, so removing the cape would probably make them feel a little less dramatic and memorable. In cosplay or fan art, that would likely reduce the ā€œinstant Hangeā€ effect people associate with the character.

Overall

So the short version is: no cape, same Hange , but with less visual flair and less of that classic Survey Corps silhouette. Their personality and story role would stay the same; only the presentation would change.
