Unversed

The Unversed (アンヴァース) are monsters that appear in Kingdom Hearts Birth by Sleep. They attack Terra, Ventus, and Aqua on many occasions over the course of their respective journeys.

Kingdom Hearts Birth by Sleep
After Master Eraqus conducts Terra and Aqua's Mark of Mastery exam, the Unversed are unleashed in accordance with Master Xehanort's ambitions. In each of the worlds they plague, the creatures are attracted to negativity. They ultimately cease to be after Ventus fuses with Vanitas, who reveals the Unversed only existed to make Ventus stronger.

Kingdom Hearts III
As a result of Master Xehanort's plan to gather thirteen darknesses for the second Keyblade War, Vanitas is brought forward in time to clash with the seven guardians of light. The Unversed, and Vanitas's control over them, returns as well. Intrigued with how negative emotions are exploited in the world of Monstropolis, Vanitas sends hordes of Unversed to that world.

After Vanitas's defeat at the hands of Sora and Ventus, the Unversed cease to exist once more.

Design
Unversed come in many shapes, sizes, and colors. A key component of their design is emotion, thus their red eyes are made to resemble laughing, angry, and crying faces. The emblem that appears on the bodies of all Unversed represents a heart that expresses emotion.

Nature


Unversed are "those who are not well-versed in their own existences". They are the result of the negative emotions produced when Ventus and Vanitas were separated by Master Xehanort. The Unversed are extensions of Vanitas himself, thus they obey his every command.
