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.

They return in Kingdom Hearts III and make their primary appearance in Monstropolis. They also appear in the Keyblade Graveyard as enemies.

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, return as well. Intrigued with how negative emotions are exploited in the world of Monstropolis, Vanitas sends hordes of Unversed to that world. On the Laugh Floor at the Monsters Inc. factory, the Unversed utilize the company's former business model of deploying Scarers into children's bedrooms to collect scream energy, allowing them to accumulate enough negative emotion to reconstitute Vanitas's heart.

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. All Unversed, with the exception with the Flood, are emblazoned with an insignia that represents a heart that expresses emotion.

Lesser Unversed usually tale smooth or bulbous forms, looking akin to toys. Boss Unversed typically have sharper and better-drfined features.

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. They only exist if Vanitas also exists, and if Vanitas is destroyed, they also are destroyed. However, certain Unversed like Cursed Coach and Symphony Master were drawn to the negative emotions of Lady Tremaine and focused on trying to carry out her wishes to harm Cinderella.

Because the Unversed's essence flows back in Vanitas, he can use this accumulate negative emotions to empower and heal himself. The Unversed only exist in worlds Vanitas has been to.

Yen Sid believes that the Unversed will inevitably attack the Seven Pure Lights Indeed, Master Xehanort put a barrier around Aurora's room to keep the Unversed out. Plus they drawn to Snow White, Cinderella and Kairi; all of whom they attacked.
