Unversed

Unversed (アンヴァース), meaning "those who were not well-versed in their own existences", are the main enemies of the game Kingdom Hearts Birth by Sleep. The Unversed possess some sort of connection to the Heartless and the Nobodies of the main series and are, in essence, "the opposite of human life". They are also known to "grow off of negative emotions". They are extensions of Vanitas and part of Master Xehanort's master plan. The Unversed symbol also appears on the Vanitas's Sentiment's helmet.

Kingdom Hearts Birth by Sleep
It has been revealed that the Unversed are dark beings created by Vanitas. As a human created from the purest, most raw form of darkness, Vanitas had the ability to manipulate the negative thoughts and emotions of people, and spawn them as the Unversed to further his goals, as well as Master Xehanort's goals. By every and all accounts, the Unversed are extensions of Vanitas himself, and part of his power and influence - effectively making him the "first and original Unversed". With Vanitas's destruction, the Unversed are completely wiped from existence.

Bosses
The Wheel Master was the first confirmed boss for Kingdom Hearts Birth by Sleep, fought by Terra and located in Enchanted Dominion. One included is the Unversed that resembles the pumpkin carriage from the Castle of Dreams which Aqua fights and also Symphony Master in Terra's story mode. Trinity Armor is a Unversed that appears in Radiant Garden in which Terra, Aqua, and Ventus fight as a three way battle. An Unversed called Metamorphosis is also shown to battle Ven and Terra in Space.

Appearance
Several types of Unversed have been shown in scans, including a small, skinny creature, blue in color, and a large creature also colored blue. They all seem to feature odd, red eyes and large, zig-zagging antennae/ears. There are flower-like Unversed that look like potted flowers with vines for arms that seems to spin like a top, and pot-like Unversed that are simply red pots with bat wings. Also, there are falcon-like Unversed and Unversed that are reminiscent to boots. A rabbit-like Unversed is also shown, with long floppy ears and tiny, stubby legs.

Trivia

 * Due to a translation error, the Unversed were previously known to English-speaking audiences as the "Unbirths".
 * The Unversed are the only enemy species to be controlled by only one person: Vanitas.
 * In addition, they are the only species to not have a playable character (unlike the Heartless (Sora's Heartless) and the Nobodies (Organization XIII) ).
