Enigma Heartless

Enigma Heartless are enemies appearing in Kingdom Hearts: Sorrowful Echoes.

Kingdom Hearts: Sorrowful Echoes
Seeking all the memories in the universe, the Enigma Heartless attacked and consumed several worlds.

Nature
The means by which Enigma Heartless are created is never explained in the game. They share characteristics with both Pureblood Heartless: in that they lack an emblem and do not release hearts when destroyed, and Emblem Heartless: in that they come in a wide variety of forms.

Enigma Heartless rarely seek out hearts, unless provoked. They show more interest in the memories, thoughts, and knowledge of people.
