Hybrid Heartless is an alternate type of featured in Avastar: Kingdom Hearts and The League of Abstraction. Although Avastar: Kingdom Hearts and The League of Abstraction use the same name, the explanation defining Hybrid Heartless is very different in each story.

Avastar: Kingdom Hearts
In Avastar: Kingdom Hearts, Hybrid Heartless are exactly as it sounds: Fusions of Heartless, or rather, fusions of the entity of Heartless: an experiment gone through by Bradley Millar. The fusions can be Pureblood/Pureblood, Emblem/Emblem, even Pureblood/Emblem.

Pureblood/Pureblood
This combination is difficult to produce, as such a pure form cannot easily be fused with the form intact. Although difficult, the combination is possible, and not as hard as fusing Emblems and Purebloods. As they are fused with only Purebloods, the Heartless Emblem is not present. (create)

 * Possessor X

Emblem/Emblem
This combination is the easiest combination, as the Emblem heartless were artificial to begin with. The Heartless Emblem is present. (create)
 * Silent Stalker

Pureblood/Emblem
This combination is extremely difficult to make. The Heartless Emblem is sometimes present on these Heartless, though not always. There are very few success stories in this combination, however, there are a few notable ones:
