As soon as he was introduced and the source of the Avatar cycle was revealed, many fans began to speculate about the concept of a Dark Avatar and wondered if Unalaq was planning on merging with him. This especially became the case when it was revealed that Unalaq had been visiting Vaatu and planning something with him. Unalaq did eventually end up fusing with Vaatu and became the Dark Avatar.
