Dark Avatar

Dark Avatar's powers and abilities

Waterbending Unlike the Avatar, the Dark Avatar did not have the ability to bend all four bending arts, since Unalaq could only waterbend prior to his fusion with Vaatu, unlike Wan, who went to the lion turtles with Raava and received all four elements.

The Dark Avatar State Despite the limitation of only bending one element, the Dark Avatar's bending potential could still be significantly augmented by a dark variation of the Avatar State, in which Vaatu provided Unalaq an energy surge which allowed him to accomplish great feats of waterbending, such as creating large waves capable of dispersing several battleships. In this state, Unalaq's eyes glowed orange as opposed to the white glow of the Avatar's eyes when they entered the Avatar State. Due to being fully aware of his spiritual capabilities, Unalaq had full control over the Dark Avatar State the moment he became the Dark Avatar and he was able to trigger the ability with ease whenever he found it appropriate to use.

UnaVaatu After vanquishing Raava, the Dark Avatar underwent a physical transformation, becoming a massive giant as tall as a skyscraper, with enhanced powers and physical attributes from both Unalaq and Vaatu. However, despite his humanoid appearance, the Dark Avatar's new form bore a strong resemblance to Vaatu's spiritual form, retaining his tentacle-like appendages. His skin color and body markings resembled those of Vaatu's spiritual form as well. Being that the two were so closely connected in this form, this extreme fusion is termed "UnaVaatu". Unalaq's waterbending was far more powerful in this form than in his Dark Avatar State, with UnaVaatu able to create a giant wave proportionate to his size that easily defeated the United Forces fleet. UnaVaatu was also able to spiritbend on a larger scale, which he used against Korra's astral projection. Furthermore, UnaVaatu possessed several of Vaatu's abilities that the Dark Avatar had never demonstrated, such as fighting with tendrils and shooting energy beams from the markings of his chest.
