Respect Unalaq

After today there will be no more Water Tribe; no more nations of any kind. The world is about to be transformed into something magnificent, and new. And I will lead this glorious revolution.

History: Unalaq was born the second in the line of succession to lead the Northern Water Tribe after his older brother Tonraq. Though Unalaq successfully manipulated events so that Tonraq was banished from the Northern Water Tribe and Unalaq took his place on the throne, there was more power in the world Unalaq coveted: that of the Avatar. To make matters worse, the new Avatar was Tonraq's daughter, Korra.

Early in his life Unalaq joined the anarchist organization the Red Lotus, which believed in joining the Spirit World with that of the humans, freeing the dark spirit Vaatu, and dismantling the Four Nations. Though Unalaq aided the Red Lotus in planning to abduct Korra as a child, he betrayed the organization and abandoned them. Secretly Unalaq wanted the power of the Avatar for himself.

After many years of planning Unalaq's plans partially became a reality. The Spirit World was united with the human world and he became a new Dark Avatar after freeing Vaatu. The light beat out the darkness in the end, however, and both Vaatu and Unalaq were destroyed by Avatar Korra.

Powers: Unalaq was a powerful waterbender and a foremost spiritual expert. He could "spiritbend" water around a target to either bring peace to them or destroy their soul. He later fused with Vaatu to become the Dark Avatar, seemingly enhancing his powers and gaining new shenanigans.
