The Twilight King

"Echo, one day you will realize that our power has no limit. One day you will realize why we are destined to reign supreme"

- The Twilight King

Background
The Twilight King is an alternate future reincarnation of Echo Uchiha. Apparently he obtained an item known as The Crest of Twilight and used it to conquer the physical realm. He guides Echo in the present to the Land of Bane in hopes of continuing his dark cycle of chaos. In the end Echo succeeds in obtaining the Crest but somehow does somethign that the Twilight King himself was unable to do, merge with it. They then have a battle for power that shakes existence and Echo defies destiny by defeating himself in the future, and overall saving humanity.

Abilities
Nothing has yet to be shown of his abilities but it is implied that he s extremely powerful as evidenced by him bringing all resistence against him to extinction.

Personality
The story of the Twilight King is a mystery because it is stated that he is not the true incarnation of Echo, meaning that by using the crest he somehow altered his destiny. In that sense he is extremely selfish and takes no disrespect or threat lightly.
