Johnathan is a Lowcust (Demon/Humanoid hybred by fusion magic) due to an accidental merging with Deamon, the demon that killed his sister infront of him. He comand the powers of the Left Eye of Xorn, allowing him to mimic anything he sees. For the alledged killing of his sister, his oldest brother, Nathan Nocturne, banished him to the Dimension of Man, where he now resides in New York City, defending it from any and all demons that find a way out of the Darkness. Upon his left arm, he wears the Left Talon of Xorn, allowing him to perform powerful magic spells.
As compared to his other half, Deamon, Johnathan is calm, collective, kind, and will only fight when neccissary.
