Brad Kilsten, a German operative of NOA, wields gravity-based psychic powers. He manipulates gravitational forces to ensnare opponents and summon environmental objects like meteors and boulders for offense and defense. His documented techniques include Meteor Hammer (striking with two meteors from opposite sides), Mega Pressure (dashing forward to slam targets with a giant snake-like force), Gravity Infinity (creating a hindering black hole that drags in debris), and Asteroid Belt (generating protective boulders that become projectiles).

Kilsten suffers from severe dissociative personality disorder. His primary personality is a gentleman reluctant to fight. However, exposure to blood triggers a cold-blooded, homicidal secondary personality. This violent alter emerges during blackouts; he frequently regains consciousness on roadsides at night, confronted by corpses and overwhelmed by an unsettling sense of euphoria. These uncontrollable episodes instilled profound fear regarding his own existence.

Interpreting a telepathic message from Keith Evans as potential salvation, Kilsten sought out and joined NOA, hoping the organization could provide resolution or relief from his condition.
