Hunter 'Hap' Percy is The OA's chilling antagonist — a brilliant, obsessive scientist who abducts and imprisons people who have had near-death experiences, conducting cruel experiments to study what lies beyond death. Coldly rational and utterly convinced of the importance of his work, Hap is a captor who frames his monstrousness as scientific devotion.
His arc is a study in the banality and seduction of obsession. Hap holds Prairie and others captive for years, and the complicated, fraught dynamic between captor and captives — part horror, part twisted intimacy — drives the show's mystery. As the series expands across dimensions, Hap follows, an inexorable pursuer whose pursuit of knowledge knows no moral limit.
Jason Isaacs's coolly menacing performance made Hap a memorably unsettling villain.
