Defect is the overall antagonist of the story. They are a virus that has been summoned by Toon Link, and though they promise to grant him power, their intentions are truly dark. They should speak in a slow, smooth, hypnotic, almost ASMR-esque voice. Their intention is to use charisma and charm to persuade Link into believing that they are his only friend. Defect, also taking on a masculine phyisique,  has no specific gender, so they can be voiced by anyone. All you need is the ability to be sickly sweet and sickly twisted.
