A Dr. Haskel appears at Max's apartment and convinces Max that he has escaped from KAOS with his invisibility ray. KAOS kidnaps Max as he attempts to discover if the ray is for real or not. We are introduced to most of the protective devices in Max's apartment in this episode, including the invisible wall, the seltzer bottle/lamp club, the attacking desk drawer, the fireplace vacuum, and the cargo net. While funny, a much better invisibility episode occurs in the fourth season, One Nation Invisible.
