Together, the tools can summon Activitron, a gigantic spectral robot that will appear every chapter to defeat a monster that will inevitably grow bigger when it's about to lose. Ed is the robot's right arm, Isabel its left, Mr. Spender is the legs, Isaac is its crippling self-doubt, and Max is the head, which has a detachable hat-shaped escape pod. Also that is not true and Paranatural's not really about fighting a different spirit every chapter. Thanks for reading!
