The Amnesia-inator is one of Heinz Doofenshmirtz's -inators. It got used by the O.W.C.A. to erase the memories of select non-O.W.C.A. people who had helped repel 2nd Dimension Heinz Doofenshmirtz's invasion (Phineas and Ferb The Movie: Across the 2nd Dimension). The Amnesia-inator was also in A Real Boy, but titled as the Forget-About-It-Inator.
