For their final exam, Maximus tricked Betty and her crew to coming to their academy to teach a class, disguising it as a normal school. Betty and X-5 were caught and suspended above a vat of acid, but Betty managed to escape by convincing the Evil Juniors that to be truly evil, they needed to double cross their teacher, Maximus. When Maximus was caught, Betty used the distraction to break loose, Sparky (who had arrived at the scene and had also been captured) accidentally caused the vat of acid to tip, almost hitting the Evil Juniors, but Betty rescued them and took them back with them.
