Maddy runs into Mal when she returns to Maleficent's ruined apartment. She tells Mal about Maleficent's apartment being ransacked and how everyone had stolen or destroyed Maleficent's belongings. They leave the apartment and go to the Slop Shop to get some "Slop-Shop Specials" and run into Carlos and Evie. Immediately Maddy and Evie are unknown to one another and Evie takes a disliking to the witch. She refuses to tell them anything about the Anti-Hero meeting and leaves them.

She is next seen by Mal, Evie, Jay, and Carlos going into the Evil Queen's cellar to attend the Anti-Heroes meeting along with several other villain kids. When the gang sneaks into the cellar behind them, she surprises them with cake.

She leaves the meeting early and lures Mal (and unknowingly Evie) away from the Anti-Heroes. She leads her down to the Rickety Bridge where her allied VKs are waiting in hiding. She tells Mal that she received a letter from an anonymous source saying that the missing Evil Queen, Cruella De Vil, and Jafar would return to Doom Cove after midnight from the Catacombs beneath the island.

However, it is revealed to be a lie. Maddy lured Mal to be attacked by her gang of friends who believe the Anti-Heroes club is a futile attempt. They accept their lot in life and refuse to believe they can be good. Maddy was a part of the Anti-Heroes club as a spy for her comrades. She tells Mal that she hated her all along and that she was always planning to destroy her ever since she came back to the island. With help from Ginny Gothel, she pushes Mal into the waters surrounding the Isle and leaves her there to be eaten by the crocodiles. But when Evie, Jay, and Carlos come to save Mal she flees from the bridge and tells them they will burn like Camelot.
