Despicable Me 4

Undercover Anti-Villain League (AVL) agent Felonious Gru attends a class reunion at his former high school Lycée Pas Bon where he reunites with Maxime Le Mal, a former classmate of his who has a feud with Gru for stealing his talent show act. During the ceremony, Maxime reveals he has enhanced himself with cockroach body parts to make himself overpowered and so he can conquer the world, but Gru has him arrested with the help of the AVL. Sometime later, helped by his girlfriend Valentina, Maxime escapes prison and reveals his new invention, a gun that transforms people into cockroach hybrids, which he plans to use specifically on Gru's infant son Gru Jr., who despises his father.
