What is Gru's alma mater called in Despicable Me 4?

Gru’s alma mater in Despicable Me 4 is called Lycée Pas Bon.

Lycée Pas Bon is a school for aspiring villains, and Gru returns there for a class reunion near the beginning of the film. The reunion also brings him face to face with Maxime Le Mal, a former classmate who still resents Gru over an old talent-show rivalry.

The French name is a joke: “pas bon” means “not good,” making the school’s name roughly equivalent to “Not Good High School.” The setting resembles a grand boarding school or castle and establishes that Gru received formal training in villainy before eventually changing sides.

The school becomes important again when Poppy Prescott blackmails Gru into helping steal its honey badger mascot, Lenny. That plot explains why the academy is more than a brief flashback location. It also helps distinguish the name from invented alternatives such as École Vector or Académie Belle Bottom, neither of which is the school’s canonical name.
