13 years after Despicable Me, Illumination has finally confirmed what happened to the film's villain, Vector, after the movie ended. The original Despicable Me movie released in 2010 introduced audiences to Gru and the Minions, as they were transformed from world-threatening villains to part of a caring family with Margo, Edith, and Agnes. Adopting the girls originally began as part of a ploy for Gru to defeat fellow villain Vector, who stole a shrink ray. This leads to Vector shrinking and stealing the moon, only for Despicable Me to end with Gru, the girls, and the Minions defeating Vector, leaving him stranded on a fully resized moon.
