In Despicable Me, Gru’s youngest adopted daughter is Agnes.
Agnes is the smallest of the three orphan sisters adopted by Gru: Margo, Edith, and Agnes. Her cheerful personality, love of unicorns, and trusting nature make her one of the film’s most recognizable characters. The girls initially approach Gru while selling cookies, but their relationship changes the direction of his life.
Agnes is younger than Edith and Margo, which is why she is often shown needing more protection. Her attachment to Gru gradually becomes mutual, helping turn the story from a supervillain adventure into a family comedy. A common mix-up is confusing Agnes with Edith, the middle sister, or Margo, the oldest sister.
Agnes also appears in later Despicable Me films and related Minions media. Her unicorn obsession becomes a recurring character detail, especially in scenes involving toys, plush animals, and family outings.
