Gru’s Flying Scooter Personality At first, Gru was a sneaky and somewhat cold-hearted man, who was determined to become the greatest villain in the world. At first he showed a dislike of children being easily irritated by Agnes , Edith and Margo. He was self-centered and in the beginning, he only adopted the girls so that he could get the shrink ray which he intended to use to shrink the moon so that he could steal it. Gru is also rather cruel and even sadistic at first and enjoyed using his Freeze Ray , which is his signature weapon often freezing people just for the sake of it. Despite these traits, Gru is shown to be good friends with Dr. Nefario and also treated his Minions quite well interacting with them and calling each one of them by name he can also understand their language instead of just treating them like slaves. However, he also said that he had no intention of giving his minions a raise. As time went on, Gru started to enjoy spending time with his three adopted daughters and in the end he grew to genuinely love them, putting aside his dream of stealing the moon and risking his life to rescue them from Vector. Nefario disapproved of the fact that Gru’s warmer side is starting to reveal itself and sent the girls back to the orphanage.
