Balthazar Bratt (voice of Trey Parker) joins the AVL with Gru (voice of Steve Carell) and Lucy (voice of Kristen Wiig) to stop a new Female Villain, she uses jewels for weapons, like emeralds to make duplicates of herself to help her fight, pearls as smoke bombs, etc. She also uses a special pendant to hypnotize people by singing. They need Bratt because he used to know her even before he was an actor and they had some type of relationship (Jewel used to have a huge crush on Bratt when they were young and still does.) We later find out her parents turn out to be Scarlet Overkill and Herb Overkill, she uses her father's inventions and ideas from a journal he had and her own ideas to create her gadgets. She uses her mother's skills and style to help her fight(she even steals the same ruby Scarlet stole in the Minions movie), but she also uses Bratt's way of fighting (dancing and singing to heist music). She's also out to get Gru for destroying her mother's reputation and causing her parent's arrest in England which caused her to grow up by herself. Besides another villian Gru has another problem on his hands, the girls' biological parents show up and could destroy Gru's family.
