Professor Eulalie “Lally” Hicks is a highly intelligent and powerful American witch, serving as the Charms Professor at Ilvermorny School of Witchcraft and Wizardry. A trusted friend and staunch ally of Albus Dumbledore, she plays a significant role in the global wizarding conflict against the dark wizard Gellert Grindelwald during the 1930s. Her character exists entirely within the Fantastic Beasts film series and associated materials, not appearing in the original seven Harry Potter novels.
Professor Hicks's background is primarily detailed through the Fantastic Beasts films and supplementary materials from Wizarding World. A descendant of a magical family, she eventually took up a teaching post at Ilvermorny, the North American wizarding school, where she became a respected Professor of Charms (Pottermore). During the rise of Gellert Grindelwald in the 1930s, Professor Hicks became a key correspondent and ally of Albus Dumbledore. Trusting her sharp mind and formidable magical skill, Dumbledore enlisted her help in his efforts to thwart Grindelwald's plans. She first assisted by creating a Portkey disguised as a book, which she sent to the No-Maj Jacob Kowalski to safely transport him to Hogwarts School of Witchcraft and Wizardry to join the mission against Grindelwald. Hicks later traveled to Berlin, Germany, with Jacob, Newt Scamander, Theseus Scamander, and Bunty Broadacre to disrupt Grindelwald's political machinations. She demonstrated exceptional dueling prowess and quick thinking, protecting Jacob and confronting Grindelwald's acolytes. Her final key involvement was in Bhutan, where she participated in the complex plan involving multiple identical suitcases to confuse Grindelwald's followers during the election for the Supreme Mugwump of the International Confederation of Wizards. She bravely dueled several dark wizards to ensure the integrity of the election and expose Grindelwald's deception with the Qilin (Fantastic Beasts: The Secrets of Dumbledore).
As depicted in the films, Eulalie Hicks is a tall, elegant, and stylish witch. She carries herself with an air of confidence and authority, often dressed in sophisticated 1930s attire that is both practical and fashionable (Fantastic Beasts: The Secrets of Dumbledore). Professor Hicks is characterized by her sharp intellect, bravery, and unwavering loyalty. She is quick-witted, often with a dry sense of humor, and is exceptionally perceptive. As a Charms master, she is a logical and strategic thinker, able to analyze complex magical situations and devise effective countermeasures. Despite her formidable power, she is also compassionate, showing great warmth and encouragement towards Jacob Kowalski, whom she deeply respects for his courage. She is a determined and principled individual, utterly committed to opposing the prejudice and tyranny of Gellert Grindelwald.
