Dr. Martin Brenner

Martin Brenner (portrayed by #MatthewModine) is the head scientist of Hawkins Laboratory and the experiments performed there. He is a callous and manipulative scientist, having abducted Eleven from her mother, whom he later subjected to electroshock therapy to destroy the woman's mind. Brenner then put Eleven through numerous experiments (project INDIGO) before she escapes after using her abilities to establish a link to the Upside Down. He and his team hunt for her throughout Hawkins while covering up the actions of the Demogorgon they unknowingly let loose.
