Not every human character in Monarch: Legacy of Monsters is a friendly face. Certain figures carry shadowy secrets as they hunt the main characters around the world. Tim and Duvall are two Monarch agents tasked with researching confidential documents about Titan activity and their classified history. Played by Joe Tippett and Elisa Lasowski, the characters accelerate the pace of the Apple TV+ series and remind everyone of the globe-trotting stakes in between the colossal monster mash.
