Lance Corporal Vivian Monroe is a soldier in the Columbia military and a minor character in BioShock Infinite. The daughter of Sgt. Monroe, who served under Cornelius Slate during the Spanish-American War and Boxer Rebellion, she followed in her father's footsteps and joined the Columbian Army when she moved.
Once a proud supporter of Zachary Hale Comstock, she later became disillusioned after seeing Comstock's mistreatment of the citizens of Columbia. Unable to serve under a leadership that betrayed and discriminated against its own people, Vivian left to join the Vox Populi, though nothing is known about what happened to her.
