Robert Lutece and Rosalind Lutece, collectively known as the Lutece twins, are a duo of characters from the BioShock video game series created by Ken Levine, published by 2K Games. They debut in the 2013 video game BioShock Infinite, where they serve as the drivers for the game's events and often materialize under mysterious circumstances to guide protagonist Booker DeWitt. By the game's end, both characters are eventually revealed to share no family relations, and are in fact parallel universe versions of the same individual. Robert and Rosalind are voiced by Oliver Vaquer and Jennifer Hale respectively. Concept artist Claire Hummel was responsible for the visual design of the Lutece twins.
