Leader of U.S.S. squad Delta, otherwise referred to as the "Wolfpack", she often times is spearheading them into battle. Lupo has garnished great respect from her squad, so much so that they have even gone as far is to nickname her "Wolf Mother". Before her time with Umbrella, she was a member of a French special ops detachment; but with the allure of fortune and better tech, she quickly joined the U.S.S.
According to Adam Bullied, the lead writer of Operation Raccoon City, Lupo is ''a single mother in her late thirties with four kids and no work experience outside the military''. He created this backstory as a means to help visualise why anyone would choose to work for a company like Umbrella.
