Vadim and his identical twin brother Yefim Bobrov are of Eastern European ancestry and are the proprietors of the Dugout Inn, a bar and hotel which is a popular hangout spot for Diamond City's lower-class residents. He is a rather cheerful and friendly fellow who enjoys joking around with his customers, who can rather be quite loud. Vadim is the polar opposite of his colleague Yefim, the innkeeper of the Dugout, who possesses a more quiet and reserved personality.

Vadim has a penchant for treating his personal finances as part of his establishment's expenditures, much to the chagrin of his brother, who consistently reminds him to pay his bills. He insists on serving drinks every hour of the day, however he needs to exercise using his inside voice while behind the bar, and assisting Scarlett with keeping the place neat and tidy.
