Banu was the daughter of National Data Corporation employee Haroun Sharif, who worked as vice president of operations at the Charybdis complex on LV-991. Banu lived at the facility alongside her father and extended family, including her mother Sanam and grandmother Nadia Khanoom. During a Xenomorph outbreak at the base, Banu was captured by the Midnighters, an elite unit dedicated to hunting the creatures, and was ultimately killed by a Xenomorph.
