Sherry is a spontaneous and somewhat mysterious woman who travels around the Mojave Wasteland with her pet nightstalker, "Nibbles".

Very little is known about Sherry, and whilst she does not seem to have any real malicious intent, she does enjoy causing chaos and intentional problems for others for fun.

She has been seen on many occasions following various induviduals around, usually from a distance and hiding before they notice. Sherry seems to have a particular interest in those who have more active and "excitable" lives, leading to the conclusion that she finds these induviduals entertaining to watch and mess with. She has been known to stalk Graves around the Mojave.

Sherry has a special fondness towards the Boomers, sharing their passion and interest in explosives and weaponry. Despite this, Sherry has yet to manage to infiltrate Nellis Air Force Base, even though she manages to have shockingly good luck when dodging their artillery rounds. Surprsingly -- or maybe unsurprisingly -- Sherry seems to have made a game out of the Boomers' defense methods; running around the outskirts whilst she's fired at, coming very close to the fences, and then suddenly disappearing for the day, before reappearing another day to repeat the process.

At first, the Boomers assumed that she was scoping out the area, suspecting her of being an NCR spy, but after this ritual went on for several weeks without any changes or "reinforcements", they began to realise that this was her strange way of "playing" with them. Some of the Boomers have grown rather fond of Sherry's antics and look forward to her showing up, though others find her a nuisance.

Although Sherry doesn't appear to be nefarious, she is a known cannibal, and is often seen feasting on the remains of people who have "accidentally" fallen victim to her explosive antics.

During the Second Battle for Hoover Dam, Sherry was seen fighting both NCR troops and Legionaires, mostly by haphazardly throwing grenades into the ongoing conflicts. She didn't appear to ally with either side or have any particular motive, likely just excited by the thrill of the battle and having "fun".
