What A Pip Boy Is In Fallout Season 1 Explained

The Pip-Boy is a key part of the Fallout video games’ mythos – so, what exactly is it? And which model appears in Season 1 of Prime Video’s Fallout show?

What Is a Pip-Boy In Fallout Canon?

The Pip-Boy is a wearable computer; “Pip” stands for “Personal Information Processor.” Developed by RobCo Industries before the Great War, the Pip-Boy was standard issue equipment in all Vault-Tec Vaults. That said, Vault-dwellers aren’t the only Wasteland inhabitants rocking these devices post-War. Notably, the Free States militia has its own Pip-Boy stash in Fallout 76. Other Wastelanders will also go to great lengths to obtain a Pip-Boy – and with good reason. Depending on the model, a Pip-Boy boasts the following capabilities:

tracking the wearer’s health and inventory storing text files, images, maps, and audio recordings providing directions and alerting the wearer to nearby hostiles (via a built-in compass) monitoring radiation levels (via a Geiger counter), and illuminating dark areas (via a built-in flashlight).

A Pip-Boy can also grant access to sealed Vaults, as revealed by Moldaver using Rose MacLean’s Pip-Boy to infiltrate Vault 32 in Fallout Season 1. How exactly Moldaver pulled this off remains unclear, however, as Rose’s Pip-Boy (like all of them) is biometrically locked to its user.

Which Pip-Boy Model Appears in Fallout Season 1?

In total, six canonical Pip-Boy models exist: It’s unclear which (if any) of the above models appear in Fallout Season 1, although the device sported by Lucy MacLean looks like a 3000-series variant. Regardless, the Pip-Boy props Lucy actor Ella Purnell and her co-stars wore were surprisingly functional. Indeed, Purnell’s on-screen dad, Kyle MacLachlan, raved about his working Pip-Boy in a recent Total Film interview. “I love working with the little Pip-Boy,” MacLachlan said. “Taking that idea, an animated concept, and turning it into a real piece of working equipment, that was really fun. They actually did program some stuff in there that we could play with… little location things [and] some other movement. It was all pre-programmed, of course, but you actually had something you could interact with which is not just a blank something that you’re looking at.” Fallout Season 1 is now streaming on Prime Video.
