Vault Boy, though never appearing directly in movies or television, is the mascot of the Fallout video game series. He is the cheerful, blond-haired, blue-eyed character depicted in Vault-Tec advertisements, manuals, and in-game interfaces. His origins are shrouded in mystery, with no definitive in-universe explanation for his existence.

Primarily used to illustrate stats, perks, and warnings within the Pip-Boy interface, Vault Boy's signature thumbs-up gesture has become iconic. Contrary to popular belief, this gesture isn't always a sign of optimism; it is actually a method of determining if one would survive a nuclear blast. If the thumb is smaller than the mushroom cloud, it meant certain death.

Beyond his functional role, Vault Boy represents the pre-war, idealized American optimism that contrasts starkly with the post-apocalyptic wasteland. His enduring popularity has made him a symbol of the Fallout franchise, appearing on merchandise and in promotional materials. He serves as a darkly ironic reminder of the naive promises of safety offered by Vault-Tec before the Great War.
