Vault Boy on Fat Man

Vault Boy's iconic grin radiates cheerful chaos as he rides atop the Fat Man nuclear catapult, tipping his hat with breezy confidence. Cloudy Nostalgia's design captures the beloved *Fallout* mascot in his signature blue and yellow vault suit, rendered against a clean white background. Warm olive and amber tones define the atomic bomb beneath him, accented by a glowing atom symbol — retro-apocalyptic charm at its finest.
