Liberty Prime is a giant combat robot from the Fallout video game series, first introduced in Fallout 3 in 2008. Built in the game's fiction as a pre war American superweapon, the character was later rebuilt by the Brotherhood of Steel and returned in Fallout 4. His lines were written as exaggerated patriotic propaganda delivered in a booming robotic voice, which made short clips easy to quote and share. Fans spread the voice lines through gameplay videos, forums and meme edits, and the character remains one of Fallout's most recognisable symbols.
