Liberty Prime is a giant combat robot from Bethesda's Fallout series, first introduced in Fallout 3 in 2008 and returning in Fallout 4. Built in the game's lore by the pre-war United States military, the character is known for shouting anti-communist and pro-democracy slogans while throwing explosives and firing lasers. Clips of his voice lines spread through gaming forums, YouTube edits and meme communities, where the exaggerated patriotism became shorthand for unstoppable American force, and the lines remain popular with Fallout fans today.
