Liberty Prime is a unique U.S. Army robot found at the Citadel. It stands 40ft tall and is extremely heavily armed, making it a major combat asset. Liberty Prime was found and brought to working order by the Brotherhood of Steel. Its total restoration was due to the assistance of Dr. Madison Li, who solved Prime’s power issues in the year 2277. After its destruction at the Satellite relay station in the same year it remained in disrepair until 2287, where it is then in the process of being restored to assist the Brotherhood division in Boston.
