Pierson's Puppeteers are a fictional alien species from the science fiction works of Larry Niven. They are known for their unique physical appearance, characterized by a three-legged body and a head that resembles a puppet. Their most notable feature is their ability to manipulate others through a combination of intelligence and social skills, which is reflected in their name. These aliens are also recognized for their advanced technology and strategic thinking. They are often portrayed as cowardly, preferring to avoid direct conflict and instead use cunning and manipulation to achieve their goals. This behavior has made them a significant element in Niven's Known Space universe.
