The technique that Kylo Ren, a character from the Star Wars franchise, used to stop blaster bolts with the Force is known as "Force Stasis" or "Force Freeze." In the movie "Star Wars: The Force Awakens," Kylo Ren demonstrates this ability during a confrontation with the main protagonist, Rey, on the Starkiller Base.
Force Stasis allows a Force-sensitive individual to halt or suspend objects or energy projectiles, such as blaster bolts, in mid-air using the power of the Force. In the scene, Kylo Ren uses his outstretched hand to freeze a blaster bolt fired by Chewbacca's bowcaster, holding it in place momentarily. This action showcases his command over the Force and his proficiency in using the dark side of the Force.
The ability to manipulate objects or energy with the Force is a common power displayed by Force users throughout the Star Wars universe. However, the specific techniques and terminology used may vary depending on the individual and their alignment with the light side or dark side of the Force.
