"Imagine Breaker" is a fictional ability from the light novel and anime series Toaru Majutsu no Index. It is possessed by the character Touma Kamijou and allows him to negate any supernatural power or ability that comes into contact with his right hand. This makes him a unique figure in a world filled with various powers and abilities. The ability is not limited to just one type of power; it can nullify magic, psychic abilities, and even divine interventions. However, Imagine Breaker does not affect ordinary physical objects, making it a double-edged sword in battles against powerful foes.
