The thought bomb is an old and deadily sith power the thought bomb requiring vast amounts of darkside energy which is channeled and controlled by one person

The thought bomb when being conjured makes the air thick and hard to breath and those who are attuned to the force can feel the force being absorbed from things

when the bomb is detonated it causes a large physical explosion which decimates anything in its path as well as a large void in the force from the energy it uses

very few people are able to survive the thought bomb detonation those who fall victim to it are entrapped in a large metallic ore looking orb that surrounds the controller once in the orb it is impossible to remove the people entrapped

the thought bomb single handly eliminated all the jedi and sith on the planet ruusan calling for a new era and change in the ways of both the jedi and the sith
