Spiritron

Spiritron
A spiriton is the fundamental particle of the supernatural and metaphysical in the Bleach universe. Spiritons are unique since they are invisible to mortals (such as humans with the exception of talented ones such as Quincy); they can however still interact with normal matter and produce physical effects as a indication of a spirit being; for example the infamous flying trick where ordinary matter is suspended from spiritual matter giving the appearance to a human that the object is flying (for example when Kon was abducted by a Hollow).

Spiriton's seem to come in two flavors ; solidified spiritons appearing as normal matter, (albeit with the capability of forming matter that would be impossible to create using regular matter (for example soul slayers))and energy type,in this form spiritons appear as form of energy which is normally used by the protagonist as form of projectile weaponry. When in energy form a spiriton can be of a variety of colors depending on their source (each spirit being having there own unique hue of spiriton particle)
