Designed in 1984 by Egon Spengler and Ray Stantz, the Proton Pack counters the negative energy which ghosts are made of. The Proton Stream emits from the induction nozzle on the Particle Thrower. A Proton Stream, is a stream of positively charged ions which can harness a ghost. The Proton Stream is very dangerous and barely controllable. Egon has also mentioned that crossing Proton Streams will result in total protonic reversal causing all life as we know it to stop instantaneously and every molecule in a user's body to explode at the speed of light.
