Egon Spengler

Egon is the primary engineer behind the Ghostbusters' iconic equipment, including the proton packs, ghost traps, PKE meter, and containment unit. He continually tinkers and improves upon these technologies, showcasing his ingenuity and understanding of paranormal physics.

Following the decline of Ghostbusters, Egon dedicates more time to independent research, exploring fields such as alternative energy, interdimensional travel, and advanced theoretical physics. He may have consulted for scientific institutions or government agencies on classified projects. He remains somewhat reclusive but committed to his scientific endeavors.
