The Deluxe Extreme Ghostbusters figures were part of the Trendmasters Extreme Ghostbusters Toy Line. They were figures of the Ghostbusters with large suped-up weapons.
Kylie Griffin's Deluxe Figure came with a weapon that was pretty much a large ghost trap with a proton gun attached. It may have been an attempt to emulate how on the show Kylie carried the trap on her back and used a smaller proton gun.
Egon Spengler's Deluxe figure wore a blue jumpsuit and came with the Field Projector.
Eduardo Rivera's Deluxe figure came with a rather large and bulky Proton Pack.
Garrett Miller is currently the only Extreme Ghostbuster who never had a publicly released action figure, though a prototype was made.
