Peter comes with a non-removable proton pack and proton thrower gun. He also comes with a Ghostbuster logo figure stand.The final accessory that was included with Peter is a proton stream that can be attached to the end of the thrower.
This proton steam is a slightly flexible translucent plastic lightning effect. It is molded in translucent blue and red plastic. Peter is a pretty nice figure. I wish I could get Egon and Winston now.
