This is the Delta Plasma, a die-cast transformation item of Ultraman Great, released by Bandai. It does not include any transformation sounds, but the center part flashes. As shown in the image, it has been tested and confirmed to work. The button battery has been replaced with a new one and is installed in the main unit. Due to the passage of time, the box shows signs of deterioration. Furthermore, the plastic that originally held the main unit in place inside the box is missing, so please understand that the main unit will be wrapped in bubble wrap, etc., and stored in the box. Also, as depicted on the box, the original chain attached to the main unit was very short, but I was not satisfied with it, so I found and replaced it with a longer chain that is closer to the one in the show. By the way, the original short chain is missing. About two and a half years ago, at an event at Nakano Sun Plaza, Mr. Dore Kraus, who played Jack Shindoh, came to Japan and held a talk & autograph session. I have a fond memory of having Mr. Dore Kraus himself hold the Delta Plasma and flash the center part for a photo. For those who will cherish it, please consider purchasing it.
