Ghost (Changeman)

Ghost appeared in 1985 TV series called Dengeki Sentai Changeman. Ghost is a Space Beast of the Great Star League Gozma. A bug-eyed Space Beast with the ability to turn invisible, allowing for motion without being seen and to avoid all attacks being thrown at it. It also possesses electrical energy and an ability known as "Ghost Fire", which it can emit a powerful flame from inside it's body. Ghost was the Space Beast used by the Gozma for the conquering of planet Polo, but while appearing successful it unexpectedly let two of the Polonians escape: Koko and Kiki. The duo come to Earth due to hearing the planet possessing diamonds, which were needed alongside their own energy emission in a dual beam (a natural and a diamond-enhanced one) to disable Ghost's invisibility, allowing for it to be attacked. With the EDF assisting in giving the duo a diamond for usage, they reveal Ghost with their power, allowing for Oozora (who had been primarily helping them) to attack and disable him further with the Pegasus-Zooka, then destroy with the Power Bazooka. Ghost regained his invisibility after Gyodai rebuilds him, but the double beam once again makes him tangible enough to be destroyed by Change Robo. Ghost had a dark and sinister personality using his invisibility to terrorize an entire planet into submission and taking hostages to get what he wants.
