Discotek Media released both movies on Blu-ray and DVD for the first time in North America on March 27, 2018.
However, while they're not paying attention, Death 18 swoops down from the sky and abducts Kiyomaro, carrying him away and leaving his friends baffled.
As Gash walks home, he thinks about the previous versions, or "generations", of Vulcan that had been ruined in the past (leading up to the third that he currently had), and how they are all important friends of his.
Screaming out that Kiyomaro's an idiot, Naomi, the local bully, believes that Gash was talking about her, so she starts pummeling him.
Gash thinks that Death 18 is another Vulcan that Kiyomaro built, and calls him "Yondaime", or "Fourth Generation".
Dr. M2 tells him that the idiots of his time can't understand him, but Kiyomaro says that Gash changed his view of people around him.
Kiyomaro manages to break free from his prison and communicates with Gash using a giant monitor on the side of the castle.
The attack also tears a hole in a part of the castle, though, leaving Kiyomaro to fall from the sky; however, Yondaime manages to catch him.
As the giant Vulcan attacks the group, Megumi, Folgore, and Sunbeam all arrive in a car together to help fight it off.
During the scuffle, Megumi casts Giga Ra Seushiru, causing the giant Vulcan's attack to reflect back at it, making it collapse.
Kiyomaro angrily snatches Gash's Vulcan from his hand, saying that it's just a toy made from chopsticks and a paper box that he scrapped together.
Suddenly, the storm around them intensifies, and everyone realizes that if they don't seal the time-space hole, then the entire Earth will be destroyed.
Dr. M2 reveals that if the destroyed reactor is fixed, the hole will close, but there would need to be a large amount of power to reactive it.
Redetermined, Gash and Kiyomaro launch a gigantic Baou Zakeruga, which crashes through Yondaime and splits into three heads, starting up the reactor.
The three Baou Zakerugas fly into the cloud, successfully closing the hole and leaving Dr. M2's fate unknown.
