Even though twenty six episodes were made, only twenty two aired.
Galvion did not fare very well and had its planned number of episodes cut; a 23rd episode was partially completed but did not air. Episode 22 was a typical episode but had a 35-second epilogue tacked onto the end that explained the series' planned outcome via voice-over narration and stills.
Galvion is one of the last shows to be produced by the anime company Kokusai Eigasha before pulling out of the industry completly, around the end of 1984. This was due to financial issues.
The series was finally released on DVD in Japan on July, 26, 2013.
