Voltes V's Possible Plothole: General Bergan
Looking at what Voltes V established was that in Boazan, the hornless were slaves. So if General Bergan has no horns (if he has, they are possibly undersized or he lost them in battle) is a general for Zanbazil? There's some possibility to this one... probably as a slave he was kiss-ass to royalty. I mean Zanbazil did at one point offer La Gour/Dr. Gentaro Gou his position as minister of science back if... the latter would agree to help him invade other planets. So possibly, Bergan had some talent in science even if he was of lowly birth so he was promoted.
