As far as I know, nothing. There is nothing about Boss Borot, Venus A or Jet Scrander. What you see there is what was originally published both in Mazinger Z and Great Mazinger. The change has more to do with how it changed publishers and how busy was Nagai at the time. Generally speaking, all comic books published in Shueisha's magazines can only be re-printed by Shueisha. Same with all other Japanese publishers, where you might see that a series stops in a magazine and returns under another title in another magazine. Mazinger Z was one of the first comic books in which Dynamic Production keep the publishing rights and for reasons which I do not know the manga was transferred to Kodansha. But the main reason why the next chapters seem different is because, at the time, Nagai was busy with Devilman. He even had to drop Abashiri Ikka despite its success at the time. That is why the last stories are less complex until the beginning of Great Mazinger. Also, note that the anime was first, the manga was second, in the sense that the anime is an original product that is not based on the manga, so the manga did not have to laid out all the story beforehand, even more in Kodansha's TV Magazine which focused on manga that had an anime on air.
