* AssPull: The whole "Dark Matter" [[spoiler: creation that Mr. Black used to create Astro's copy and Astro really being royalty. A few readers found that to be utterly implausible and flew against what the series was trying to establish: that you don't need to be from royalty to be a proper ruler. The fact that the series got CutShort didn't help matters.]]
* GermansLoveDavidHasselhoff: Had more of a fanbase with the American audience. As such it was given an English release.

* TooGoodToLast: Had an interesting concept and a lot of potential that just needed some polish. You could even see that it was shooting for a much more long term story with the focus on learning more about the Org, the addition of a female companion and much more evil organizations down the line with the intergalatic roadtrip around the planet and maybe even beyond to surrounding planets. Alas space dramas are a very tough sale in Japan, thus it couldn't gain an audience and was given a hasty ending.
* TheWoobie: Jino. She was always abused by [[spoiler:Fake!Barrage]] and is always terrified of making mistakes for fear of being struck to the point where she tears up whenever she thinks shes angered him. Even when she knows Astro won't hurt her, she still does the same.
