* BaseBreakingCharacter: Is Zin a worthy successor to Kamijo, or a [[ReplacementScrappy cheap imitator]]? Don't answer that.
* ItsTheSameNowItSucks: The band got some flak initially for essentially (literally) being Music/{{Versailles}} with a different vocalist. The release of "Blessing of the Future" did virtually nothing to quell this notion, being musically similar to a lot of Versailles music, but ''Classical Element'', with its ProgressiveMetal influences and other experimental elements, quieted them down a bit.
* TheyChangedItNowItSucks: The existence of the band itself is mildly controversial among Music/{{Versailles}} fans (the phrase "it's just not the same" comes up a lot), but Zin himself has become divisive, with the occasional "Kamijo vs. Zin" FlameWar flaring up. The fact that Zin sometimes comes across as a SuspiciouslySimilarSubstitute to Kamijo does ''not'' help.
* ToughActToFollow: Since Versailles were a popular and acclaimed band, a lot of people treat Jupiter as a successor to Versailles. While the members insist that Jupiter is a separate band completely unconnected to Versailles, and that their music should be judged on its own merits, rather than being compared to their previous output, the fact that their lineups was 80% identical (at first) means that the comparisons were inevitable.
