Has the new Gundam series copied Aldnoah Zero?
I think both series are just drawing upon many common tropes and most prominently ∀ Gundam, which sports a very similar plot to both series and also predates both.
Although in that case it's the Moon instead of Mars and it's more about an ongoing invasion than trying to be liberated from anything.

More examples include, the majority of the rest of the Gundam Franchise.
