There are latin Disney comics, just like Asterix. Probably more done for general educational purposes than for the Vatican market, but hey, you got to pin the name somewhere (and IIRC, for modern words in Latin the Vatican is often the official source)

Incidentally, the article seems somewhat wrong in attributing the comics that inspired "Dagobert" to the US and Carl Barks. A lot, if not most of these, were Italian originals that got translated into German (pretty well, which at least the article gets right). One could even nitpick the "outselling superheroes", because Phantomias, Donald Duck's alter ego is a thing.
