It's unlikely if Megalon will ever be recruited for another Godzilla movie, he was pretty much of a one time character and despite this he is pretty popular (at least in the U.S. probably). Like most of the monsters seen in picture they have some popularity, but aren't cut out for a return and if so it might as well be a cameo appearance, these monsters have the exact same equivalence as the Dragon Ball Z characters in my opinion (e.g, Nappa is Megalon's equivalent) some of the characters who appear one time usually are given a cameo later on and no special after their debut or just don't appear at all, but manage to be recruited into video games. It is pretty self explanatory.
