Really sucks when some ******* comes by just to be hateful and whatnot. Some people can't just let others have their enjoyment talking about things they like. At least they're gone for now.
Realistically I can see only 2-3 movies left for the MonsterVerse. I'd love for it to be the case but its never gonna reach what the MCU achieved.
In this case, this is how I'd do it.
Godzilla (2014)
Kong: Skull Island
Godzilla: King of the Monsters
Godzilla vs. Kong
Godzilla 3 (Main Baddies: Biollante and Gigan; Mothra returns)
Son of Kong (Climax or post-credits has Kong and son along with mate as well being forced back to the surface due to events hence Kong's role in Destroy All Monsters)
Destroy All Monsters (Main Baddie: Destoroyah)
I'd be pretty content with that.
What I would actually like:
A Mothra movie that has her face off against a pre-cybernetics Gigan(basically, to reference their Final Wars rivalry and fight) and the end credits scene leads up to Gigan's revival via cybernetics and machinery, making him look like the original/Final Wars design.
Three Godzilla movies.
-The first one is Godzilla versus Hedorah. Hedorah is no longer a monster of pollution, but a monster created from radiation and various chemicals from various radiation accidents, like Chernobyl and whatnot. Hedorah becomes less of a cartoony pollution monster and becomes more akin to a slow mobile Chernobyl incident. Hedorah is not inherently malevolent and shows no malice, but it's existence is too dangerous to keep alive and is a threat to the living world, which ends with Godzilla destroying Hedorah.
-The 2nd movie focuses on the humans trying to find ways of stopping and fixing the damage from Hedorah and it's destruction, leading up to various creations with plants and eventually, Biollante, a creature created from plant cells and Godzilla cells in an attempt to absorb the growing radiation. Biollante is not a malevolent creature and is friendly to the humans it was created by, but eventually, something wrong happens that ends up with Biollante getting loose. This incident could be an incident that induces a fear episode into Biollante into an unintentional rampage, other monsters sent to go after her by an outside factor, whether it'd be an evil organization, an hostile alien race, etc. Gigan and it's new form are involved and eventually Mothra and Godzilla come into the mix, which at first has Godzilla see Biollante as a possible threat, but it ends with Biollante surviving at the end of the movie and her appearance in the 3rd movie.
-The third movie is Godzilla and Biollante versus Destroyah, a creature that ends up being created by the remains of the Oxygen Destroyer/Remover/etc from the first Godzilla movie and the aftereffects of the radiation left by Hedorah's destruction. Biollante aids Godzilla against Destroyah who's very being brings destruction and radiation where it goes as it tries to destroy everywhere. The movie ends with Biollante and Destroyah being destroyed, but the remains of Biollante become a catalyst to heal the destruction that was left, like the one Godzilla comic story.
That would be somewhat my take of some ideas for future Monsterverse movies and whatnot. Was somewhat rushed, but at least the main concepts are there.
