1) Mothra vs. Godzilla (1964) = Mothra's fairies were featured here and speak on behalf of Mothra. They also converse with the photographer Junko who also gives the big passionate speech to Mothra and her people, which serves as the big declaration of the moral of the film.
2) Ghidorah the Three Headed Monster (1964) = Mothra's fairies are back, this time as essentially political diplomats and celebrities. They even devise the plan to have Mothra get Godzilla and Rodan together to fight Ghidorah. There is also a bizarre subplot about a princess that escapes as assassination attempt, but wakes up believing she is an alien prophetess. She predicts when and where all the monsters will show up and provides an explanation for what Ghidorah is. An female investigative reporter is also around and tries to get the scoop on the princess' story. There is at least a couple scenes where all four female characters are featured together.
3) Godzilla Vs. The Sea Monster (1966) = Again, Mothra's fairies are involved. This time played by different actresses and have a much smaller role, but they help save everyone at the end of the movie. Also, we have the native woman Daiyo who provides the other characters with information on who the villainous Red Bamboo are. She was also the only native to successfully escape captivity from the Red Bamboo, so extra woke points there.
4) Destroy All Monsters (196

= Well the alien invaders, The Killaaks, are all women here, and the test doesn't specify that the women can't be villains. They actually manage to be the least silly of Godzilla's many alien invaders.
5) Godzilla Vs. The Smog Monster (1971) = Bit of a stretch here as the main women in the family don't converse much, but they all have active roles, whether it be caring for an injured husband, or actively participating in Hedorah protests.
6) Godzilla Vs. Gigan (1972) = The main characters in this one are basically a Scooby Doo gang, but without the talking dog. There are two women in the gang, one of whom is a karate expert that beats the crap out of the aliens at one point and makes fun of her dopey cartoonist boyfriend (actually, are they couple? The movie was never really clear). The other major female character gets the ball rolling on uncovering the aliens' plot after her brother disappears. She steals the important mcguffin tape from the aliens.
7) Godzilla Vs. Mechagodzilla (1974) = There is the Azumi priestess who awakens King Ceasar, the daughter of the scientist who admittedly doesn't play a huge role, but there is a female archeologist in the film, and all three of them are present towards the end, commenting on what is happening and moving the story forward to its monster filled finale.

Godzilla Vs. King Ghidorah (1991) = The Heisei series featured Miki Segusa as a recurring character, making her the main character of the series for a lot of people. She is a psychic that uses her powers to help against Godzilla and eventually form a bond with him. In this film, she converses with one of the time travelers, Emi Kano, about their plan to erase Godzilla from the timeline, and Miki is also the first one to realize that Emi released the Dorats, eventually resulting in the birth of King Ghidorah. Emi has a redemption arc and is responsible for stopping Godzilla at the end of the film.
9) Godzilla Vs. Mothra (1992) = Mothra's fairies are back!
10) Godzilla Vs. Mechagodzilla (1993) = G-Force's Mechagodzilla team includes Miki Segusa and an American pilot who knows karate (and is a terrible actor by the way). Miki also converses with the main female lead of the film, Azusa, as both of them start to realize that killing Godzilla might not be the way to go.
11) Godzilla Vs. Spacegodzilla (1994) = Weird that this one passed since there are romantic subplots abound, but Miki is back and there is Dr. Gondo, both of whom want to pursue non violent ways of stopping Godzilla and step in to tell the pigheaded men how wrong they are!
12) Godzilla Vs. Destroyah (1995) = Miki is losing her psychic powers and has a new psychic student that pals around with her throughout the film. There is also Miss Yamane, a great grand daughter to the Dr. Yamane of the original film and niece to Emiko, the female lead of the original film, and we see Aunt and Niece converse with each other.
13) Godzilla 2000 (1999) = Io is probably one of the most bearable kid characters in the entire series and we see her bond with Yuki, who pals around with Io's dad's Godzilla watch network and eventually comes to form kind of a family unit with them.
14) Godzilla X Megaguirus (2002) = The main character is Kiriko, a female and is a high ranking officer in the G-Graspers group and her immediate superior that she converses with is a woman as well.
14) Godzilla Against Mechagodzilla (2002) = Akane is the lead and deals with a bunch of personal issues and guilt and shit, and there is Sara, a little girl upset over her mom's death and they bond throughout the film.
15) Godzilla Final Wars (2004) = Although the men carry most of the action, there are women scientists, officials, and reporters throughout the film that converse and don't talk about men.
16) Shin Godzilla (2016) = High ranking political officials, diplomats, and experts of both genders converse, plan, and strategize to stop Godzilla. No talking about men.
