In Kaiju Wars fanfiction, some of the more popular characters are those who have a personal vendetta against the Kaiju. Maybe a character whose family was killed by a Kaiju and is now on a mission for revenge. Another popular type is the underdog character, someone who seems weak at first but then discovers hidden strength and becomes a key figure in the fight against the Kaiju. There are also the Kaiju themselves that can be popular characters, especially if they are given unique personalities or backstories in the fanfiction.
Often, the main human protagonists who are brave and resourceful are popular. For example, a fearless military general who leads the fight against the Kaiju. Also, any character with a special ability like a scientist who can understand the Kaiju's behavior.
Some of the lesser - known Kaiju can also be interesting to include in fanfiction. For example, Rodan. He has his own unique abilities and personality. A fanfiction could explore his backstory more deeply, or create a new relationship between him and the other more well - known Kaiju. Anguirus is another one. He could be portrayed as a loyal ally to Godzilla, or have his own motives for being involved in the Kaiju Wars.
The main character, Kafka, is often a popular one in fanfiction. Writers might put him in various new situations or develop his character further, like exploring his emotions more deeply during battles.
Blake Belladonna is quite popular in RWBY Kaiju fanfiction. Her stealth abilities can add an exciting element when she has to sneak around a kaiju or gather intel on it. Yang Xiao Long is another favorite. Her powerful punches could be portrayed as being able to at least stun a kaiju for a short time, and her fearless attitude makes her a great character to face these huge monsters. Also, characters like Qrow Branwen might be popular as they can bring in their experience and unique skills to deal with the kaiju situation.
Kafka Hibino is often a popular character in fanfics. His transformation into a kaiju - like form and his struggles to control it make for great storytelling. Writers can explore his inner thoughts and how he copes with his new abilities.
One popular character might be a kaiju girl with the ability to fly. Her aerial battles against other kaiju or threats are often a highlight in many fanfics. She is usually depicted as strong and independent.
One idea could be to write a story from the perspective of a civilian caught in the middle of the Kaiju battles. Show their fear, their attempts to survive, and how they interact with the military trying to stop the Kaiju. Another could be a story about a Kaiju that has unique abilities not seen in the original lore, and how it changes the dynamic of the wars. Maybe it could be a Kaiju that can communicate with humans and tries to form an alliance against the more destructive Kaiju.
A great plot for Kaiju Wars fanfiction could be centered around a team of international soldiers who are specially trained to fight the Kaiju. They could have different skills and weapons from various countries. The story could follow their adventures as they face off against different types of Kaiju in different locations around the world. There could be internal conflicts within the team as well, such as cultural differences and different fighting styles. And perhaps they encounter a Kaiju that is much more intelligent than the others, which forces them to come up with new strategies.
New original characters created specifically for the fanfiction can also become popular. For instance, a character who is a Kaiju whisperer, someone who can understand and communicate with Kaiju. This character can bring a whole new dynamic to the relationship between humans and Kaiju in the fanfiction world.
Well, of course, the main character who is reincarnated as a kaiju. There are often scientists or military personnel who are trying to deal with the appearance of the kaiju. Some fanfictions might also have other kaiju as characters, either as friends or foes to the reincarnated kaiju.
One popular kaiju human fanfiction could be about a human forming an unexpected bond with a kaiju. For example, in some stories, a scientist discovers that a kaiju has a more complex emotional range than expected and they start to communicate in a unique way. This challenges the common perception of kaiju as just mindless monsters.
