How about a Kaiju that can split into multiple smaller versions of itself? This would be a strategic advantage as the Jaegers would then have to deal with several threats at once. Each smaller Kaiju could have a different ability, such as one being able to spit acid and another being extremely fast.
To write a compelling Kaiju character, start by giving it a distinct appearance. Describe its size, color, and any unique features like spikes or tentacles. For example, a Kaiju with a massive, spiked shell on its back is immediately more interesting.
Perhaps a story where a baby Kaiju is accidentally transported to a different dimension. In this dimension, it's the only Kaiju, and it has to adapt to a completely new environment. Meanwhile, the humans in the Pacific Rim world are trying to find a way to bring it back, not knowing how it will have changed in this strange new place.
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.
One interesting plot could be a human and a Kaiju forming an unexpected bond. For example, a young scientist discovers a Kaiju that is different from the others, not as aggressive. They start to communicate in some way, maybe through telepathy or signs. This challenges the traditional view of Kaiju as just mindless monsters.
Good fanfiction about a Pacific Rim baby Kaiju should have well - developed characters. Besides the Kaiju itself, the human characters should be interesting too. They could be Jaeger pilots, scientists, or just regular people caught up in the situation. Build a story around their interactions with the baby Kaiju. Also, use dialogue effectively to show the different personalities. For instance, a scientist might talk in a very technical way, while a street - smart character would use more slang. This will make the story more engaging.
One idea could be a kaiju fanfiction where the kaiju form an alliance with humans to fight against an even greater threat from outer space. It would be a unique twist on the usual kaiju - human conflict.
One idea could be an OC who is a brilliant but unorthodox engineer. They come up with new Jaeger designs that are initially scoffed at but prove crucial in a battle. For example, a Jaeger with the ability to split into multiple smaller units for more flexible combat.
One interesting kaiju oc fanfiction could be about a new kaiju that has the ability to control elements. It teams up with the known kaiju to fight a greater evil. Another might focus on a kaiju oc's origin story, like how it came to be in this world. There are also those that explore the relationships between different kaiju ocs, which can be really engaging.
Kaiju novels often portray kaiju as gigantic and powerful beings. They are usually depicted as forces of nature that are difficult to control or defeat. For example, in 'Godzilla' novels, Godzilla is shown as a nearly indestructible creature with its atomic breath and massive size.
One idea could be that Godzilla emerges in the world of Pacific Rim during a Kaiju attack. The Jaegers initially see Godzilla as another threat but then realize he's actually fighting the same enemy. They could team up, with Godzilla's raw power and the Jaegers' advanced technology combining to defeat the Kaiju once and for all.
