There's also 'Jake and the Mysterious OC'. In this fanfiction, an original character enters Jake's life and they have to work together to solve a mystery that could potentially endanger the whole Jaeger program. It has a really engaging plot.
To start, do a lot of research on Jake's character from the movie. What are his motives? His fears? His dreams? Once you have a clear picture, you can start building your OC around that. Decide on the role your OC will play in Jake's life. It could be a love interest, a mentor, or a partner in crime - fighting Kaiju, that is. Outline your story, including the beginning, middle, and end, and start writing, making sure to keep the Pacific Rim feel throughout the story.
There could be a Pacific Rim OC fanfiction where the OC is a new pilot. This pilot has a special ability like being able to sense Kaiju movements from a greater distance than normal. The story could revolve around their journey of proving themselves in the face of skepticism from other pilots and commanders in the Shatterdome.
One common theme is self - discovery. The oc characters often start out not fully understanding their place in the Pacific Rim world and then through their experiences, they figure out who they are. Another theme is friendship and teamwork, as they have to work with the existing characters in the Pacific Rim universe to fight the kaiju.
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.
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 common theme is adaptation. The oc gamer has to adapt to the high - stakes world of Pacific Rim. For example, learning how to pilot a jaeger which is very different from gaming in a virtual world.
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.
First, think about your OC's backstory. Decide who they are, where they come from, and what their motivation is. For example, if they're a pilot, why did they choose to become one? Then, consider how they fit into the Pacific Rim Uprising universe. Are they part of an established team or a new recruit? After that, start with a strong opening scene that introduces your OC and the situation they're in.
Pacific Rim was an American sci-fi monster movie set in the future on Earth. In 2013, a parallel universe portal known as the Breakthrough Point appeared in the depths of the Pacific Ocean. A large group of alien monsters (Kaiju) emerged from it and began their invasion of Earth. The attacks of these monsters caused human casualties and losses. The world predicted that the disaster would never end. In order to fight against these monsters, humans collaborated to develop a weapon that could fight against monsters. It was called Jaeger. A mecha hunter was a huge robot, controlled by two operators who were connected to each other through the neural network in their brains. Humans relied on the mecha hunters to fight against the monster forces, which was the prelude to the monster war that lasted for several years. As the monsters continued to evolve, the mecha hunters were gradually defeated. The politicians of various countries tried to build defensive walls to stop the invaders, but they soon encountered setbacks. At this critical moment, General Steke Pantecaster found the pilot of the "Dangerous Wanderer" who had suffered a major blow five years ago and chose a new partner for him through strict selection.
