One idea could be a story where a cell gets accidentally transferred to a different part of the body and has to find its way back while facing new and strange environments. For example, a red blood cell might end up in the nervous system instead of the circulatory system.
One idea could be that Frieza and Cell team up to take over the universe in a new and unexpected way. They combine their powers and intelligence to outwit all the other powerful beings.
One idea could be that Cell somehow gets a second chance at life and instead of being a villain, he tries to team up with Goku. They could go on adventures together across different universes, facing new threats and learning from each other. Goku could teach Cell about the value of protecting the innocent, and Cell could show Goku some of his scientific knowledge about power levels and energy manipulation.
One interesting idea could be exploring how cells might hold unique ninja abilities or chakra signatures. For example, a cell could be the key to unlocking a new form of jutsu. Another idea might be cells that have memories of past ninja, which could lead to uncovering hidden secrets in the Naruto world.
One idea is to write from the perspective of a single organelle. For example, if you choose the lysosome, you can tell a story about how it's the cell's 'cleanup crew'. It goes around the cell, gobbling up waste and old cell parts. Another idea is to make the cell a character in a larger biological world. Maybe the cell is part of a tissue that's competing for resources with other tissues in an organism. You could also create a fantasy world where cells have personalities. The ribosomes could be the hard - working builders, always constructing proteins.
Well, a great 'Cells at Work' fanfic plot could involve a time - travel aspect. For example, what if a cell somehow gets sent back in time to when the body was first forming? They could witness how the different cell types originated and then use that knowledge to better protect the body in the present. Or, a fanfic could focus on a group of cells that get lost in a different part of the body than they're used to and have to find their way back while facing all sorts of new challenges.
One idea could be to explore what if Gohan had a different training partner before the Cell Games. For example, if Piccolo had trained with him more intensively, it might have changed his power level and fighting style during the games.
Maybe in the fanfiction, Cell could be re - created in a different form with a mix of other characters' DNA. He could have some of Piccolo's regeneration abilities along with Gohan's hidden power. This would lead to a whole new set of battles and power - level dynamics as the Z - fighters try to figure out how to deal with this new Cell.
One idea could be a story where Sam Fisher has to infiltrate a high - tech enemy base hidden deep in a jungle. The base is protected by advanced security systems and he has to rely on his stealth skills and new gadgets to get in. Another plot could be about Fisher teaming up with a young and inexperienced agent, teaching the newbie the ropes of the trade while on a dangerous mission in a snowy, mountainous region. A third idea is a fanfiction where Fisher discovers a conspiracy within his own agency and has to go rogue to uncover the truth.
One idea could be a story where Android 21, with her unique powers, has to team up with Cell. Maybe they are forced to work together to stop a greater threat that is endangering the entire universe. Their different abilities, like Android 21's cooking - which could have some hidden power - and Cell's regeneration, would make for an interesting dynamic.
Maybe the female cell comes from an ancient and powerful clan. Naruto has to figure out how to control this new power within him without being consumed by it. He could go on a journey to learn more about the origin of the cell and in the process, meet new characters related to that clan.
