Perhaps in this fanfiction, Cell somehow ends up in Bulma's laboratory. She initially panics but then realizes she can study Cell. Cell, on the other hand, is interested in Bulma's scientific knowledge and they start a strange alliance that eventually turns into an unexpected friendship.
There's a possibility that an evil scientist from another planet could be the main antagonist. This scientist wants to use Bulma's knowledge and Cell's power for his own evil experiments. So he tries to break up their partnership and capture them both for his own purposes. He sends his minions after them and creates various obstacles for Cell and Bulma to overcome.
The contrast in their characters. Bulma is a brilliant scientist and Cell is a bio - engineered being. Their interactions can be really fascinating as they come from such different backgrounds. It's like two opposite poles attracting each other in a way.
There is also 'Cell's Redemption through Bulma'. This fanfic shows how Bulma's influence might lead Cell to a path of redemption. It's a long - form fanfic that goes deep into the emotions and possible character growth of both Bulma and Cell. It's really engaging as it shows a side of their relationship that we don't often see in the original series.
One possible plotline could be that Cell, seeking to prove his superiority, challenges Broly. Broly, in his usual berserk state, accepts without hesitation. The fight could start with Cell trying out his various attacks like the Kamehameha - like Solar Flare and his physical strikes. But Broly's power is just too much and he starts to overpower Cell. However, Cell then reveals a new, hidden ability that he has been developing in secret and the tables are turned for a while.
Another possible ending is that Gohan sacrifices himself to defeat Cell. He could use a self - destructive move that not only takes out Cell but also costs Gohan his life. This would be a very dramatic and tragic ending, but it would also show Gohan's selfless heroism.
One possible storyline could be Aj Lee starting off as the underdog. She might be facing some early setbacks from Paige's aggressive attacks. But then, Aj Lee could use her quick thinking and unique in - ring skills to turn the tables. Maybe she manages to avoid Paige's big moves like the Paige Turner near the cell walls and then counter with her own finisher, the Black Widow, to win.
Yamcha could potentially betray Bulma. Even though they have a history together, in a fanfic scenario, he could be jealous of Bulma's growing closeness with Vegeta or her scientific achievements. So, he might do something to undermine her, like spreading false rumors about her work.
One major difference is that plant cells have cell walls while animal cells don't. This makes plant cells more rigid. Also, plant cells have chloroplasts for photosynthesis which animal cells lack. Instead, animal cells rely on consuming other organisms for energy.
I'm not sure specifically what a 'catherine cell' is in this context as the term is rather unclear. It could be a very specific or made - up concept within that particular story.
