One reason could be the contrast between the characters. Broly is extremely powerful and somewhat of a wild card, while Gohan has his own unique power and personality. Their interactions in a fan - made story can be really interesting.
There are so many fanfics out there, and to find good 'broly x gohan fanfic', you could also join some Dragon Ball - related forums. Fans often share and discuss their favorite fan - made stories there. Maybe someone has already found some great 'broly x gohan' ones and can point you in the right direction.
A really interesting plot could be that Broly trains Gohan in a parallel dimension where the rules of power are different. Gohan has to learn to adapt to this new environment while also dealing with Broly's tough training. This could lead to some really cool power - up moments for Gohan.
In a Broly x Gohan fanfiction, Gohan could develop a new understanding of power. Instead of just relying on his academic knowledge and some of his traditional training, he could learn from Broly that power can also be about pure instinct. Meanwhile, Broly could develop his mental faculties. Gohan might introduce Broly to things like meditation or mental focus exercises. As a result, Broly becomes less of a mindless brute when it comes to fighting and more of a thinking fighter, which would be a significant character development for him.
The fanfic might show that Broly, despite his usually aggressive nature, has a soft spot for Gohan's potential. He could see Gohan as a worthy successor to the Saiyan power. So, he trains Gohan with a kind of rough love. During the training, Gohan might struggle at first with Broly's intense regime. But as time passes, he starts to adapt and even surprises Broly with his growth. They could form an unlikely bond through this training process, which could be a central theme of the fanfic.
I'm not entirely sure if there is a specific 'Gohan x 18' fanfic. While the idea of pairing these two characters is interesting, not all fanfics are easy to find. Some might be on specialized fanfic websites, while others could be hidden in less - known corners of the internet. You could try searching on well - known fanfic platforms like FanFiction.net or Archive of Our Own, but there's no guarantee that you'll find one right away.
Well, the plot might involve Broly somehow getting stranded on Earth where Gohan lives. Gohan, being the kind - hearted Saiyan - human hybrid, decides to help Broly adapt. In the process, they train together. Gohan tries to teach Broly about control, while Broly shows Gohan new levels of power. Their friendship grows and they end up protecting Earth from other threats that come their way.
In general, a 'chichi x broly lemon fanfic' might attract a lot of attention from fans who are interested in exploring non - canonical relationships in the Dragon Ball series.

I'm not sure specifically about a 'good' Gohan x Lavender fanfic. But often in fanfics, authors take creative liberties.

It could be that in some fics, they are brought together by a common goal, like saving a planet or a particular group of people. You really have to explore different fanfic communities to find one that you'll enjoy.
