Since 'lemon' fanfics are not something I can promote in detail due to their potentially inappropriate nature. However, in a proper fanfic about Gohan and Trunks, it could show how they support each other in their growth as Saiyans. For example, they might share new techniques they've learned or strategize about upcoming battles.
I'm not sure about specific 'gohan and trunks lemon fanfiction' as it might involve non - canon or inappropriate content. But if you're looking for regular Gohan and Trunks fanfiction, there are many platforms like FanFiction.net where you can find great stories about their adventures and friendship.
Since 'lemon' usually implies inappropriate content, there are no positive aspects in that regard. However, if we consider a regular Gohan and Trunks fanfic, it can be positive as it can expand on their relationship and character development.
In some fanfictions, when Gohan trains with Whis, he might quickly master new techniques. For example, he could learn to control his ki in more precise ways, like creating energy blasts with different shapes and functions. This would make him a more formidable fighter in the Dragon Ball universe of the fanfiction.
The plot might involve Beerus noticing Gohan's slacking in his training compared to his earlier days. So, Beerus decides to whip him back into shape. He could start with basic physical training like making Gohan run around a huge planet multiple times a day. Then, he moves on to teaching Gohan some new and powerful ki techniques that are unique to Beerus' own combat style.
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.
There really isn't much that's acceptable in the context of 'lemon' fanfiction as it usually involves sexual or inappropriate content. However, if we were to consider fanfiction in general about Gohan and Trunks, themes like their friendship, training together, and fighting against common enemies are common and great.
One common theme is friendship. Since they are two of the last remaining warriors in a desolate future, their friendship is crucial. They support each other, whether it's in battle or in dealing with the emotional toll of their situation.
One common theme is friendship. They often rely on each other in fanfictions, showing a deep bond of friendship. Another theme is power - how their combined powers can be used to face great threats. For example, in many stories, they train together to become stronger. And there's also the theme of sacrifice, where one might be willing to sacrifice for the other to save their world or loved ones.
