The theme of self - destruction often appears. Gon's transformation into a dark version of himself can lead him down a path of self - destruction. He may overextend his power or make choices that are harmful to himself. Another common theme is the loss of identity. As he becomes dark, he may lose the essence of who he originally was. And the theme of broken relationships is also prevalent, as his darkening can cause rifts with his friends and allies.
One common theme is the exploration of their deep friendship evolving into romantic feelings. Often, it's about the moment when they realize their connection is more than just friendship. Another theme could be about them overcoming some external obstacle together, and the kiss is a celebration of that victory.
A very common theme is the exploration of unspoken emotions. In the original 'Hunter x Hunter' series, there are a lot of feelings between Killua and Gon that are not fully expressed. In fanfiction with a kiss, it's a way to finally let those emotions out. There can also be the theme of forbidden love in some cases, where they might face challenges or opposition to their relationship, and the kiss is a rebellious act against those constraints.
One theme that shows up a lot is sacrifice. Killua's willingness to sacrifice for Gon and vice versa is a big part of their relationship. In fanfictions, this can be magnified, with one sacrificing in a more extreme way for the other's well - being or for the sake of their relationship. Also, self - discovery is a theme. As they grow closer, they might discover new things about themselves and their feelings for each other.
One common theme is redemption. Qui - Gon often travels back in time to correct mistakes, either his own or those of the Jedi Order. This gives him a chance to redeem himself or the Order in some way. For example, he might try to prevent a Jedi from falling to the dark side.
In 'killua x gon lemon fanfiction', a recurring theme is the protection of one another. In the original story, they already show a great deal of loyalty and a desire to protect. In these fanfictions, it can be amplified, especially in situations where their relationship is at stake. There might also be themes related to the contrast between their different personalities - Killua's more cautious and Gon's more impulsive nature - and how they complement each other in their relationship.
One common theme is growth. Fans often write about Gon growing in power and wisdom. For example, in many fanfictions, Gon discovers new Nen abilities and learns how to control them better.
A prevalent theme is the idea of legacy. Qui - Gon's death has a huge impact on Obi - Wan, and fanfictions often explore how Obi - Wan continues Qui - Gon's legacy. Also, the theme of friendship is common. Beyond just being master and apprentice, they are friends, and this is often shown in how they support and trust each other in various situations.
One common theme is self - discovery. Since Gon is a different gender in these fanfictions, she often has to re - evaluate who she is. Another theme is friendship, as she still interacts with the same group of friends like Killua and others.
One common theme is the exploration of power dynamics. Hisoka is much more powerful than Gon and Killua at first, so fanfics often play with how they either try to overcome this gap or how Hisoka uses his power in relation to them.
Many 'gon x hisoka fanfic' also have the theme of redemption. Hisoka is a rather morally ambiguous character. Fanfics may explore if and how he can be redeemed through his relationship with Gon. It adds depth to the story and makes for a more complex and thought - provoking read.
