Well, in a fanfiction where Naruto is trained by Deidara, Naruto's creativity in combat would probably skyrocket. Deidara is all about his explosive art, and Naruto could learn to use chakra in ways he hadn't thought of before. Maybe Naruto would start using the environment in a more explosive way during battles, like turning rocks into mini - explosives like Deidara does with his clay. Also, Naruto might have to struggle with Deidara's nihilistic attitude towards life at times, but it could also make him more empathetic towards enemies with different outlooks in the long run.
When trained by Deidara in fanfiction, Naruto's view of art could change. Deidara has a very distinct view of art as something that is transient and explosive. Naruto might start to see the beauty in destruction in a way, which could make his character a bit darker. His attitude towards his enemies might also change. Instead of always trying to redeem them, he might be more willing to use forceful and destructive means to defeat them, as he has learned from Deidara's combat approach.
In some fanfictions, Deidara might give Naruto training on explosive jutsu control. Since Deidara is known for his explosive clay techniques, he could potentially teach Naruto how to better handle and utilize explosive elements in combat.
In a fanfiction, Deidara and Sasori could be sent on a secret mission to infiltrate a hidden village. Deidara uses his clay creations to distract the guards while Sasori sneaks in with his puppets. As they progress, they discover a powerful weapon that the village is developing. They then have to decide whether to destroy it or take it for the Akatsuki. Along the way, they also have to deal with their own internal conflicts and the pressure of the mission.
They could be on a journey to find a rare material for Deidara's art. Sasori, with his knowledge of the ninja world, helps guide them. Along the way, they encounter various strange creatures and ninja clans. They might have to fight off some who are after the same material.
There's a fanfic called 'Deidara's Redemption in Naruto's World'. In this story, Deidara has a change of heart after multiple encounters with Naruto. It delves deep into how Naruto's unwavering belief in the good of others starts to affect Deidara and his view of the ninja world.
One idea could be that they discover they are brothers in a hidden past plot twist. Maybe their parents were from different villages but fell in love secretly. As brothers, they could team up to face a new and powerful enemy that neither could defeat alone.
In this fanfiction, their brotherhood might lead to a cultural exchange between Iwa and Konoha. Naruto could introduce Deidara to Ichiraku Ramen, and Deidara could show Naruto some unique Iwa traditions. As they do this, they also have to face some who oppose their new relationship, thinking it might be a threat to the balance of power between the villages. But they prove everyone wrong with their strong bond and how they use their combined skills to protect both villages.
Often, these fanfictions focus on the complex relationship between the two characters. They might explore the contrast in their personalities, like Naruto's optimism and Deidara's more artistic and explosive nature. This contrast can create interesting dynamics in the story.
In 'naruto and deidara yaoi fanfiction', there is often a focus on the emotional depth of the two characters. Since they come from different backgrounds (Naruto from Konoha and Deidara from the Akatsuki), there is a lot of room for exploring how they bridge that gap. It also usually involves a lot of dialogue to show their changing feelings towards each other. For instance, they might start off as enemies but gradually realize they have more in common than they thought. The fanfiction also tends to play with the themes of loyalty and betrayal as they are important in the Naruto universe and can be used to add drama to their relationship.
