It could be a rogue ninja who also has a devil fruit power and wants to steal Naruto's Mera Mera no Mi ability. Maybe he has a water - based devil fruit power and sees Naruto's fire - based power as a threat to his own plans for domination.
Perhaps in the fanfiction, the Mera Mera no Mi's power is modified when Naruto has it. Since Naruto has a large amount of chakra, the fire produced by the fruit could be enhanced in a way that it can even burn through powerful ninjutsu defenses. For example, when facing Sasuke's Amaterasu, Naruto's Mera Mera no Mi - enhanced fire could counter it in a unique way.
One common theme is the clash of two different worlds. Batman is from the dark and gritty Gotham, while Mera is from the underwater kingdom. Their different backgrounds often lead to interesting conflicts and cultural clashes in fanfictions.
Adventure is a big theme as well. Given Goku's love for fighting and exploring, and Mera's own adventurous spirit in some interpretations, they embark on all sorts of quests in fanfics. They could be searching for a lost artifact or trying to stop an evil force from taking over a particular realm.
I'm not entirely sure as I haven't specifically studied the 'yeh dil mera ending' in great detail. It could potentially be about the final resolution of a love story, perhaps with the main characters finally getting together or going their separate ways depending on the plot of the related work.
I'm sorry, but I'm not familiar with the specific 'mera khuda janay full story'. It could be a very specific story from a particular culture, region or personal account that I haven't come across yet.
The significance could lie in how it satisfies or subverts the audience's expectations. If it's a happy ending, it gives a sense of closure and hope. For example, if the story was about a difficult love, a positive ending would signify that love overcomes all.
Sure. One great batman and mera fanfiction is 'The Meeting of Two Worlds'. It's a story that explores what would happen if Batman and Mera's paths crossed in a rather unexpected way. It has a great plot with lots of action and interesting character interactions.
A common theme is the struggle between their different responsibilities. Mera has her duties in Xebel and Aquaman has to rule Atlantis. Their love often has to navigate these political and leadership obligations.
