Perhaps the idea of how technology from the 'War of the Worlds' gets incorporated into the TF (transformation) aspect. It could be that a character's transformation is powered by the advanced alien technology, leading to really cool and unexpected powers and forms.
Another concept could be the role of different factions in the fanfiction. In the 'War of the Worlds' setting, there are the humans, the aliens, and in the TF aspect, there might be groups of transformed individuals. How these different groups interact, ally, or fight against each other can make for a really engaging story.
Another concept might be character development. Fanfiction often delves deeper into the characters. In 'the war of the worlds fanfiction', we could see the main character becoming a more strategic leader, learning from each encounter with the aliens and growing in ways not explored in the original.
In War of the Worlds fanfic, a common concept is the survival of the individual in the chaos. Some stories focus on a single character's journey through the desolate, war - torn landscape. They might have to scavenge for resources, avoid both alien and human threats. Also, the idea of the aliens having a weakness that is not in the original story is often explored. Maybe it's a certain frequency of sound or a type of plant that can harm them. This gives the humans a glimmer of hope in an otherwise hopeless situation.
Sometimes, there are side characters like scientists or military personnel who play important roles. The scientists could be the ones trying to understand the TF process and use it to humanity's advantage, while the military personnel might be involved in the battles against the aliens and the transformed threats, all while trying to protect the world.
Well, in Naruto Floating Worlds fanfiction, there might be the concept of different power hierarchies. Since the worlds are floating, perhaps the shinobi who can control the movement or stability of these floating areas hold a great deal of power. Also, the idea of new forms of summons. Instead of summoning animals from the regular world, they could summon creatures that are native to the floating worlds. And there could be a new form of ninja training that involves adapting to the unsteady terrain of the floating areas.
In 'human into anthro pokemon tf fanfiction', the concept of power and its implications is cool. A human becoming an anthro Pokemon might gain a significant amount of power. This power could be used for good, like protecting the Pokemon world from threats. But it could also lead to corruption if not properly controlled. Additionally, the cultural differences between humans and Pokemon can be a great source of story. How does a human - turned - anthro Pokemon adapt to Pokemon traditions, like their mating rituals or their way of celebrating certain events? It can create a lot of drama and interesting plot twists.
One interesting concept is the re - imagining of well - known characters in different settings. For example, taking a classic fairy - tale character and placing them in a modern, post - apocalyptic alternate world. Another concept could be the creation of entirely new species or races that are unique to the alternate world. Also, exploring different social structures and power dynamics in these worlds can be really engaging.
One interesting storyline could be about the different cultures clashing in a more in - depth way. For example, how the modern Earth military deals with the unique magic and social structures of the other side of the gate. Another might focus on individual characters' growth as they are thrust into this new world of war, like a young soldier learning to respect and adapt to the alien cultures. And there could also be a storyline about a diplomatic solution being attempted in the midst of all the chaos, which would involve lots of political intrigue and negotiation between the two sides.
In 'god of war worm fanfiction', a cool concept might be the idea of Kratos facing off against some of the most powerful entities in the Wormverse. His skills as a warrior would be put to the ultimate test against foes with strange and unpredictable powers.
One interesting concept could be the fusion of the unique combat styles from RWBY and the gritty, military - themed combat of Gears of War. For example, seeing how RWBY characters would adapt to using the Lancer or the Hammerburst. Another concept might be the interaction between the Grimm from RWBY and the Locust from Gears of War. It could lead to some really intense battles and strategic planning. Also, the idea of Dust being used in the Gears of War universe or vice versa, like using the Imulsion as a power source in RWBY, is quite fascinating.
Another concept is the exploration of different character arcs. Maybe a minor character in the original Naruto gets a major role in the fanfiction, like how a side - character ninja might rise to lead a rebellion against a corrupt village leader in the 'naruto total war fanfiction' universe. It gives a chance to expand on characters that didn't have much spotlight before.
