In this fanfiction, it could be about a magical spell that, when cast, starts a process where a variable 'n' in the magical equation is approaching infinity. This causes all sorts of chaos and wonder in the magical world, and the main characters have to find a way to either control or reverse the spell.
Perhaps it could be a story where a group of adventurers explore a realm that is said to have infinite possibilities. They encounter various strange phenomena that seem to be related to the idea of 'n meets infinity', like never - ending mazes or constantly evolving landscapes.
In the fanfiction, the little girl could be in trouble. Maybe some small - time criminals are harassing her in an alley. Venom senses her distress and comes to her rescue. Afterward, the girl is so grateful and tells Venom that he's her favorite anti - hero. Venom is touched by her kindness and lack of fear towards him, and decides to keep an eye on her from a distance to make sure she's always safe.
In a 'bionicle meets human fanfiction', there could be a story where a human scientist creates a device that can open portals to different dimensions. One day, a Bionicle steps through one of these portals into the human world. The human is initially scared but soon realizes that the Bionicle is not a threat. They start to explore each other's worlds together. The Bionicle shows the human his world of high - tech machinery and unique landscapes, while the human shows the Bionicle things like nature on Earth, which the Bionicle has never seen before. As they travel between the two worlds, they also face challenges from both sides. Some Bionicles might not trust the human, and some humans might want to use the Bionicle's technology for their own gain.
A possible plot could be that they meet while on a dangerous mission. Maybe they are both trying to steal some important information from the same evil force. This would lead to an initial mistrust between them as they think the other might be a spy, but then they realize they have a common goal.
One idea could be to have the cartoon versions of the heroes and villains swap powers. For example, Iron Man could end up with Thor's lightning powers and Loki could have access to Captain America's super - soldier strength. This would lead to really unique battles and character development as they struggle to control new abilities.
One idea could be exploring the family dynamics within the Avengers during the Infinity War. For example, how do the different characters who have a sort of family bond, like Tony Stark and Peter Parker, deal with the chaos of the war? Another could be a fanfiction where a superfamily from a different dimension arrives to help in the Infinity War and how they interact with the existing heroes.
One idea could be exploring what if a minor character from the movie got the Infinity Stones instead. For example, a random Asgardian warrior. They might use the power in a completely different way, perhaps trying to restore Asgard rather than the more universal aims Thanos had.
A really interesting plot could be based on the idea of time travel within the context of 'The Avengers Infinity Wars' fanfiction. What if the Avengers found a way to go back in time and change certain events that led to Thanos getting the Infinity Stones? They could try to prevent the destruction of Xandar where the Power Stone was first retrieved, or stop Loki from stealing the Tesseract on Earth, which was a crucial step in Thanos' plan.
One plot idea could be a character from RWBY getting their hands on the Infinity Gauntlet and having to deal with the power corrupting them. For example, Ruby might struggle with the new - found power and how it changes her perception of right and wrong.
One idea could be a crossover where characters from both shows meet in a shared universe. For example, Cory and Topanga from 'Boy Meets World' could meet Riley and Maya from 'Girl Meets World' and they all go on an adventure together in New York City. They could help each other with their personal and relationship problems, sharing their different experiences from their respective shows.
In 'death meets the avengers fanfiction', a possible plot could be that Death is personified as a female figure. She comes to Earth because she's bored in her realm. She starts causing chaos among the Avengers by making their powers malfunction. The Avengers initially think it's a new super - villain but soon realize it's Death. They then have to find a way to either send her back or make a deal with her. Maybe they offer to perform a great deed in exchange for her leaving Earth and their lives alone.
