A more emotional plot idea could be August Walker falling in love, which would be very complex as his dangerous lifestyle and secrets would constantly be at odds with his feelings. This could lead to a lot of internal conflict and difficult decisions.
The OC could be a brilliant hacker who is forced to work with August Walker. The OC is constantly trying to outwit Walker and his team while also having to deal with the dangerous situations they get into. This could lead to a lot of tense moments and a slow - burning relationship as they learn to trust each other.
One plot idea could be that the chibi Allen Walker discovers a hidden power within himself while on a simple mission. Maybe he stumbles upon a mysterious artifact that unlocks a new form of his Innocence. Another idea is that he gets transported to a parallel world where everything is in miniature like him, but there are different rules and he has to figure out how to get back. And also, a plot where he befriends a group of other chibi exorcists and they form a special team to take on a powerful Akuma that no one else could defeat.
I think Ethan Hunt could be a great character to pair with August Walker. Their different moral compasses and methods would create a lot of interesting interactions and power struggles.
One idea could be a story where the Mandalorian has to team up with an old enemy to fight a new, greater threat. Maybe a powerful Sith Lord emerges and they have to put aside their differences.
One idea could be exploring a different origin for Toothless. Maybe he was part of an ancient dragon tribe that was thought to be extinct. Another could be a story where Hiccup discovers a new dragon species that has unique abilities and forms an alliance with them. A third idea is a time - travel fan fiction where Hiccup goes back in time to prevent a great dragon war from ever starting.
A great plot for Warframe fan fiction could be a Tenno getting trapped in a parallel dimension where the rules of the Origin System are all messed up. They have to find a way back while dealing with strange versions of familiar enemies. Or perhaps a story about a Tenno who discovers a hidden Orokin vault that contains not only powerful weapons but also a secret that could change the balance of power in the Origin System. Also, a plot about a Tenno's struggle to control a newly acquired and extremely powerful Warframe that has a mind of its own could be really engaging.
Well, you could have a survivor fan fiction where a contestant has a hidden skill, like being able to communicate with animals on the island. This could give them an edge in finding food and avoiding danger. Or perhaps a story where there's a traitor within the group, someone who is secretly working with the show's producers to create more drama. Also, a plot where the survivors find a map that leads to a hidden part of the island with a bountiful supply of food and shelter.
One idea could be that the Ghostbusters discover a new type of ghost that can possess technology. So they have to find a way to stop it from taking over all the electronics in the city. It would be a race against time as the city starts to descend into chaos with machines going haywire.
One idea could be a story where a minor character from the game gets a chance to become a hero. For example, a low - level soldier who discovers a hidden power within himself and uses it to save his comrades during a crucial battle.
One interesting plot idea could be exploring what would happen if Aladdin's three wishes had unforeseen consequences that affected not just him but the whole city. For example, a wish for wealth might lead to an economic imbalance.
