Well, a great plot twist might be that the lie detector is not just detecting lies but also hidden emotions. So, when a character is questioned, it reveals their deepest fears or loves which they were trying to hide. This could lead to some really unexpected alliances or betrayals within the Agents of Shield team. Also, it could be that the lie detector is part of an alien technology that has a mind of its own and starts influencing the agents' decisions without them realizing it.
One interesting plot twist could be that the lie detector is actually malfunctioning but gives correct results in a completely random and unexpected way. For example, it might say someone is lying when they're actually telling the truth about a minor detail, but that minor detail leads to a major discovery. Another twist could be that the person operating the lie detector has an ulterior motive and is manipulating the results to frame someone. They could be using it as a tool to further their own secret agenda within S.H.I.E.L.D.
A possible plot twist in an Agents of Shield lie detector fanfic could be that the lie detector is a test by a higher - up in S.H.I.E.L.D. to see who can be trusted. But the real twist is that the higher - up is actually a double agent and is using the results to weed out the agents who are getting too close to uncovering their true identity. The lie detector then becomes a key element in a much larger conspiracy within the organization, and the agents have to figure out how to expose the truth without relying on the seemingly reliable lie detector.
The lie detector can create a lot of tension. If it shows that a character is lying, others might start to distrust them. For example, if a team member is wrongly shown as lying about their whereabouts during a mission, their teammates could become suspicious. This could lead to a rift in their relationship until the truth is uncovered.
One interesting plot twist could be a character who was thought to be dead actually returns but with new powers. This would completely change the dynamics within the team. They would have to figure out if they can trust this person again and how to use their new powers to their advantage.
One idea could be a story where a new villain emerges who has the ability to manipulate time. The Agents of Shield and the Avengers have to work together to stop this villain before he changes history in a way that destroys the world. Another plot could involve an agent from Shield who discovers a long - lost relative who has superpowers and is being hunted by an evil organization. The agent has to protect their relative while also dealing with the implications of this newfound family member within the context of their work with Shield and the Avengers.
A fanfic storyline could focus on an alternate universe where the Agents of Shield are not a government - affiliated organization but rather a group of rebels fighting against a tyrannical regime that has taken over the world. They would have to use their skills in a different way and form new alliances.
A really interesting plot idea could be that Lincoln starts to have visions while in containment. These visions lead him to believe that there is a greater threat approaching the Agents of Shield. He then has to convince the others, who are skeptical at first, that they need to prepare. He could use his time in containment to train himself mentally to face this new threat, and the story could show his growth from a reluctant captive to a determined hero.
Perhaps there could be a time - travel related plot. A device is accidentally activated in a S.H.I.E.L.D. lab that sends some Agents and Avengers back in time. They end up in a crucial moment in history, like during World War II. There, they meet younger versions of some of the Avengers. They have to work together without changing the timeline too much while also finding a way back to their own time.
One possible plot could be that the cat is actually a shape - shifted alien or a magical creature. The lance could be a key item that has the power to either control or protect the cat. The Agents of Shield discover this strange combination and have to figure out how to deal with it, whether it's a threat or something that could be used to their advantage.
One idea could be a fanfic where Miles has a secret power that he discovers while on a mission with the Agents of Shield. This power could be something that changes the dynamic of the team and how they operate.
A great fanfic idea could be about an old enemy from the Agents of Shield's past coming back and the Avengers being brought in to help. It could involve a lot of mystery, action, and the building of new relationships between the two groups.
Well, a simple plot could be that a mermaid is accidentally caught in a portal created by some alien tech that the Agents of Shield are studying. She then finds herself in a world she doesn't understand, and the agents have to figure out how to get her back home. At the same time, they discover that her presence is causing some strange energy fluctuations that could be dangerous.
