In this fanfic, Thanos could be using Loki as a pawn in a much larger scheme. Loki, who is now controlled, might be used to start a war between different realms. However, Loki's own cunning nature and his relationships, like his complex relationship with Thor, could come into play. Thor might notice that something is off with Loki and try to break Thanos' control over him. This could lead to a series of events where Loki slowly regains his free will and turns against Thanos in the end.
Well, one possible plot could be that Thanos uses his mind - controlling powers on Loki to make him steal powerful artifacts for his collection. Loki, being under Thanos' control, has to go against his own nature at times. For example, he might have to target Asgardian relics that he would otherwise protect.
One possible plot could be that Thanos sees Loki as a tool that has failed him. So, he subjects Loki to various forms of physical and mental abuse to break his spirit. Loki, being a survivor, tries to find ways to outwit Thanos even in his weakened state.
Loki would likely lose his usual sense of self - determination. He's normally a character who has his own plans and motives, but under Thanos' control, he would be more like a puppet. His actions would be dictated by Thanos rather than his own desires.
Loki and Thanos are the central figures. However, characters from Loki's family such as Thor could also be significant. Thor might notice the changes in Loki and try to rescue him from Thanos' control. Additionally, characters like Heimdall, who has the ability to see across the realms, could be involved in detecting Loki's unusual behavior and Thanos' influence.
Well, perhaps in this fanfiction, Loki is cursed to be attached to Thanos' legs for a period of time. This forces them to work together in a very strange way. Loki tries to use his wits to find a way to break the curse, while Thanos is frustrated by Loki's constant attempts at trickery. Along the way, they might encounter other characters from the Marvel universe who are both amused and confused by their situation.
In fanfiction, Loki's time with Thanos could involve Loki trying to outwit Thanos. Maybe he's forced to do Thanos' bidding at first but secretly plans to undermine him. He could be gathering information about Thanos' plans and weaknesses.
Well, it could be something like Thanos becomes intrigued by Loki's legs for some strange, otherworldly reason. Maybe Loki has some sort of magic or power that is centered around his legs that Thanos wants to possess or control.
Power is a common theme. Thanos is extremely powerful and Loki is always seeking more power, so fanfics often explore how they interact in terms of power - whether it's a power struggle or a shared pursuit of power.
The plot could start with Lysandre finding a way to gain control over Ash, perhaps through some new form of technology or a mysterious power. Then Ash is made to do Lysandre's bidding, like stealing Pokémon or sabotaging other trainers. As the story progresses, Ash's friends might notice his strange behavior and start to investigate.
In this fanfic, Naruto being the son of Thanos could lead to a whole new power dynamic in the Naruto universe. His powers could be a blend of Naruto's chakra abilities and Thanos' strength and reality - warping powers. He may be in a constant battle within himself, as Naruto's values of friendship and protecting the village conflict with the more self - serving and power - hungry aspects of Thanos' nature. He might have to find a way to reconcile these two sides to become a true hero in his own right.
