One possible plotline could be Loki using Percy for his own mischievous ends. Maybe Loki wants to cause chaos in Percy's world, so he takes control of Percy and makes him do things that disrupt the normal order, like causing trouble at Camp Half - Blood.
I'm not sure of specific 'Percy controlled by Loki' fanfictions off the top of my head. You could try searching on popular fanfiction websites like Archive of Our Own (AO3). There might be some interesting stories there that explore this unique concept.
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.
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.
Tony might try to help Loki break free from the control. This could lead to a new alliance between them, which would be quite different from their usual relationship. They could then team up against the force that is controlling Loki.
A notable 'Percy Jackson Loki' fanfiction is 'When Percy Meets Loki'. This story delves deep into how their personalities clash and then gradually come to respect one another. The writer creates a detailed world where the two characters must navigate through various challenges together, making it an engaging read.
One interesting Percy, brother of Loki fanfiction could be 'Percy's Asgardian Adventure'. In it, Percy discovers his relation to Loki and has to navigate the complex politics of Asgard. Another one might be 'Percy and Loki's Bond', which focuses on how their brotherly bond develops over time, despite the differences in their upbringing. There's also 'Percy in Loki's Shadow', where Percy struggles to come out from under Loki's well - known reputation in Asgard.
Perhaps Percy has proven his worth through his unwavering loyalty and courage. Loki, who is used to seeing self - serving and deceitful behavior among the gods and mortals, is impressed by Percy's pure - heartedness. His actions of always protecting his friends and standing up for what is right might make Loki feel that he is worthy of respect, leading to Loki bowing to him.
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.
Maybe Tony notices some unusual behavior in Loki. For example, Loki might be acting against his normal self - not as cunning or devious as he usually is. His actions could seem more robotic or forced, which makes Tony suspect that he's being controlled.
