The reader could find themselves in the middle of the power dynamics between Zim and Tallest Red. For example, Zim might try to impress the Tallest Red by using the reader in some way, like showing off a new experiment he's doing on the reader. And Tallest Red could either be impressed or disappointed, which would then affect how Zim treats the reader.
Perhaps the reader is from a planet that has some valuable resource. Zim wants to take over that planet through the reader, while Tallest Red wants to negotiate a trade deal. The fanfiction could explore the different approaches of Zim (more aggressive and underhanded) and Tallest Red (more diplomatic, but still self - serving) in dealing with the reader and the situation. It could also show how the reader tries to outwit both of them to protect their home planet.
In the fanfiction, the reader might start off as a fan of Invader Zim's 'antics'. They follow Zim around, much to the annoyance of Tallest Red who thinks the reader is getting in the way. But as the story progresses, the reader realizes the true nature of the Irken Empire and has to decide whether to side with Zim, Tallest Red, or try to find a third way to stop the Irken's potentially harmful plans.
One type of fanfiction could involve the reader being an unwitting accomplice in one of Invader Zim's crazy schemes while Tallest Red is observing from afar, amused by the chaos. Maybe the reader is a human who has some unique ability that Zim wants to use for his own purposes, and Tallest Red is just there to see how it all unfolds.
In this fanfiction, Dib could find himself in a situation where he has to rely on his wits more than ever. When meeting the Tallest, he may discover some secrets about the Irken race that could change the whole dynamic of his fight against Zim. The Tallest might underestimate Dib at first, seeing him as just a human child. But Dib, being Dib, would use this to his advantage. Zim would be his usual self, trying to prove his worth to the Tallest while also trying to stop Dib from ruining his plans. It could be a really interesting exploration of the characters' relationships and the power dynamics in the Invader Zim universe.
One common theme could be the exploration of an unlikely relationship. Given Zim's chaotic nature and the Tallest Red's position in the Irken hierarchy, their interactions can lead to stories about breaking social norms within the Irken world.
