Adventure time:Reborn as finn

In this fanfiction, an exciting plot could be Si being reborn as Finn but with some of his own memories intact. He then tries to find a way to merge his old self with Finn's heroic identity. Along the way, he might meet Jake and they could go on adventures together. Si could also have to deal with the moral dilemmas that Finn sometimes faces, like whether to help a villain who seems to have a good side.

Obviously, Jake would be one of the main characters Si, reborn as Finn, would interact with. They would go on all sorts of wacky adventures together. Also, Princess Bubblegum. Since Finn often helps her with various problems in Ooo, Si would also be involved in those situations, like dealing with the Candy Kingdom's threats.

In some Adventure Time fanfictions, Finn might be betrayed by a character he trusted deeply, like Jake. For example, Jake could make a deal that goes against Finn's values in order to protect the Candy Kingdom, leaving Finn feeling betrayed as he sees it as a moral compromise. Another instance could be a new character in the fanfiction who befriends Finn only to steal his magic sword for their own gain.

Well, Finn's real story is that he's a hero in the Land of Ooo. He's constantly on the move, exploring different parts of the land. He was raised in a rather unique environment, which has made him brave and curious. Finn has this unwavering sense of justice. For example, he'll always stand up to bullies like the Lich. His relationship with Jake is a big part of his story too. They're like brothers, always having each other's backs in any dangerous situation that they encounter during their adventures.

One idea could be that Finn is kidnapped by an old enemy who wants to use him as a bargaining chip against Princess Bubblegum. Maybe they demand her to give up the Candy Kingdom in exchange for Finn's safe return.

One possible scenario in this fanfiction could be that Finn's transformation into a vampire brings out a whole new side of his personality. He might struggle with his newfound thirst for blood while still trying to uphold his heroic values. Maybe he teams up with Marceline, who is already a vampire, and she teaches him how to control his urges.

He might meet some of the more reclusive characters in Ooo that we don't usually see in the show. Maybe a hermit - like wizard who gives him some cryptic advice.

Finn's parents in Adventure Time fanfiction can have really interesting backstories. Maybe his mother was part of an ancient race that was hunted, and she hid Finn to protect him from the same fate. His father might have been a member of the human tribe that was scattered across the Land of Ooo. Fanfiction allows for different interpretations of how Finn came to be alone as a baby. It can be really exciting to read different authors' ideas on this.

One common theme is friendship. Finn is all about his friends in the show, and in fanfics, his relationships with Jake, Princess Bubblegum, and others are often explored further. Another theme is self - discovery. Finn is constantly growing and learning about himself, and fanfics often take this aspect and expand on it. For example, in some fanfics, he discovers new powers or abilities that make him question who he really is.

In Adventure Time, Finn's love story is quite complex. He has strong feelings for Princess Bubblegum. Finn's love for her is pure and often drives his actions. For example, he would go on many adventures to protect her kingdom. However, their relationship also has its challenges, like when Bubblegum's responsibilities as a princess sometimes come between them.
