Finn might initially go into denial. He could keep expecting Jake to just pop back up like he always does. Then he'd probably get angry, at himself or at whatever caused Jake's death. Eventually, he'd start to accept it and try to honor Jake's memory by being a better hero.
One interesting fanfiction could be about Finn and Jake going on a quest to a mysterious new land that wasn't explored in the show. Maybe they encounter a new type of magical creature that challenges their friendship and they have to work together to overcome it.

You can start by checking out popular fanfiction websites like Archive of Our Own. Just type in 'Adventure Time Finn x Jake' in the search bar and you'll get a list of relevant stories. Look for ones with high ratings and a lot of positive reviews.
First, think about the characters. Know Finn's adventurous spirit and Jake's laid - back but loyal nature. Then, come up with an interesting plot. It could be something as simple as them finding a lost treasure in the Land of Ooo. Next, write in a style that matches the show, with a bit of humor and lots of action.
The Fire Kingdom's Flame Princess could be an ally too. Her mastery over fire could complement Finn's powers in combat situations. Also, the various magical creatures in Ooo, like the gnomes or the fairies, could band together and support Finn. They might have their own ancient knowledge or magic that could be useful to Finn in his adventures with his godlike powers. Finn's kindness towards them in the past might make them more inclined to help him out.
One aspect of 'Adventure Time Finn Alone Fanfiction' could be exploring Finn's character development in isolation. Finn is usually a very social character in the main series, so seeing him alone can show a different side of his personality, like his self - reliance and how he copes with solitude.
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.
