The Jak and Daxter story does have an end. However, fans often imagine what could happen next or create their own continuation scenarios in their minds.
The Precursors are very important in the Jak and Daxter universe, and including them in a crossover fanfiction could add a whole new level of depth. They could be the key to understanding the new world they cross into, or perhaps they have a hidden agenda that Jak and Daxter have to figure out. Also, the Metal Heads could be included in a more action - packed crossover, where they pose a threat not only in their own world but also in the crossed - over world.
In Jak and Daxter fanfiction, a normal human could also be a source of help. Maybe they provide shelter or food to Jak and Daxter during their travels. They could be the ones who give important information about the secrets of the land, like the location of a hidden Precursor artifact or a dangerous enemy's lair. Since they are normal humans, they might not have the special abilities of Jak and Daxter, but their local knowledge can be invaluable.
There might be a fanfiction where Daxter gains the ability to use chakra. He tries to learn ninjutsu from Naruto. It would be a humorous story as Daxter is a small ottsel and his attempts at using powerful ninja techniques could lead to all sorts of comical situations. Like when he tries to do a Rasengan and just ends up spinning in circles.
Naruto and Jak make a great pair. Naruto's optimism and determination combined with Jak's more brooding and powerful nature can create a great dynamic. They can learn from each other's strengths and weaknesses.
One interesting Jak and Daxter human fanfiction could be about Jak's origin story before he became the hero we know. It might explore his early life in Haven City, his relationships with other characters in a more in - depth human - like way. For example, how he met Daxter and formed that unbreakable bond.
One idea could be a human from our world getting mysteriously transported into the Jak and Daxter universe. They could start off as a confused bystander but gradually learn the ways of that world and end up helping Jak and Daxter on one of their quests. Maybe they have some unique knowledge from our world, like basic science concepts, that can be applied in unexpected ways in the game's world.
One idea could be that Jak and Daxter end up in a different game world, like a medieval fantasy realm. They have to use their skills in a new way, for example, Jak's agility to climb the tall towers in the fantasy land and Daxter's small size to sneak into places. Another could be a crossover with a sci - fi world where they encounter advanced technology and have to figure out how to work with it. Maybe they meet alien species and have to team up with them to save both their own world and the new one.
Well, obviously Jak and Kyrie are the main characters. Jak is often depicted as a brave and strong hero with his own set of skills and abilities. He has a complex past which can be explored in the fanfiction.
They might interact by forming friendships. A normal human could befriend Jak and Daxter, and in turn, be included in their adventures. For instance, they could join in the exploration of ancient ruins. They can offer different perspectives based on their human experiences, which can be useful in solving puzzles or dealing with tricky situations. Also, normal humans could interact by asking for help. If there is a problem in their village, like a group of bandits causing trouble, they would seek Jak and Daxter's assistance.
