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.
There could also be other secondary characters that play important roles in the fanfiction. For example, villains or allies that help or hinder Jak and Kyrie's journey. These characters can add more depth and complexity to the story.
Kyrie is another important character. She is usually portrayed as a strong - willed and kind - hearted female character. Her relationship with Jak forms the core of the fanfiction in many cases. And Daxter is also a key character, he is Jak's sidekick, providing comic relief and often getting into trouble which Jak has to get him out of.
Perhaps Jak has to prove himself worthy to Kyrie's family in order to be with her. This could involve him taking on difficult quests and showing his loyalty and courage. Meanwhile, Daxter could be there as a comical sidekick, adding some humor to the story.
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.
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.
Jak is a heroic figure in Jak and Daxter Full Story. He's courageous and bold, taking on powerful enemies without hesitation. He also has a sense of justice that drives him forward. Daxter is a unique character. He's not just a sidekick but a friend with his own quirks. He's talkative, which can be both endearing and annoying at times. His ability to find humor in difficult situations makes him an important part of the duo. Overall, their different personalities complement each other well during their many escapades.
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.
A scientist would be a great character. They could study the unique flora and fauna of the Jak and Daxter world and try to find ways to use their knowledge to help the inhabitants. For example, they might discover a new way to harness eco energy.
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.
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.
