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.
Well, the story of Barbie and Jak might be a really sweet one. Maybe they met at a party. Jak was attracted by Barbie's charm immediately. He started to talk to her and found that they had a lot in common. They then began to go on dates, like going to the movies or having picnics in the park.
They might love fanfiction because it offers new and exciting adventures for them. Fanfiction can take their story in directions that the original might not have explored.
A common theme is adventure. Since the Jak and Keira characters are from a game with a lot of action, fanfictions often continue their adventures together. They might go on quests to save their world or discover new lands.
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.
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.
Maybe a fanfiction that delves into their backstories more. It could show how they first met and the early days of their relationship, like how they slowly grew to trust and rely on each other.
Common themes include adventure. Since they live in a world full of danger, their love is intertwined with their adventures. Also, there's the theme of redemption. Jak has a dark past in some versions, and Keira's love helps him find redemption. And the theme of hope. Their love gives them hope in a world that seems doomed.
