Jiren's back story is that he comes from a race that was nearly wiped out. He was left as one of the few survivors. His experiences made him extremely strong and he dedicated himself to training hard to become the mightiest warrior, believing that only strength can protect and bring justice.
Jiren's back story in Dragon Ball Super is about survival. His race was decimated, leaving him alone. He then found purpose in the Pride Troopers, training hard to be strong because of what he had lost.
Dragon Ball Super vs GT in fanfiction can lead to some really interesting character developments. The different timelines and power systems in both series offer a lot of room for creativity. In some fanfictions, the younger characters from Super might meet their older counterparts from GT. This can create a contrast in personalities and fighting styles. For example, Trunks in Super is more used to the modern power-ups and technology, while Trunks in GT has a more 'old - school' approach. Fanfic authors often use these differences to create engaging stories that explore not only the battles between the two series but also the underlying themes and character growth.
Saitama would win. He has shown incredible strength with just one punch. His power seems limitless, and in a fanfiction scenario, his simplicity and raw power would likely overpower Jiren's more complex abilities.
One possible plot twist could be that Jiren discovers a way to nullify Saitama's strength. Maybe he finds some sort of energy - draining technique that weakens Saitama over time. Another could be that Saitama holds back for some reason, like he wants to see the full extent of Jiren's power, and in doing so, he gets into a real struggle.
In this fanfiction, Goku vs Jiren is likely to be an epic battle. Goku's power with the Universe's Watch might bring new and unexpected abilities. Jiren, on the other hand, is an extremely powerful opponent. The fight could involve intense energy blasts, high - speed combat, and strategic maneuvers. It might also explore the growth of Goku's character and his newfound power in relation to Jiren's unwavering strength.
One idea could be that Hit is sent to the RWBY universe on a mission. He could encounter the various teams and their unique abilities. Maybe he has to team up with Ruby and the others to fight a common enemy that is causing chaos in both the Dragon Ball and RWBY worlds, like a powerful being that can manipulate time and space.
It's really hard to say. Goku has his Super Saiyan forms which give him incredible power boosts. But Superman has super strength, heat vision, and is nearly invulnerable. In a short fight, Superman might have the edge due to his instant powers like flight and super strength without having to power up. But if Goku manages to reach his higher Super Saiyan forms and uses techniques like the Spirit Bomb, he could potentially defeat Superman.
It's hard to say. Goku in Dragon Ball Super has Ultra Instinct which gives him incredible speed and reflexes. But in GT, his Super Saiyan 4 form is also extremely powerful. However, if we consider the fact that Ultra Instinct seems to be a more refined and spiritual form of power, it might give Goku in Super an edge. But then again, the Super Saiyan 4 form has its own advantages like the combination of Saiyan and Great Ape power.
Another possible ending is that Gohan sacrifices himself to defeat Cell. He could use a self - destructive move that not only takes out Cell but also costs Gohan his life. This would be a very dramatic and tragic ending, but it would also show Gohan's selfless heroism.
