Goku in the manga doesn't hit a power level of 8000. The power escalation in the story doesn't go that high for him. There are various factors and story arcs that determine his power growth, but 8000 isn't one of them.
Obviously, Goku is one of the main characters. Since it's about him being born with a high power level. And his parents might also be important characters as they would be related to his birth and the discovery of his high power level. Maybe there are also some Saiyan elders or trainers who play a role in his life as they would be interested in his power.
In the context of this fanfiction, his high - born power level would have a huge impact on his early days. He may grow up faster in terms of physical strength and combat skills. Since he's born with such power, he might not face the same challenges as other Saiyans in developing basic abilities. However, this could also lead to overconfidence. And perhaps he has to deal with the burden of high expectations from his community at a very young age. He might be constantly pushed to test his limits, which could be both a good and a bad thing for his development.
Goku's power is measured in different forms and levels in his universe. When it comes to Legendary Pokemon, some of them have the ability to control elements like time and space. In a fanfic, Goku in his Super Saiyan Blue form might be able to match the power of a Legendary Pokemon like Palkia, which has power over space. But it also depends on the situation. If Goku is in an environment where his Ki attacks are less effective, like in a dimension where psychic powers are dominant, he might have a harder time against a Legendary Pokemon like Lugia. Overall, it's a complex comparison as their powers are quite different in nature.
Well, Goku's power level progression could be different in that he might be more in control of it. Since the head injury had some impact on his psyche, without it, he could have a more calculated approach to increasing his power. He might not rely as much on the Kaioken technique, which was developed in part due to his need to overcome limitations caused by his injury - affected development. Instead, he could focus more on pure Saiyan power - up methods like the Great Ape transformation and evolving it further.
In a 'Goku vs Beerus' fanfiction, it's really hard to say who would win. It could depend on how the author wants to write it. If the author wants to show Goku's growth, Goku might win through some new transformation or power - up. But Beerus is a powerful God of Destruction, so he also has a great chance of winning.
It's really hard to say. Goku has his amazing fighting abilities and power-ups. But the Avengers have a lot of different powers and strategies. If the fight takes place in the Marvel Universe, the Avengers might have some home - field advantage. However, Goku's adaptability and his ability to quickly learn in battle could give him the upper hand. Maybe it would end in a draw if both sides respect each other's power and stop the fight before it goes too far.
In a 'Goku vs Avengers' fanfiction, Goku's extreme power levels would be a major factor. His Super Saiyan forms could potentially overpower many of the Avengers. However, the Avengers have their own unique skills and teamwork. Iron Man could use his high - tech suits to analyze Goku and try to find weaknesses. Captain America would lead the team in terms of strategy. But Goku's speed and strength might be too much for them to handle in the end.
