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.
In some fanfictions, Goku Black has been depicted as having a hidden power reserve. In the Tournament of Power, he could tap into this reserve and achieve a new level of transformation. This new form would give him increased speed, strength, and energy projection. He might use this form to take on multiple strong opponents at once, like the powerful warriors from Universe 7 or other universes. His attacks could become more unpredictable, such as his energy beams changing direction mid - flight to catch his foes off - guard.
Well, clearly Goku from Dragon Ball and Power Girl from DC Comics are the main characters. Goku is known for his Saiyan heritage and his ever - increasing power levels through training. Power Girl, on the other hand, has superhuman strength, flight, and various other powers.
In the 'goku is op and godlike as a baby fanfiction', Goku's power as a baby could be demonstrated in various ways. His senses could be highly developed, allowing him to detect danger or the presence of strong opponents from afar. He may also possess an inherent understanding of combat strategy, despite his young age. This could be due to some sort of genetic or mystical influence. Additionally, his physical abilities such as speed and agility could be far beyond what is normal for a baby. He could move with incredible swiftness and precision, almost like a miniature martial arts master, which is a clear sign of his over - powered and godlike nature.
Hit would also make for a fascinating pairing. Hit is a skilled assassin with time - manipulation abilities. He could be a great foil to Goku Black. Maybe Goku Black tries to outwit Hit in his time - stop techniques, or they could form a temporary alliance based on their mutual desire to eliminate certain opponents in the tournament. There would be a lot of cat - and - mouse action between them.
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.
One interesting plotline could be Goku discovering a new form during the Tournament of Power in the fanfiction. This form might give him an edge over the other powerful opponents.
Vegeta can also be extremely powerful in these fanfictions. He's constantly striving to be stronger than Goku and might gain some new abilities or techniques for the tournament. Another character could be Jiren. In the original Tournament of Power, he was a very tough opponent, and in fanfiction, he might be even more powerful or have some different backstory that makes him a formidable force.
In a Naruto - Goku fusion fanfic, the power - ups could be really exciting. Since Goku has his Zenkai boosts, and Naruto can gain more chakra and power as he progresses in his ninja journey, the fusion might have a new type of growth system. For instance, every time the fusion is in a tough battle, it could gain a permanent boost in strength, speed, and energy. Also, the fusion could potentially access a new form that combines the Super Saiyan transformation and the Nine - Tails' chakra mode for an insanely powerful state.
