In a Goku Black crossover Naruto fanfiction, power levels are a bit tricky to compare. Goku Black comes from a universe where power is measured in ki and he has access to super - saiyan forms which boost his already great strength. Naruto has his own unique power system based on chakra. Initially, Goku Black would seem more powerful as his attacks are more destructive on a large scale. But Naruto has an advantage in his ability to adapt and his connection with the Nine - Tails. Also, Naruto's friends and the entire shinobi world could potentially back him up. So, while Goku Black may start as the more powerful one, in the long run, Naruto's growth potential and the support of his world could make him a strong contender for the most powerful character in this crossover.
In a Goku Naruto crossover, both characters have their own strengths. Goku's physical strength and energy attacks are off the charts. His ability to instantly teleport and sense ki gives him an advantage in combat. Naruto, though, has a unique power system. His connection to the Nine - Tails and his ability to use different types of chakra make him a force to be reckoned with. If we consider a battle, Goku's power might seem greater on the surface. But Naruto has the advantage of being able to surprise his opponents with his ninjutsu and clones. Also, Naruto has a strong willpower that has allowed him to overcome many tough situations, which could play a role in a fight against Goku.
Goku is known for his raw power and his ability to constantly increase his strength through training and battles. He can blow up planets with his attacks in his more powerful forms. Naruto, on the other hand, has the power of the Nine - Tailed Fox and his own unique ninja skills. But if we consider the fact that Goku can move at speeds close to the speed of light and has energy attacks that can obliterate entire solar systems, he might seem stronger. However, Naruto's ability to use shadow clones to outnumber his opponents and his Sage Mode which gives him enhanced perception and strength can't be ignored. It really depends on the situation and how the author of the fanfiction writes the encounter.
A plot could involve Goku Black arriving in the Naruto world during a time of great unrest, like when the Akatsuki is causing chaos. He sees the shinobi as weaklings compared to his Saiyan strength. However, Naruto, with his Sage Mode and Nine - Tails chakra, manages to hold his ground against Goku Black in a first encounter. This catches Goku Black's attention, and he decides to study these 'new' powers. Meanwhile, the shinobi villages must decide whether to see Goku Black as a potential threat or an opportunity to learn from his power. Eventually, they could team up to fight a greater evil that emerges due to Goku Black's presence in their world.
Sasuke could also oppose Black Goku. With his Sharingan and Rinnegan, Sasuke has a wide range of powerful abilities. He is also very intelligent and strategic. Sasuke would likely see Black Goku as a threat to the balance of power in the Naruto universe and would step in to fight him, especially if it involved protecting his friends or the ninja world in general.
It could be insanely powerful. Goku already has incredible power levels, and Goku Black is no slouch either. When they fuse, it's like combining two nuclear reactors. Their power could be so great that they could effortlessly destroy planets just by flexing their newfound power. They might be able to reach Super Saiyan forms that are far beyond what we've seen in the official series, with power levels that are basically off the scale.
Sesshomaru could also be a very powerful character in this crossover. He has his own powerful sword, Bakusaiga, and his inhuman strength and speed. He is very experienced in combat against demons. Compared to Naruto's friends like Sakura, Sesshomaru would likely be much more powerful in terms of raw strength and combat ability. But Sakura has her own medical ninjutsu and superhuman strength when she releases her inner power, which could also be useful in different situations.
It's really hard to say. Naruto in his strongest form, like when he has the power of all the tailed beasts, is extremely powerful. He has incredible strength, speed, and the ability to use a vast array of jutsu. However, Aang in the Avatar state has access to all four elements and can be a formidable opponent. If we consider the Avatar state's spiritual connection, it could give Aang an edge in a battle of wills.
It's hard to say for sure. Goku is extremely powerful with his Super Saiyan forms and god - like powers. But in the DC universe, there are also incredibly strong characters like Darkseid. Darkseid has omega beams and is a near - omnipotent being. However, Goku's ability to constantly increase his power level might give him an edge in a long - drawn - out battle.
One possible fanfiction could involve Goku Black's unique powers in the Naruto universe. Maybe he could be a powerful antagonist, using his ki-based attacks against the ninja. Naruto, with his never - give - up attitude, would likely try to find a way to defeat him through his own jutsu and the power of friendship.
One common theme is power struggles. Since Black Goku is a very powerful character, when he crosses over, there are often battles to determine who is the strongest in the new combined universe.
