Goku Black's presence could create new rivalries. Other fighters who oppose his evil ways would form alliances just to take him down. This would shift the focus from the original tournament goals to dealing with him. And his combat style, which is similar to Goku's but with a dark twist, would make battles against him very difficult for the other contestants.
In fanfiction, Goku Black in the Tournament of Power would change the power balance. He could use his knowledge of Goku's techniques to his advantage. Also, his dark energy might influence the environment of the tournament arena in some strange ways. For example, it could start to corrupt parts of the arena or affect the mental states of nearby fighters. His presence would force the other fighters to adapt their strategies quickly and might even lead to some of them developing new powers or techniques specifically to counter him.
He would add more chaos. Since he's a powerful and unpredictable character, his actions would disrupt the normal flow of the tournament. He might target strong fighters first to gain an advantage.
He would change the power balance. His raw strength and speed could intimidate some opponents. And his strategic thinking would make him a tough opponent to plan against.
Bardock's presence would likely add a new level of intensity. His Saiyan warrior spirit would inspire the other Universe 7 members. He might be more aggressive in his fighting style compared to some of the others, which could either lead to quick victories or put him in risky situations.
The power dynamics would also change in terms of how Goku's friends interact with him. They would be very cautious as they try to figure out if it's really Goku or Baby in control. Goku's power, which was once a source of hope and protection, could now be a threat if Baby is in charge. And if Goku is fighting against Baby's control, his power might be inconsistent or erratic as the two forces struggle within him.
Daenerys in Winterfell would disrupt the existing power dynamics in multiple ways. For one, her very presence as a Targaryen with a claim to the throne challenges the Stark's authority in the North. Her dragons are a huge factor; they could be used to intimidate or be seen as a great asset. This might lead to some characters trying to manipulate her for their own gain. For example, Littlefinger (if he were still alive) might try to play both sides, using Daenerys against the Starks or vice versa. Also, the common people in Winterfell would be divided in their opinions of her, some seeing her as a savior and others as a foreign invader.
He could be more cunning and strategic, constantly plotting against his opponents in the Tournament of Power.
If Broly was in the Tournament of Power, it would have a huge impact on the outcome. His power is extraordinary. He could change the strategies of all the teams. For example, Universe 11 might focus all their efforts on taking Broly out first. This would create openings for other Universe 7 fighters. Also, Broly's berserker - like fighting style could disrupt the order of the battles. He might accidentally destroy parts of the arena, affecting the fighting conditions for everyone. In the end, his presence would make the tournament much more unpredictable and exciting.
Bruce Wayne's presence would likely bring a sense of discipline and high standards. His skills and knowledge are far beyond the average cadet, so he could inspire others to strive for more. For example, in physical training, he'd set new records and make others work harder. Also, his moral compass would influence the academy's culture, making it more about true justice rather than just following orders.
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.
I think Broly could also be a really tough opponent. In his Legendary Super Saiyan form, he has incredible power and his rage - driven fighting style could give Goku SSJ4 a hard time in the Tournament of Power. Broly doesn't hold back and his raw power could potentially overpower Goku if he's not careful.
In fanfiction, Goku Black might have some unique power - ups during the Tournament of Power. He could tap into a new form that's even more menacing than his regular state. This would give him an edge over his opponents and make for some exciting battles. He might also use his wits and manipulation skills to turn the other fighters against each other.
