One can expect Piccolo to be in a match against a Namekian - like being from another universe. There could also be team battles where characters from different universes form alliances or oppose each other in interesting combinations.
In the fanfiction, it's possible to see Android 17 from Universe 7 take on a similar - type android from another universe. Also, Frieza might be matched with a tyrant - like character from a different multiverse.
Goten. He's often overlooked but has a lot of potential. In the fanfiction, he could have trained in secret and developed new techniques that would shock everyone and lead him to victory.
One interesting storyline could be a character from an alternate universe who has a unique power that no one in the main Dragon Ball universe has seen before. This character could enter the tournament and completely disrupt the expected power balance, leading to unexpected alliances and rivalries among the fighters.
Vegeta is also highly popular. Fans love seeing him compete in the tournament, especially when he has to deal with opponents who are just as prideful as he is. His development from a villain to a hero and his complex relationship with Goku add depth to his character in these fanfictions.
One interesting concept could be the different power levels and transformations that characters might have in the multiverse. For example, a fanfiction might explore a version of Goku where he has an entirely new form that combines the powers of different Saiyan lineages from various universes. Another concept could be the crossovers between characters from different universes within the Dragon Ball multiverse. This could lead to unique battles and alliances.
One of the interesting power - ups could be his Ultra Instinct form. In fanfiction, it might be further enhanced, like having different levels that are not shown in the original. For example, he could have an Ultra Instinct - Kaioken combination which would be extremely powerful.
Gotenks is quite popular in Dragon Ball Super Multiverse Fanfiction. The idea of his super - powerful and often - comical antics being expanded in the multiverse is appealing. Also, Whis is a popular character. His vast knowledge and his role as Beerus' attendant can be explored in many different ways in the multiverse. He could be training characters from different universes or involved in some kind of multiverse - spanning mystery. Trunks is another popular one, especially when his time - traveling abilities are combined with the multiverse concept.
One interesting match - up could be Goku vs Liu Kang. Goku is known for his incredible strength and speed, while Liu Kang is a highly skilled martial artist with fire - based powers. Another great match - up would be Vegeta and Scorpion. Vegeta's prideful and aggressive fighting style against Scorpion's vengeful and stealthy attacks would make for an exciting fight. Also, Piccolo vs Sub - Zero could be cool, as Piccolo has his energy attacks and Sub - Zero has his ice powers.
Once upon a time in the Dragon Ball Z universe, a grand tournament was announced. Goku, excited as always, was the first to sign up. Vegeta, not wanting to be outdone, followed suit. The day of the tournament arrived. Fighters from all over the galaxy gathered. The first fight was between Goku and a mysterious new fighter. Goku quickly transformed into Super Saiyan. He threw a flurry of punches and kicks, but the new fighter was surprisingly agile. In the end, Goku won with his signature Kamehameha wave.
One interesting plot twist could be a character who was thought to be weak suddenly unlocking a new and extremely powerful form during the Tournament of Power. This form gives them an edge over stronger opponents and changes the whole dynamic of the battles.
Perhaps a story where a previously unknown fighter enters the Tournament of Power. This fighter has been training in seclusion and has powers that are a combination of different techniques from various universes. They start off as an underdog but quickly become a force to be reckoned with, making allies and enemies along the way.
