It could be a genetic mutation in the fanfic's storyline. Some strange event or factor could have caused a change in Bardock's genes, making it possible for him to become Super Saiyan. This genetic change might be related to some ancient Saiyan lore or a new element introduced in the fanfic's universe.
The change of Bardock becoming Super Saiyan in the Vegeta fanfic can completely rewrite Saiyan history. It could start a new era of Saiyan pride and power. Bardock, with his new - found Super Saiyan form, might be able to teach the younger Saiyans about the transformation. This could lead to a more united Saiyan race, as they all work towards achieving the Super Saiyan state. It might also mean that they are not as easily defeated by Frieza, as they have a stronger force to oppose him. This could result in a different galactic power structure, with the Saiyans being a more dominant force.
Another theme could be loyalty. Bardock might be loyal to the true potential of the Saiyan race while King Vegeta is loyal to the existing power structure. This difference in loyalty can create a great conflict in the fanfic. Also, there could be a theme of social change. As Bardock may represent the underclass Saiyans who want a change, and King Vegeta is the symbol of the old regime.
The Saiyan race would likely face more destruction and chaos. Without Bardock saving Vegeta, the leadership of the Saiyans might be in disarray. The power structure could crumble as Vegeta was an important figure. Enemies of the Saiyans could take advantage of this situation and launch more attacks. It could also lead to a loss of hope among the remaining Saiyans as one of their strongest leaders is gone.
There's a fanfic where Bardock becomes a Super Saiyan God in an alternate universe. Here, he uses this power to try and change the fate of the Saiyans. The story could show how his newfound power affects his relationships with other characters like Vegeta and Goku, and how he might use it to stand up against the likes of Frieza in a different way than in the original story.
The fanfic 'Bardock: The Super Saiyan God's Redemption' is quite good. In it, Bardock, as a Super Saiyan God, has to atone for the past sins of the Saiyan race. He travels across the universe, helping those who were once oppressed by the Saiyans. It has an interesting take on Bardock's character as he tries to rewrite the Saiyan legacy through his actions as a Super Saiyan God.
Yes, he does. Vegeta achieves the Super Saiyan God form in the manga.
Yes, he did. Vegeta achieved the Super Saiyan God form in the manga.
One possible reason could be some sort of magical or energy - based interference. Maybe an enemy has cast a spell that locks his form. Another reason might be that his body has reached its limit in terms of evolution for the time being, and it needs some special trigger to break free from being stuck.
Definitely. Fanfiction is all about creativity and bending the rules. Since the super saiyan concept comes from Dragon Ball and Harry Potter is from a different fictional world, in fanfic, these two can be mashed up. Writers can come up with all kinds of explanations for how Harry Potter gets the super saiyan transformation, like some kind of magical - energy - dragon - ball - type of thing.
Another plot could be that a mysterious entity bestows the power of Super Saiyan Blue on Naruto. He then has to keep it a secret from his friends and village while also using it to protect them from a new and powerful enemy. This would create a lot of internal conflict for Naruto as he tries to balance secrecy and heroism.
