The 'what - if' scenario of Bardock becoming a main character instead of Goku. This allows for a whole new perspective on the Dragon Ball universe. We could see Bardock's take on dealing with the various villains and his own moral code in handling different situations.
Well, one aspect of Dragon Ball Super Bardock fanfiction could be exploring his backstory further. Maybe delving into his early days on Planet Vegeta and his relationships with other Saiyans. It could also show his potential power growth that we didn't see in the original series.
In this fanfiction scenario, it could be an extremely emotional encounter. Goku, who has grown so much in Dragon Ball Super, finally meeting his father Bardock. Maybe Bardock gets to see how his son has not only become a powerful Saiyan but also a protector of Earth. It could lead to some interesting exchanges about Saiyan heritage and the future of the Saiyan race.
Well, in many fanfictions, a common storyline is Bardock using his Super Saiyan powers to change the fate of Planet Vegeta. He might fight against Frieza's forces in a more epic way. Also, there are stories where he trains other Saiyans to unlock their Super Saiyan potential. It gives a different perspective on the Saiyan race's development. And then there are those that show Bardock traveling through time as a Super Saiyan, which can lead to some really interesting crossovers with other Dragon Ball Z timelines.
A popular version of Bardock in fanfiction is the one who has a premonition of the destruction of the Saiyans much earlier. This Bardock then tries to take actions to prevent it, like gathering other Saiyans who might be sympathetic to his cause. It makes him a hero figure right from the start, rather than just a victim of Frieza's wrath as in the original story.
A lot can happen. Goku could show Bardock his new techniques like the Ultra Instinct. Bardock might be proud of his son's growth. They could also have a sparring match where Bardock gets to see how strong Goku has become.
One popular trope is the 'fix - it' story. Fans often write fanfics where a character travels back in time to correct a major event that went wrong in the original series, like preventing the destruction of a planet or the death of a beloved character. Another is the 'alternate timeline' trope. This involves creating a completely different version of the Dragon Ball Super universe through time travel, with different power levels, relationships, and story outcomes. The 'time - loop' trope is also common, where a character is stuck repeating a certain period of time over and over again until they figure out how to break the loop.
Goku is a great character to pair with Bardock. Since Goku is his son, it can create some really emotional and action - packed scenes. They can train together or fight side by side against common enemies. Another good option is Vegeta. Their different personalities as Saiyans can lead to interesting interactions. Bardock's old - school Saiyan ways compared to Vegeta's pride can make for some engaging storylines.
One idea could be that Bardock lives and he manages to escape Frieza's planet - destroying attack. He then travels through space, gathering power and knowledge. Eventually, he could return to Planet Vegeta as a much stronger warrior and lead a rebellion against Frieza. This would completely change the course of the Saiyan history in the Dragon Ball universe.
One great Bardock in Dragon Ball Z fanfiction is often depicted as a fearless and noble Saiyan. He is shown as a warrior who, despite the cruel nature of the Saiyan race at that time, had a sense of honor. In some fanfictions, he manages to break free from the control of Frieza in more creative ways than in the original story, making his character even more complex and interesting.
There could be a 'Dragon Ball Super Bardock fanfic' that focuses on Bardock's relationship with Vegeta. Maybe Bardock somehow gets to interact with Vegeta during the 'Dragon Ball Super' era. He could share his insights about Saiyan pride and the mistakes of the past Saiyan race. This would be a great way to explore both characters deeper and show how Bardock's presence could influence Vegeta's growth.
