Goku would be a great addition. His experience and power could serve as a mentor to Shallot or as a powerful ally in battles. Also, Vegeta could bring his prideful and powerful presence, creating interesting dynamics with Shallot.
One interesting fanfiction could be about Shallot's journey to unlock a new super form. He might face off against powerful foes in the Dragon Ball Legends universe that we haven't seen in the main story yet.
There could be a fanfiction where Shallot gets transported to an alternate Dragon Ball timeline. In this timeline, he has to figure out how to get back while also dealing with the differences in power levels and politics among the characters. For example, he might find that Frieza is an even more dominant force in this new timeline, and he has to use his wits and skills to avoid being detected and killed by Frieza's minions.
Another theme is his relationships. This can include his friendships with other characters from the Dragon Ball Z universe. For example, how he interacts with Goku or Vegeta, and how those relationships develop over time. Some fanfictions also explore possible romantic relationships for Shallot.
One interesting Dragon Ball Shallot fanfiction could be about Shallot's adventures in a new universe. He might encounter unique versions of familiar characters and have to team up with them to face a powerful new threat. For example, he could meet a version of Goku who has different powers due to the different rules in that universe.
You need to be familiar with the Dragon Ball universe as a whole. Incorporate other popular characters like Goku, Vegeta, etc. in a meaningful way. Maybe Shallot has a rivalry with Goku that is different from the ones we've seen before. Also, don't be afraid to add your own unique twists to the power - up systems or the lore of the Dragon Ball world. For instance, you could create a new type of Ki that only Shallot can access.
Shallot can be developed by giving him a backstory. For example, explain where he came from and what his early life was like. This could shape his personality and motives in the fanfiction.
Another interesting concept would be Shallot getting lost in a different dimension within the Dragon Ball Z universe. He would have to find his way back while encountering strange new races and powers, and along the way, he might learn some valuable lessons about himself and his abilities. This could lead to him coming back to his own world as a much stronger and wiser fighter.
Another option is to check out Dragon Ball fan communities on social media platforms like Reddit or Facebook. Members often share links to their favorite fanfictions, and you might be able to find some great Shallot - centered stories there. Just make sure to respect the rules of the community when looking for and sharing fanfiction links.
The Shallot Dragon Ball fanfic is unique because it focuses on a character like Shallot. He's not one of the main characters in the original series, so it gives a fresh perspective. It allows for new storylines that can explore different aspects of the Dragon Ball universe.
