As far as I know, there isn't a widely known fanfic solely focused on Beerus and Champa's father. However, the Dragon Ball fan community is vast and creative. Some fans might be interested in exploring the backstory of their father, but it's not a common theme that pops up regularly. You could try checking out some of the bigger fanfic platforms and search for related keywords to see if there are any hidden gems.
One interesting Dragon Ball Champa fanfiction could be about his backstory before coming to the Tournament of Power. It might explore his relationship with Beerus in more depth and how they became rivals.
A powerful, ancient being from a forgotten universe could be the main antagonist. This being could be jealous of Beerus and Champa's power and status, and decides to challenge them to take over their universes.
One idea could be a cooking competition between Beerus and Champa. They could each bring their own unique ingredients from their universes and compete to make the most delicious dish. It would be a fun way to show their rivalry in a different light.
I've heard 'Champa and the Lost Realm' is great. In this fanfiction, Champa stumbles upon a long - lost realm full of powerful warriors. He has to battle his way through them to get back home, and along the way, he discovers some secrets about his own power and origin. It has a lot of action and mystery.
The 'saat bhai champa' story is not something I have in my knowledge base. It would be great if you could give some more details about it, like which region or culture it is from, so that I could try to find out more about it.
It could include the origin story of their father. Maybe how he came to be a powerful being in the Dragon Ball universe. It might also explore his relationships with other deities.
Well, in many Champa x Male Reader fanfictions, a common theme is power dynamics. Given that Champa is a powerful character in the Dragon Ball series, there can be a play on the power difference between him and the male reader. Some stories also revolve around the theme of discovery, where the male reader discovers new aspects of Champa's personality or the Dragon Ball world. And of course, the theme of love and attraction is quite prevalent, with the two characters gradually falling for each other.
You can try fanfiction platforms like Archive of Our Own (AO3). There are often a variety of fanfictions about different pairings, including Champa x Male Reader. Another option could be FanFiction.net, but the quality may vary more. You can also check out Tumblr, where some fans might share their own written works or links to relevant fanfictions.
