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.
The different interpretations of the characters are great. In some fanfictions, Goku Black might be portrayed as even more evil or cunning than in the original series, and Hit could be shown with new strategies. For instance, a fanfiction might have Hit teaming up with other characters from different universes to take on Goku Black, which adds a whole new dimension to the story.
Plants vs. Zombie Heroes was a game where the " guaranteed hit " usually referred to a certain attack method or skill that had a high hit rate and could accurately hit the target.
In Plants vs. Zombies, some plants had certain skills such as the Sunlight Mushroom's explosion and the Frost Archer's freezing skill. These plants '''sure hit' skill allowed them to easily cause huge damage to enemies and become powerful plants in the game.
In the game, players needed to choose different plants to combine different tactics in order to effectively fight against the enemy. Therefore, the existence of the " Must Hit " skill also made players pay more attention to the accuracy of their attacks when choosing plants in order to better utilize the advantages of plants.
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.
There's also a fanfiction called 'Hit's Vengeance on Goku Black'. In this one, Hit is on a mission to avenge the destruction Goku Black has caused in the multiverse. It has some really intense fight scenes that are well - written. The author does a great job of portraying Hit's calculating nature and Goku Black's menacing presence.
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.
