A ssbu fanfic could focus on the backstories of the existing characters. For example, exploring the origin of how Mario and Luigi first discovered their powers and how it relates to their fighting styles in the game. This would add depth to their characters in the fanfic world.
One idea could be a story about a new character entering the Smash Bros. Ultimate (SSBU) universe and having to learn the ropes of the battles. They could start as a novice and gradually become a strong fighter.
Some SSBU fanfictions explore the relationships between the characters in more depth. They might show how characters from different game universes interact and form friendships or rivalries, which is really fascinating to read.
First, choose your favorite SSBU character or a group of characters. Then, think of a simple plot like a small adventure or a friendly competition among them.

One idea could be exploring the characters' backstories more in - depth. For example, delving into Marvin's childhood and how it shaped his adult behavior.
