Well, in the MHA manga, Dabi does meet his end. It's a poignant moment that has significant implications for the story's progression and the dynamics among the characters.
One popular theme is Dabi's backstory exploration. Many fanfics delve into his past, his relationship with his family before he became the villain he is now. Another theme could be Dabi in different AU (alternate universes), like a modern high - school AU where he's a troubled student. And there are also fanfics that focus on his relationships with other characters in the My Hero Academia universe, such as his interactions with Hawks or Shigaraki.
Hawks is a great character to pair with Dabi in fanfic. Their relationship in the original story is complex and full of tension, which can be explored further in fan - made stories. There's also Shigaraki. Since they are both important members of the League of Villains, there's a lot of potential for interesting dynamics between them in fanfics.
