Well, Bill Cipher would obviously be one of the main characters since it's about his rebirth. There might also be the characters who were associated with him in the original story, like Dipper and Mabel. They could be trying to stop him or figure out what his new plans are.
The main character is surely Bill Cipher in 'bill cipher reborn fanfic'. But we could also expect to see other important characters from the same universe. For example, Ford Pines might be involved. He has knowledge about the strange and supernatural, so he could play a crucial role in dealing with the reborn Bill Cipher. And perhaps some of the local townsfolk who end up getting caught in the middle of whatever chaos Bill brings.
In this 'bill cipher reborn fanfic', Bill Cipher is the central figure. However, depending on the plot, characters like Soos could also be important. He has his own charm and way of dealing with things, and his loyalty to the Pines family might make him a key player in opposing Bill. Also, Wendy might be there. She's brave and not one to back down easily, so she could be involved in any confrontations or attempts to understand what's going on with the reborn Bill Cipher.
