It could be a group of travelers in the car. They look up at the star and start to have different ideas about it. One might see it as a sign of hope, another as a threat. The star could then start to have an impact on their journey, like causing strange phenomena. So the main characters are these diverse travelers, each with their own relationship to the star while they are all in the car together.
The main character could be a lonely driver in the car, and the star could be a sentient being, like a star spirit. They could interact in some magical ways.
Maybe the car is on a journey at night and the star in the sky seems to be guiding it. So the story could be about a lost car finding its way with the help of the star.
Obviously, Star could be one of the main characters. She could have an adventure in the mermaid world and her character traits like her fearlessness and her ability to adapt would make for an interesting story. Another main character could be a mermaid named Marina. She could be the one who helps Star understand the mermaid world and they form a strong friendship.
Well, obviously the moon and star themselves could be the main characters. They could be personified entities with their own personalities. The moon could be calm and wise, while the star could be more impulsive and energetic.
Well, obviously Tom and Star are the main ones. Tom with his demon powers and complex personality, and Star with her magical princess powers and her free - spirited nature. They are the core of any Tom Star fanfiction.
Star and Marco are the central figures. Star, with her unique personality and perhaps some magic involved, and Marco, who is more down - to - earth. Together, they form an interesting duo for this car - washing scenario in the fanfiction.
The main characters could be two lovers who are from different social classes. Their relationship is a taboo in their society, and they use the secrecy of a car ride to be together for a short time.
I think MegaMan would be one of the main characters for sure.
The main characters in the love story are Star and Marco.
The main character could be an old - fashioned railroad engineer. He has spent his whole life working on the railroad and now has to deal with new machines that are threatening his way of life.
A possible main character could be a rose plant. Roses are often associated with love, so it would be interesting if a rose plant was in a love story with a zombie. Maybe a football zombie, who is strong and tough on the outside but softens when he meets the rose.
