Trixie could also be a main character in these fanfictions. She might play a role like being Speed Racer's supporter or even getting involved in the races herself in some lemon - related situations. For example, she could be the one to discover a secret about the lemon - powered engines.
Obviously Naruto himself. Since it's about his godlike speed, he's the central figure. Sasuke is also likely to be involved as his rival. Their interactions, with Naruto's speed being a major factor, can create intense and exciting storylines.
Obviously, Harry Potter himself is usually one of the main characters. He is often the one who has to face the basilisk in these fanfictions.
In some fanfictions, Darkseid might be paired with the Black Racer. Darkseid's thirst for power and the Black Racer's role as a bringer of death could create a really intense and dark story. Also, characters like Raven could be paired with the Black Racer. Raven's connection to the supernatural and the Black Racer's otherworldly nature could lead to some really unique storylines.
Flash is often paired with the Black Racer in fanfiction. Their relationship is interesting as both are connected to the speed force in different ways. Flash's positive, heroic nature contrasts with the more mysterious and somewhat darker Black Racer.
One interesting story could be about Speed Racer's encounter with a mysterious racer in a lemon - themed race. Maybe this new racer has a super - fast lemon - shaped car with unique abilities that Speed Racer has to figure out how to compete against.
Alina is also frequently involved. Her connection to the Darkling in the original work makes her a natural addition in many fanfictions. Their complex relationship can be further explored or even rewritten in different ways in fanfiction.
Y is another popular one. She is the only female racer in her team and she breaks a lot of gender barriers in the racing world of the fanfiction. Her intelligence and ability to outwit her opponents, especially in tricky track situations, make her a favorite among readers.
Obviously Naruto himself is a main character. He is the one with the pacemaker so he is central to the story. Sasuke might also be involved. He could be initially skeptical of Naruto's new situation with the pacemaker but then come around to help. Sakura too, as a medical ninja, she could play a crucial role in understanding and perhaps even trying to modify the pacemaker.
There can be original characters created specifically for the fanfiction. For instance, a detective who is obsessed with bringing down the Joker but slowly starts to lose his own sanity in the process. This character can provide a new perspective on the Joker's reign of terror.
Well, obviously Gaster is the central character as it's about his pregnancy. But often, other characters from the same fictional world might be involved. For instance, characters who are friends or colleagues of Gaster could be there to support or oppose the situation. It might also include characters who have some sort of special connection to Gaster's unborn child, like a potential mentor or an enemy who wants to harm the baby.
