It's possible that the main character is a mischievous kid who is always getting into trouble, and the wedgie is just one of the many things that happen to him. There could be other kids in his neighborhood or at school who are secondary characters. They might be the ones who witness the wedgie incidents and react in different ways, some laughing, some feeling sorry for him, which all contribute to the development of the story.
I don't know the exact wedgie game story you're referring to, so it's hard to say. But it could be a group of school kids like Tommy, Sarah, and Jack.
Once there was a little boy named Tim at school. A bully named Jack decided to give him a wedgie during recess. Jack grabbed the back of Tim's underwear and pulled it up hard. Tim was really embarrassed and started to cry. But then a teacher saw what was happening and scolded Jack. After that, the other kids learned that wedgie - giving was not a nice thing to do.
I'm not sure specifically which 'wedgie kid story' you mean. It could be about a kid who experiences getting a wedgie, like maybe a story of a bullied kid at school where the bullies give him wedgies and how he deals with it.
There are two central characters in the 'the kid and the lion kid story'. One is simply a kid, who could be a human child or perhaps a young goat (as 'kid' can have different meanings). The other is the lion kid, which is a young lion. Their relationship and the events that occur between them form the core of the story.
The girl herself is the central character. However, depending on the nature of the story, there could be other significant characters. If it's a story about revenge or getting back at someone who gave her a wedgie, there could be a character who helps her plan her revenge. Or if it's a story about growing up and learning from an embarrassing experience, her parents could be important characters as they might give her advice on how to handle such situations at school.
As I don't know the details of the 'Atomic Girl Wedgie Story', the main character seems to be this 'Atomic Girl' from the title, but there could be others involved depending on the nature of the story.
If it follows the main 'Family Guy' cast, it would likely include Peter Griffin, the bumbling but lovable father. He could be either the giver or receiver of the wedgie in the story. Also, Stewie, the evil - genius baby, might be involved as he often gets into all sorts of mischief. And Lois, Peter's wife, could be there to react to the whole wedgie situation in her own exasperated way.
Given the lack of information about 'Star Fox Wedgie Story', it's almost impossible to accurately name the main characters. It might be a story that takes the Star Fox characters and puts them in a completely wacky and unexpected situation where the idea of 'wedgies' somehow plays a role, but without further details, we can't be certain about who the main characters are.
Based on the title, Star Butterfly is likely to be one of the main characters. There may also be other characters who are either friends or foes of Star Butterfly. For example, there could be a bully if the wedgie is given maliciously, or a friend who helps her out of the wedgie situation.
Since I don't know the exact story, it could be the usual Jungle Book main characters like Mowgli, Baloo, and Bagheera. Maybe Mowgli is the one who experiences the wedgie situation, or perhaps one of his animal friends causes it to happen.
