Here's a little character sheet to be more specific? 

Name: (Doesn't matter, as I'd come up with them myself) 

Age: (I'd prefer teenagers, as the story bases around them. But parents or siblings would be a nice add on, especially for bacsktory) 

Gender: (Any gender, tbh. Male, female, trans, etc. Makes them interested, and may add to the story and conflict idk??) 

Sexual orientation:(Same explanation for gender) 

Personality: (A short list of quirks, hobbies, traits. Things that make them unique, and likable. Maybe any sports they play, or clubs they do, cliques they hang out with and how they are to others) 

Backstory: (Nothing too in depth, just a small paragraph to explain why they're at the school, any struggles they have had. Any future struggles that may come up? I will be writing their stories so anything will help.) 

Appearance isn't important, as I'd make them the way I'd see fit, but if you really love this character and imagine something specific for them, go ahead and state it. 

If I use your character, I will definitely give credit. I'd list your username on here, or your tumblr, as that's where this will be going. 

This does not have to be perfect, it's just brainstorming to help me come up with characters.
