One of the hardest parts for me in writing is figuring out what I need to know about my characters. Here are some templates for what you need to know about your characters. 

Here is the template that I use for creating characters in my stories:

Name: 

Nicknames:

Gender:

Age: (actual age and birthday)

Orientation:

Physical Description:

Personality: (positive and negative traits here. dont want a perfect character)

Extra Information: (this would be extras like hogwarts house, clothing choices, pets, relationships with other characters, occupation, etc.)
