Tim and Lexi
My current work in progress features two protagonists, Tim and Lexi. I wanted both a male and female character not because the female character needs the male, but because I wanted to show equality.
I wanted to create realistic and fun characters that are cheeky, brave and impulsive. I don't go into a lot of detail about what they look like because to me, that's not important. I want the children reading my book to imagine themselves and their friends in the roles of Tim and Lexi.
Whether or not this will remain true after I've edited the second draft, I don't know.
This is what I have so far.
Lexi

Alexia comes from a single parent home. She has a brother and a sister who live with her dad and his new girlfriend, and she has her mum. She recently moved with her mum to the town in which Tim lives and have moved in on the same street as Tim.
She's loud, outgoing and plucky. She loves adventure but there's something quiet about Lexi. While she is loud, she has a quiet thoughtful side. She has a thinking side of her which processes what's happening and makes her ask questions that are important but are also unexpected.
Lexi is an experience collector. She likes to do things and find out what happens later. However, she's not completely careless and knows when she needs to use caution. She has her own boundaries and is very happy with them. She is smart and while her impulsiveness doesn't always allow her to show how smart she is, she has a depth of maturity that is very heartwarming.
Tim
Timothy is the youngest of two boys. His older brother David is a teen
and the possessor of all the best computer games, which Tim covets. It's not until he meets Lexi that he's brave enough to pinch one of his brother's games to play with her.
Tim is used to being one of the cleverest people in the room. At school, he's learnt that the teachers know he's clever and he acts accordingly. He's reserved, thoughtful and proud. Yet, there is a vulnerable side to him. He knows he's not as clever as people make out and he's not as 'spur of the moment' as he would like to be. He envies Lexi's ability to just give things ago and see what happens.
Tim is not an experience collector. He picks and chooses what he wants to do and if he feels a bit out of his comfort zone, he may withdraw. The one thing that makes Tim shine is where something is out of his comfort zone, particularly in the climax of Book 1 where Tim can put aside his worries and reservations.
Tim is kind, loyal and friendly. He welcomes Lexi as a friend on their first meeting and while he doesn't agree with everything she says or does, he accepts her immediately as someone he can trust and be friends with.
How I Feel
I really like these characters. When I'm writing about them, and I know
other writers have said this as well, I almost picture my own children. They are very loosely based on my own children although my own are much younger than the characters here and haven't quite settled on their own personalities yet.
What I Wanted to Achieve
I want to show that while they are different genders, there's an equality between them. Lexi and Tim both have strengths and weaknesses and they support each other. I want to say that it doesn't matter that one is a boy and the other is a girl, they are both people who can achieve anything they want to.
