Smart Four Two I Am Writing A Pokemon Story And I Have Four Main Character's Two Girls And Two Boys Any Ideas For Names?

I am writing a pokemon Story and I have four main character's two girls and two boys any ideas for names? - smart four two

One Girl: red-blond hair. Increasing and is ready.
Girl two: it tends to be concentrated. Do not listen to anyone. Black with red hair. More tax smart.

A boy, dark brown hair. Converse black jacket with dark blue. Tends to be too arrogant.
Boy Two blond hair. Respect and help, never talks back. Goody Two Shoes.

PS I would like to name really good, I am open to all ideas.
