How do i make a character selection menu (2d game) ?

I recently made a 2d game. With an idea to make the game more interesting i thought of character selection. I had the player(object) as the name gamePlayer1 and the image i want to replace the sprite image of gamePlayer1 is "charlie". The major problem i was facing is that both the things are in different scenes. The character selection menu(Scene 1) and the Game(Scene 2) I will be doing it using a button (using the onClick() function) Please help me This is my first video game and i am very exited for it to be completed Thank You
