Well, I'm no expert at RPG Maker (...yet!!) and especially not 2003 or anything else (except XP, that is) so I'm not sure... But couldn't it be that when you added the sprite of Vegeta, you didn't use the green color as transparent. If it's not set to transparent, it will be shown. Just as in your example.
Try this, if it works then... CONGRATS!! xP However, If it
did work, please add [RESOLVED] to the topic title!
The other question I've got NO idea on... sorry ^^'
