Whats a good creative story..?

Im doing a project in my art cl and I cant come up with a creative, imaginative storyline for my character I drew his name is boxman(I know stupid right..?). I want to see if anyone could please give me some advice on what would be good for it. You can make it as imaginary as possible, like where he lives and what galaxy he comes from, etc. I really need help with this because Iam very uncreative. thank you! Who ever has a legit answer will be chose for best answer:)
