What can I use for homemade Ben10 Alien Force Board Game square ideas?

My son will soon be 10. He is having a Ben10 Alien Force themed party. I am making a huge game where the kids will be the pieces. I have a big cardboard box that will be the die, that the kids will throw. Unfortunately, I am having trouble coming up with ideas for the squares. I have the obligatory, go back two spaces, advance one space, and lose a turn. Please help, it will be greatly appreciated.
