My game will be called the invincible man, about a guy with endless invincibly. But I can't think of anything for the designs Can anybody help me with them?

Take a bit of each Marvel comic you like. I'm sure the people who created Superman, Batman, Hulk, etc… put a lot of themselves in their characters, the reason why they had so much success, so, wonder yourself, what are the more amazing power, what are those you dream to have if you were invincible. See how your character can counter-attack each kind of attack to become invincible.
But i don't see, if your character is invincible, how the game is challenging?
