I don't know if any soup company has tried this before, but Campbell's could create a mascot for an ad campaign for the kids' soup market: Souper Man! He would be a superhero (dressed in the company colors, and with "Campbell's" written across his chest) who makes everything into soup. So whatever kind of food kids really love, he could make it into soup for them, and they would love it. (They could introduce new kinds of soup for kids this way, or a new line of cans of homemade-style casseroles of kids' family favorites like beans & franks, tuna noodle casserole, cheesy hamburger, macaroni & cheese, turkey tetrazzini, etc.) Plus, when kids are sick, or when they're feeling weak from being extremely hungry or exhausted, Souper Man could bring them some Campbell's soup and it would make them all well and strong again; and then Souper Man could tell them about what good food soup is for their health (and yummy!), and for growing up strong, and that it made him strong like he is, etc. And if he doesn't look too much like Superman, I think it would be permissible to do it without even having to worry about licensing Superman (or at least it should be defensible).
Now that I'm thinking about this, it strikes me that Souper Man's powers of making things into soup might work in another way too. Let's say there's a kid eating a chicken dinner, and the kid's parents want him/her to eat his/her vegetables, but the kid won't do it. Well, Souper Man could show up and make the whole dinner (of chicken, rice, vegetables, potatoes, etc.) into soup, and the kid then loves the soup and ends up eating the veggies. So it could end up being a message to parents about how to get their kids to eat a balanced diet, since soup contains so many different food groups in one serving. And this could be a series of ads that makes a whole meal into a soup that then has the kids want to eat the healthy stuff they wouldn't be willing to eat before, with soups like Chunky chicken rice with vegetables, split pea with ham (which also has carrots and potatoes), bean and ham, chicken mushroom chowder, chicken corn chowder, etc. And this shows Souper Man's powers to also include the ability to get kids to eat their vegetables willingly, which is a super power indeed!
