Superheroes are licensed. Any free or cheap ones will be illegal. The website who might sell them needs to furnish proof of having bought the license.
Digitising your own, even from your own drawing, or the net, is also illegal.
As is sharing designs. So, if you are going to send her designs of Superheroes, DON'T. And if you are going to give her a link to Superhero designs, also DON'T, unless the website is legit with proof of having purchased the license.
