I do not know where you can get this because I didnt even know they existed, Im also assuming you found it already looking at the topic date. But wow! I must say that you really thought this through; children love comic book, and they would definitely love Bitcoin (not just learn about it) if its in a comic book. In fact, if Bitcoin is attributed to some kind of superhero, they may even go as far as asking you to get them some Bitcoin. This is a fantastic idea which will definitely work.
comic book or even videos that will show it as cartoons and use bitcoin as superhero lol .
we even are not kid consider bitcoin as our superhero

so I will also love teaching my kids about How good Bitcoin for them and their future of course.
OP it is good that you share this here.
If Bitcoin is shown as a superhero, then he must have superpowers and there must be a villain in the plot. If we fantasize, then when powers should Bitcoin have? Ability to make anonymous payments? Not the best thing to teach kids from very childhood. And a villain? Banks, government and SEC? Also not a best example who to show as a bad guys.
Imo, comic books and cartoons are great for education, but as to teaching Bitcoin it doubtfully would reach a large audience, as there are more interesting and popular comic books and cartoons that kids will be interested in.
Those who write movies dont just sit down and write, they have to think on the whole story and make sure that everything connects perfectly. Those who write comic books are no different. You cant just create a comic book without having an enticing story line. So, it depends on the author and how they choose to write the story. If they call the bank the villain, hows that bad? And if they dont want to, they can make them both superheroes with Bitcoin being the more powerful superhero. Its all based on idea.
