What content should I post to tease a superhero book series I'm working on?

I had an idea a while ago that I should make a superhero movie series, but being a kid means I don't have those resources so I just sit on a word document and wrote them as books. It was a passion project at first but I'd actually like them to go public and see what people think.

That said, I think Tiktok is the solution. But how am I supposed to go about this? Should I do memes and skits? Or just talk about them? How should I approach this?
