Chimeras in the Marvel/DC

First I want to say that I don't really know how to implement Hunter Hunter's chimeras.

So I'm open to recommendations, but I already have some things fixed for this story.

1-There will be a continent that will be equivalent to the dark continent in Marvel.

2- The beginning of the story will be the same as the anime, with the other chimeras as the protagonist preparing for their birth.

3- There will be "nen" but only chimeras will have it.

4- Characters like Nerferupitou will have a greater prominence, especially at the beginning of this work.

I'm open to suggestions
