I am already in the planning stage for the fourth volume of my main series, I have decided to introduce a weakness that the Young Guardians, and neohumans in general, all share. Now every neohuman has their own unique weakness based on what powers or physical conditioning they possess, but in volume four, there will be a weakness that they would all be vulnerable to as a species. This way, the Young Guardians and their allies would be able to face a enemy that could potentially kill them, which will increase suspense and tension. With this in mind, the possibility exists that one or more of the main characters could die in volume four, which would provide a much darker and emotional ending. Just thinking about this weakness gives me the chills because what I have in mind is both repulsive and unexpected.
