As powerful superhumans can be, they still possess a degree of mortality. Like their bodies and minds, their powers could degrade or become unstable as they get older. At the end of my fourth and final volume of the Young Guardians Series I intend to explore this concept. Even though the Young Guardians will retain the appearance of teenagers, there will still be a part of them that ages after they live a few thousand years. When that happens, they will be past their prime and their powers will be boiling over. This will be a good end to their story and the beginning of their legacy, which will lead into the sequel series.
