Now I think about it, did you notice than half-human hybrids tend to become significantly stronger than pure-blooded monsters ? It's like human nature is a catalyst to unlock the potential of its other half. Sounds like John's central theme permeates fantastic fiction in general, and that he's special in turning this catalyst effect onto itself to directly unlock human nature's own potential, triggering an exponential chain-reaction of expansion/evolution that explains his overwhelming growth and abilities compared to supernatural species.

Seems like a cool, legit and immersive way to explain/justify his limitless potential, while cementing his "beacon of hope" side by clarifying how this potential for transcendence is inherent to all human beings. Maybe it should be mentioned somewhere in his background ? Would probably be a useful contribution.
