Another thing, am I the only one who finds it weird that the level 5 is the ultimate form? By default, every monster should want its spawns to also become monsters, so the monster form should theoretically be the apex of a superhuman. Evolving up to level 4 makes sense, but evolving to level 5 without turning into a monster should be nearly impossible, as it’s the last chance for a superhuman to become a monster and potentially the strongest one possible.
A level 5 should still be overpowered, but turning into a monster during the evolution to level 5 feels like it should be the "perfect form."
I started reflecting on the strongest monsters we know, and no matter how powerful or intelligent they may be, the fact that they are monsters and not superhumans means that they all turn out to be failures, and it's feels wrong in some way.
