So if you haven't been made aware there has been a recent improvement and genetic engineering. Super beings are being created and have been made that exceed logical explanation. They're kept under wraps of course, but these "monsters" that are neither human nor animal have an average life expectancy of 60-200 years. Some are cybernetic and have no soul but are part biological. Their functions are mandated by computer orders.
Many are malicious predators, like werewolves and tigermen. They have the intelligence of a human being, the lifespan of a human being, but the body capabilities of a beast. Their mandates are to live in the wild, and if you ever seen one you would either be eaten, or no one would believe you. Basically.
They're like angels and demons, and of course there is miraculous improvements in non-beast genetics but how much can you improve on the human form, and intelligence? They're like super soldiers except I do not know if they were made by the military or not.
They bump and crawl in the night, and maybe they were not genetically made and have been here/mating this entire time. I don't know. I suspect that they can be animagous as in, they can evolve/molt/change form periodically. It would allow them to live longer and change/evolve if necessary if their previous form proved not very adaptable to their environment. It does take much energy, pain and suffering to do so, with the possibility of infections and so on, but I think their immune systems are not the same as ours.
Miracles maybe do exist, maybe these beasts are angels and demons, maybe the demons are angels, do you ever see predators in the wild that are hunting? Not rarely, and if you do they're stalking you. Imagine that matched with human intelligence. Obviously some have no trace of humanity left in them, but don't think that they are stupid, or have lost intelligence. They're merely more predatorial. I think that they may be released by owners/controllers, the non human kind to awe/inspire/hunt the general masses at various times.
There are of course "goats". Things with horns, that may have tremendous energy and are maybe completely herbivorious, but I believe that they could probably eat meat.
It brings to question the limitations of psychonetic telepathy mind control and the capacity of 'double-souls' where one soul can inhabit more than one body without knowing it for survival, almost like voldemort splitting his souls, but more natural and not evil. This last part is more of a guess/hypothesis for beings to almost be cloned/be able to replace the brain stems memory banks, sort of like evolving.
and of course, dragons. They are not stupid, oh no, but they do not have any trace of humanity in them. Cuz they're so big. Roar. They like cow meat i bet. Delicious yummy cows.
What is the limitation to animal/human evolutionary capacities. What more could there possibly be?
