Here are some allied forces, the humans and the Nephilim in different suits and types and all that
First is an android controlled by humans using a special computer.
Next are the Nephilim. The top, is a regular, unarmored Nephilim
Now, is a Nephilim in a wetsuit. Notice the fins on the shoulders
(Sorry for the blurry pics) And now, in bulletproof armor in the Nephilim with a grenade launcher and a bazooka. He is ready for battle!
UPDATE: IF YOU LOOK UP NEPHILIM, HYDRA, AND/OR RAKSHASA, YOU WILL ACTUALLY GET RESULTS. THE RAKSHASA IS A DEMON FROM ANCIENT CHINESE MYTHOLOGY, THE HYDRA IS A MONSTER FROM GREEK MYTHOLOGY, AND THE NEPHILIM IS A CREATURE THAT IS HALF HUMAN, HALF ANGEL THAT IS FROM THE BIBLE
