The violence depicted in the film mainly takes the form of the human fighters attacking the monster with artillery and bombs while the creature retaliates with radioactive light beams.
Destroyed buildings and infrastructures are depicted with very little portrayal of infliction of pain and injuries caused by human beings.
The monster at the beginning releases this red colored fluid from its gills. It can be mistaken for blood.
The monster also bleeds due to a strong attack from the military in an attempt to exterminate the creature.
Death is implied for many of the cases.
