The characters must look like humans. If a character looks like a human, it should be treated as a human even if it is unrealistic. Characters that are clad in armor or obscured in some other way, but understood to be human, should also be considered human. Implied violence against humans, such as the shooting of vehicles understood to have humans inside, would also be considered violence against humans.
