Comic Books that have this concept feature normal animals found on earth that attack humans, robots, aliens, etc. have the following traits.
- The animals have not been genetically engineered by man, robots, aliens, etc. so a 100ft long great white shark that has telepathic powers would not belong to this concept.
- The animals are not robots that look like and/or act like animals.
- The animals are not gigantic beyond what is currently possible by evolution. So something like King Kong doesn't fit the animal attacks concept.
- The animals are not mystical beings or shape shifters. So a spirit wolf or someone who shape shifts into a bear and kills someone doesn't fall under the animal attacks concept.
