My novel's world has ugly little monsters infesting the planet to the point where all the "regular" animals are kept in secure compounds for protection. I was typing up the part of my novel where I began explaining a little bit about what was going on when I thought to Pokemon...and basically any fantasy story involving monsters. All the different types of monsters are named. Problem is, the point of my novel's monsters is that they are abominations, and are not really always 100% alike looking. The spider types of monsters will have differing numbers of eyes and legs. The tentacle mass monsters might only have two fat tentacles or 100 skinny little tentacles. The appearance is sort of random only there are some similarities. Would you consider it boring or lazy of the author not to name each different type of monster?
