Anthros, or Animal-Morphs were basically the most powerful to fight against, because they were stronger than humans, and could kick any other monsters butt once they got their hands on them. Of course, you didn't have a problem with playing as animal creatures in video games, because some of them were actually science fiction related.
However, before you could select which kind of Animal-Morph you wanted to become, you decided to select your body proportion to see what kind of body you will be showing to both the ladies that stare at you, and the monsters you will be defeating. There were basically only 3 for you to choose so far, which were muscular, feminine, and overweight. Overweight makes you completely fat, feminine makes you have a huge butt, and thin hips like a woman, and muscular gives you 100 muscles on your body.
