You decided to become a muscular animal-morph, because those were basically the ones you knew that were strong enough to defeat any monster, so you click that. With the body building you will gain, you knew that you would be able to eliminate your opponents easily with the power of any animalistic nature.
You looked closer at the default, blank, player model, and found that the player comes equipped with a thong, a pair of boots, arm braces, a single shoulder-pad, and a sword holster. Basically the clothing of any animal-morph, seeing how that most of the characters who are exactly that would wear less clothing than the human, or elf characters in the game. You then see a bunch of choices for what animal you want your animal-morph character to become, while you play as him.
