Ok here a few reson y people draw reamon with boobs
(1) the voice actors in the Anime r woman
(2) the shape of renamon's body is in a ora glass which in most cast resmable that of the human female form.
(3) now even thow digimon not have gender most fan want to belive that they do cause of these few digimon Angewomon, lilymon, and ladydevimon. which r all female, were in the first seson and only two of them have a male contuner part.
well renamon is a female but with out boobs and i remeber seeing an episode of renamons laugh in janesse then in english. idk y but i was on Youtube one giorno looking up random video and i seen this one about renamons laugh which te could tell that renamon is a she not a it
i have to agree with dargox many people while they dont relize base a lot of observation on poplular o steriotypical thought and the way renamon was created plays on many of those thoughts and what many dont understand is te cant judge creatures on the same factors as te do humans
