Although their elegant movements are of little use in battle, except when dodging attacks, Lopunny's rhythm and agility have made them beloved across Sinnoh as dancers capable of charming humans and pokemon alike. But while pokemon flock to them as potential lovers, this dancing ability has come at a cost, in not only creating a bipedal body shape, but a unique one which has made it extremely difficult to lay eggs in the traditional manner. The large ears of Buneary have difficulty developing in an eggshell, and Lopunny's narrow pelvis, being angled for bipedalism, has made egg-laying in the wild a dangerous process,
Lopunny are of interest to science for they have solved this issue in a way only paralleled in the pokemon world by humans and loosely by Kangaskhan; they are able to gestate mostly, in some cases entirely, within the mothers' body. For some time, because of the similarities of their reproductive systems, these pokemon were thought to be ancestral to man, and this idea captured the imagination of Sinnoh.
Humans have celebrated this supposed dancing heritage and chosen to emulate the techniques of the Lopunny incorporating them into video games and pokemon contests and celebrations alike. Humans, however, have only a vague shape in common with Lopunny in appearance; the puffy hands and tail and especially the enormous ears these pokemon possess have no counterparts in humanity, although they are often worn in costume. Man is a primate, an order named for Primeapes, their close relatives. Although some would still prefer a relation to such an elegant creature, Lopunny mania is nothing more than the quaint custom of our early scientific past which is still adhered to only by a few psuedo-scientists in Sinnoh.
