Well I've come up with yet another alien species. Boys and girls meet Auros of the species Spacialar. His kind evolved in a rather odd habitat. A small astroid field which had just enough gravity to hold enough of an atmosphere to have some liquid water. The Spacialar are a very hardy species able to withstand extreme temperature variation. They can survive in even the vaccum of space. They don't have a respiratory system as the atmosphere there was at a premium and hopping to astroids outside the atmospheric area was common. As such they don't breath. Even the sun's radiation doesn't harm them at all. In fact they use it to there benefit. The partial green color of there skin is due to a type of chlorophyll in there bodies. They do eat but can survive without doing so for a very long time. As for locomotion they jump from asteroid to asteroid but can also use a form of telekinesis for powered flight. Another fun fact is that they have no native spoken language as they primarily live in the near vaccum of space. Their primary means of communication is telepathy.

Auros here is seen on one of their astroides looking around and having fun. In the distance we can see a fairly green habitable world that the Spacialar have trade agreements with. Auros here wants to see that world up close someday. He may very well do that. His species are long lived. As for the diaper. Well in low grav if your not wearing one and take a leak you get pushed off in the other direction.
