I was on a bit of a scifi bing and well you guys know I love combining SciFi stuff and diapers so I combined em both here. Boys and girls Meet Mark and Ben. Mark is the tall one on the left. He's member of the Martian remake His species was engineered to live on a terraformed Mars. The atmosphere is still a little thin with more CO2 then earth's. So Mark has better lung capacity then normal humans and is a good deal taller and lankier then humans. The nose ridge are purely cosmetic though. Lil things like that are popular minor genetic alterations. They're reversible and aren't on the germline so these superficial augmentations aren't passed down to children. Mark here is an example of the altered humans to colonize the terraformed Venus. Not much different from normal humans. But they have much better eyes that can become wider to see better at night then normal humans but they also see fine in sunlight as Venus has rather long day night cycles. Their skin tends to be darker to deal with extra UV radiation and is actually composed of micro scales which protect against radiation in general.

Mark and Ben here are pretty different from each other but none the less are good friends. They're some of the first colonist of an extra solar planet recently terraformed. It's smaller then earth but larger then Mars. It's between the size of Mars and Venus. It's comfortable for both sub species. Mark and Ben here are seen near the edge of their town happily walking around on the nicely warm planet in only their diapers which for their culture is just another undergarment that is used. So diapers are just as acceptable to wear as boxers or briefs and for many more convenient. Mark is the more open one of the too with the lil rainbow beads in his hair. Mark tends to be the more adventurous of the two while Ben tends to think things out more and is less out going.
