The Peloran that made Contact with us get cut and bleed just as easily as most humans. They just heal really quick. But most Peloran have thicker skin than that. Literally. Well…maybe denser is the better word. Definitely stronger. Firmer as well. Peloran skin actually acts as a kind of low-grade armor, you see. It’ll shrug off the kind of things that normal humans live in fear of. Low-caliber bullets. Paper cuts. Legos. That’s one of the reasons so many of them look just a little bit different than us. They were designed for war, and didn’t disappoint one bit by the time they were ready to field. I still remember the day I first saw a battalion of them march unto the landing field at Sunnydale. God that was an amazing sight.
