The Peloran were genetically engineered to fight. They look human, more or less. Some more. Some less. There’s a bit of a big range in their looks. The ones who came to Earth on Day One of Contact could have all passed for Earthborn humans with very little work. If any. Many didn’t even have pointed ears, and those who did could easily mask them with well-groomed hair. Their skin color and eyes could easily pass for Earth normal with little or no makeup. Better than normal, actually. They were beautiful. Every last one of them could have been a model; no body sculpting needed. Or wanted for that matter. They were better than sculpted. They were born with it.
