Exploring the idea that female and male Predator/yautja have little sexual dimorphism, as sourced from various media (written and visual). I like the concept that females only really develop breasts when they are nursing, and once the infant weans her body resorts back to a more flat-chest state.
There are canon female predators with breasts, such as Sister Midnight, the female Predator option in the game “Hunting Grounds”, and some sparse mentions throughout the books, but I take much greater inspiration in Big Momma. I remember, long ago, getting a copy of this comic and not realizing the Predator was a female until it was mentioned and even then I had to reread it several times to ensure it wasn’t a typo or mis-translation (this was back in Spain, so the copy was in spanish). The book “Avp: Prey” also mentions female yautja as not that different from males aside from greater size and strength.
That’s not to say that females with breasts are wrong. We only have to look at ourselves, humans, to see the vast variety of different body types. No gender fits in a perfect physical descriptor that encompasses everyone. It’s very likely that Yautja Prime has similar diversity. Females may be larger and flat-chested for the most part, but some can be leaner and smaller, some can develop permanent breast tissue, or softer features, etc. On its opposite spectrum there could be females that are near indistinguishable from their male counterparts aside from their reproductive organs.
Breasts are not the definite characterization of femininity and needs to be normalized more.
