it can come with health complications but can also just be the lack of pigment

*cough*

not biologically, anyway

after all, both dimensions have "Mobians" who don't look any different from each other so I don't see why aliens would be any different

they could have some cultural differences but not much beyond that, just different history and a different leader

but I'm very close to switching up to "Black Arms used to have females but they were wiped out in whatever apocalyptic scenario ended in only Black Doom's colony surviving and asexual reproduction of males is all that remains"

there is the "why don't they just make more females with their biotech" question but that can be explained with either "Black Doom saw no need to" or "they can't because they lost that genetic information"

mammal sex chromosomes are XY and XX, so cloning tech could take the XY and remove the Y then duplicate the X to get XX

but other species groups like reptiles and birds have ZZ and ZW, so only having ZZ individuals to clone from means only making more ZZ

There is zero justification for a Sonic fan to hate and harass anyone over politics or any other beliefs. Sonic hates bullies and that's what that is: bullying.
