yeah this, and we make characters that aren't cannon either
at this point in mocing we seem to have modified what we define most species in the MU with some of our own human traits such as body differences in gender while cannologically its only a mental difference, we've also done things like remove the elemental connection to gender for the most part.
To me we've kinda morphed some things in cannon into what we think is better, try to find someone who will only MOC matoran and have their gender the cannological elements, it kinda sucks that only like 3 out of 14 of the naturally occurring elements are female, it limits creativity so we got rid of it.
yes okay but then all the male toa aside from him have broad shoulders and gali 2016 has small shoulders too, and her 2015 form looks like she has smaller shoulders and also like she has wider hips.
But I think its fun to build mocs that have a more complicated feminine shape rather than the simple male shape.
