saying that these robots are gay/lesbian/bisexual/asexual makes more sense to me than saying they are transgender, because as inorganic beings they do not have hormones, and are manufactured the way they were meant to be from the beginning.
robot sentience is of course a thing in the megaman universe, and a robot could probably have their body altered to match their gender identity. but... i don't think including "pre-estrogen" and "pre-testosterone" in your headcanons makes a lot of sense here.
that said, you're 14.
