@LukeAlmighty @matana apparently this dude was only a background artist for the game and the series co-creator Yoshio Sakamoto said that this being true was as likely as Metroid Prime getting a PS2 port.

One of the only things we know about Hirofumi Mastuoka is this quote, which was an answer to "a secret about Samus only you know." So he was either joking/trolling or he's retarded. There's also the potential that the word "newhalf" can refer to a more masculine female but I don't know Japanese well enough to confirm that and I suspect only Japanese people who were at least in their 20s in the late 1980s would know.

Anyone that actually believes this has more brain rot than people who think Kirby is non-binary.
