Big fan of exploring robot characters' takes on gender (and associated things e.g. gendered pronouns 'cause my language doesn't have those) so asked about it:

Omega, while masculine coded, wouldn't care what others refer to him as because gender is not a relevant part of his identity: Being the "Ultimate (E-series) Robot" is what's important. Probably thrives off of being considered dangerous & identifies himself as a threat. (I do love different takes on this such as @generic-sonic-fan 's hc where Omega, in contrast, identifies with masculinity *very* strongly.) Anyways here's related art.

"Metal Sonic wants to be the one true Sonic. The real Sonic is already a 'he', so Metal has to be 'he'."

"Has to be," is an interesting statement. I'd like elaboration on (Metal's) reasoning for this: Is copying Sonic's traits "innate"/"natural" for Metal in a way where it's genuinely how he wishes to id, or is it a case of: All Metal knows is to copy Sonic, so he lacks an original identity? (Or that there is actual individuality under all that code and blue paint job, but Metal doesn't know how to/can't express it, or maybe doesn't want to acknowledge it at all?) Just thinking out loud here.
