Something I noticed about Mega Man X Dive. The White Day costumes are some sort of tradition in Japan where recipients of Valentine's Day gifts are expected to return them to the giver.
Axl has a White Day costume. X doesn't.
Granted, X doesn't get any special costumes outside of collabs, but let that sink in. Axl is considered more romantically desirable than X.
This actually says a lot about how developers feel about X as a character. They literally tried to replace him with Axl in the past with X7, which would allow him to "pair better" with Zero. Interviews regarding Command Mission's development suggested that the developers found X boring and assumed that the players would get tired of him, so they decided to alter X's personality and design to make him more appealing.... by taking away the element of his personality that made him stand out from the world around him, entirely missing the point of his character. In short, Japanese developers see X as disdainful at best, and mentally weak at worst. It intersects with toxic masculinity and patriarchal frameworks that says a man who is empathetic and mindful of his actions is weak and undesirable. Unlike characters like Zero and Axl who are action ready, and eager for battle. A mindset that Americans would easily go along with as they share some similar ideologies of masculinity as Japan does.
People are quick to say that Dive is good to X because he gets the most costumes, but those costumes are primarily functional, nothing that expresses a semblance of personality. It's a subtle form of dehumanization, even for a character that technically isn't human, and it sends a subtle message that X isn't deserving of love, either platonically or romantic.
Even Vile gets a Halloween costume, and he's one of the most irrelevant characters in all of Mega Man.
Personally, I don't think Collaborative costumes would count as they're essentially different characters rather than alt skins
