I could be cherry-picking when it comes to X-Men media in how and why they portray female characters but upon watching the video clip ‘What is the Goth Rebel Pixie Dream Girl’ it does help shed some light into the way they’re portrayed. Whilst not always, entirely or consistently the case it still explains a lot of things. Something that not too many make the connection even if it does show up.
Wearing black doesn’t make you Gothic but when the X-Men are almost always depicted as outsiders who do wear black from time to time (most of the time in the X-Men films) with Emma Frost and sometimes Mystique (and rarely Storm) being big outliers the connection between them and the Goth subculture feels subliminal enough to portray some as such. Strangely enough, Kitty seems exempt.
Even though of all the X-Women, she and a few others (including her friend Illyana) wear black the most or more often. That Kitty herself’s a tomboy (even if she wore pink at some point) sort of plays into the points the commentator’s making. Naturally her enemy Emma Frost wears white. The one X-Woman that’s got the short end of the stick the most is the pink-clad Psylocke whose racebending was recently undone.
Whilst not always the case as there are some heroic girly girls or blonds like Psylocke, Dazzler, Emma Frost and Mystique at times. But considering Mystique’s initial introduction as someone who wore a white dress, Psylocke a blatant girly girl and Dazzler being a pop star it’s not hard to see that they seem somewhat warier of them to a degree.
Not necessarily or overtly antagonistic but more in the sense of being too feminine for nerd men to appreciate (yet they themselves don’t want butch women for fear of being emasculated). It makes sense when you realise Kitty gets paraded as the Goth tomboy next door (that too’s imprecise as Rogue’s the one who’s made Goth even though Kitty wears black more often).
It also unconsciously makes sense that Jubilee receives a polarising response. Not necessarily any less sexualised or entirely hated (she’s got fans) but when the character they’re more attached to’s moody and dresses in black (almost a stereotypical Goth) that Jubilee’s unconsciously hated also because…she’s a Valley Girl.
Maybe not necessarily always the case and some X-Men fans aren’t into Goths at all but still makes sense given the context as to feel subliminal enough to make the connection between X-Men and Goth with Emma being an outlier when you think about it.
