@paragonred asked for Shiro for the meme.
Sexuality Headcanon:
Pretty definitely gay. It’s hard to tell based off his canon interactions since there’s nothing sexual and not much that could be construed as romantic, so that could just be the predominantly male cast surrounding him and also my own biases.
Gender Headcanon:
Cis male
A ship I have with said character:
Sheith, mostly. Shance/Shklance has merits for smut fic but I don’t see it being plausible otherwise.
A BROTP I have with said character:
All the paladins other than Keith since they’re clearly on their own level, but Pidge mostly because they had a few good episodes of bonding. Possibly Lance if they did more with the two of them.
A NOTP I have with said character:
It takes a lot to get me to NOTP something for any reason other than “it’s M/F so I really don’t care” which still isn’t a matter of being passionately opposed, but on that note – Allura, and also Romelle if they decide to lean toward what was (I think?) Shiro’s canon pairing in earlier versions of the show.
A random headcanon:
Shiro always seems like he’s used to being the oldest and most experienced guy around, so it’s no wonder his sense of humor is (humorously) a bit lacking. He reminds me of Mako from The Legend of Korra in that it’s funny to imagine him trying to cut loose and enjoy himself and…not be very good at it. The D&D episode in S6 was great for this.
General opinion over said character:
A strong leader figure with more personality conflicts than I initially expected, and I can absolutely see him as a guy who’d have a mentor relationship with someone younger that would grow into something stronger. That kind of dynamic is central to a lot of the literature surrounding the gay male experience, and it’s annoying that antis like to reduce that to “pedophilia” (actually ephebophilia) and “incest” (actually not, though I’d hate to be the one to tell them about the prominence of self-identified daddies in gay male circles, or what twinks are). Shipping wars aside, I’d like to see what they do with Shiro now that the clone project has been exposed. I’m not crazy about his new all white hair, but maybe it’ll grow on me.
