gay characters that isn't a visual novel :v
Let me introduce you to a little game known as Metal Gear.
Vamp is bisexual, in fact that's why he's called Vamp, not due to his vampiric tendencies, but according to Solid Snake, because he's bi as ****, he was even in a relationship with Fortune's father before Ocelot offed him. In turn that also makes Fortune's father bi. Honestly, Vamp just kinda ***** anyone, Major? Fortune? Naomi? Solidus? He don't mind.
"Pliskin: Vamp is a member of Dead Cell. Born in Romania, his specialty is knives. But I guess you know that by now. When he was just a kid, he lost his family to a terrorist bomb that went off in a church they were attending. His body pierced by a crucifix, Vamp was buried under the rubble for two days before he was finally rescued. During those two days, he survived by feeding on the blood of his family to quench his thirst. That was how he acquired a taste for blood...
Raiden: So that's why they call him "Vamp"...
Pliskin: No. "Vamp" isn't for vampire. It's because he's bisexual... Rumor has it Vamp was the lover of Scott Dolph, the Marine Commandant who accidentally died two years ago. Scott Dolph was also the father of Fortune, the Dead Cell leader."
Volgin is bi but seems to have a strong preference for men, and Colonel Raiko is his lover, in fact that's how Big Boss gets found out, he's disguised as him, and Volgin goes to grope him because he thinks BB is his BF, but it's Big Boss, he instantly deduces that it's an imposter based on his dick being different, proceeds to brutalize Big Boss to the point of permanent damage (If you wear the dude's clothes and mask in the Boss Fight, Volgin even gets pissed off and says he's going to avenge him, for as much of a asshole Volgin is, he liked his bromance).
Ocelot is bi sexual (The bi stands for Bi(g Boss)).
Mantis is aromantic and asexual.
Sniper Wolf is Bi, can fall in love with both men and women.
Strangelove is a lesbian (Though she did mother a child with Huey, so technically bi that seemed to be more pity sex and the fact she wanted a child, not really because she liked Huey a whole lot, she has a very, very, strong preference for women), in fact she loved The Boss, to such a extreme degree she spent years of her life working on a AI construct of her to bring her back and to find out why Big Boss killed her. That's also why she goes by Strangelove, her colleagues used to make fun of her for loving another woman (Peace Walker takes place back in 1974, her fiasco with The Boss was before 1964).
The Boss is also Bi, see Strangelove, but also The Sorrow. Though it's said she'd do whatever when it comes to completing a mission and she has such a high charisma, men and women both fall for her.
Probably others I'm forgetting.
In my opinion, it isn't obnoxious or forced, it isn't played off as bad or a detriment or something to be ashamed of, it's all pretty natural and in some cases, played out really well like in the case of Wolf, Ocelot or Vamp. Thank **** honestly, having that shit done right is a thin line, and somehow they manage to not **** it up, at least in my opinion, idk, I ain't any of that but as someone who isn't, I liked it, each and every one of them are badass lads, like goddamn Ocelot sweeps most of this wiki in pure quality.
The main lads like BB, Snake, Raiden, Otacon (And Gray Fox) and what not are all explicitly straight (Though Kaz while into women, might be a Bi(g Boss) sexual), idk there's kinda gay lines about forgetting women when it comes to BB) but when it comes to side characters (Including some that are even more important than the main ones like Ocelot), there's plenty of LGBT+ what not. And it's been the case for over 20 years.
