Look, all I'm saying is that if you think wanting a character because they're a villain is perfectly fine but also think that wanting a character because they're LGBT+ or a Person of Color is somehow "pushing an agenda" or requires more scrutiny, you really need to re-examine yourself.
Damn, we can't let this die can we.
Also, wanting a character for being a villain isn't just 'he/she bad, me want them' as it can be much deeper than that. Like, Ganondorf isn't just a evil jerk: he actively believes the royalty of Hyrule is screwed up (and rightfully so in earlier 3D titles) and his people are suffering because of it. Sure, he's power hungry and might be worse overall, but when you listen to Windwaker Ganondorf speak about it you realize that there was at least some noble reasoning behind what he was doing.
Contrast this with wanting Ganondorf just because he's black. How basic is that? Who cares that he is the iconic LoZ villain! Who cares how cool and badass he is! Who cares that he actually has a semi-noble motive and in the timeline where Link rats him out he's imprisoned for a very long time before they try to kill him, so his anger and spite is relatable! HE'S BLACK! THAT'S WHAT'S MOST IMPORTANT, OVER ALL OF THAT, RIGHT?!
This is my problem with this line of thinking. It's valuing something so basic and surface-level that it spits in the face of everything the characters actually are. It's acting like that is more important than anything else, which is stupid as hell. Ganondorf could have been any skin color and been just as badass with everything I mentioned above, but he comes from a desert-dwelling people and thus he is black...and that's the least interesting thing about him.
If you have a good character that is well-written, skin color, orientation and gender are things people immediately look past into something deeper than that. This is why characters in fan fiction who's core trait is being homosexual or trans often come off boring, and we can see this in High Guardian Spice right now in fact. If the most important thing about the character is something surface level like that, they are uninteresting, much like people in real life. I have met many people who classify as minorities, and when them being a minority is the most important thing they value, they are incredibly boring and sometimes unfun and even toxic to be around. At the same time, I have friends that I hang out with who fall into minorities, but since that's way less important to them than other things in their life they are incredibly interesting and we can sit down and just talk about whatever and have a good time, with not even anime or games as a medium.
Also, that person who mentioned enjoying Heroes vs Villains already likes something deeper than someone who just wants a character with a minority status. Heroes vs Villains is Good vs Evil, which dives into people's morality and core values, what drives them to save or destroy, and can easily dive into more complicated things like what is truly Good and is the Villain really all that Evil? Wanting a character because of their sexual preference is just that: they are attracted to something in specific, and it doesn't go deeper than that other than perhaps why they are, but these kinds of people rarely care about the 'why' and only that they are they status they want.
Bottom line is this: a video game character being a minority is not a valuable reason for them to get into Smash. Smash has evolved into a celebration of gaming, which is Sakurai's own words, so that is CLEARLY what Smash has become. What about choosing characters just because they are a minority or because their core trait is that they are a minority speaks about the history of gaming? It doesn't. This is true for them being a villain or hero, being smart or dumb, being religious or not...none of that really matters as one individual thing: what matters is the impact that character and their game has had on gaming. Do people love that game and it's series? Do people love that character? Do they want to see them in Smash? Will people buy our game if we add them? Can we make them fun to play?
These are the important questions, not are they a minority. If they so happen to fall into the category AND say yes to all the above questions, then congrats you got what you wanted, but they weren't selected because of that minority status: they were selected because of their impact on the gaming sphere. Frisk could very easily make that happen. Maybe in the future, someone will make a super-successful game that stars a minority character with their entire character is 'I'm a minority!' and the game centering around them being a minority and it rocks the gaming sphere...it's doubtful because people need more than that to find a character or game engaging, but it could happen.
Also I believe you brought up gamer-gate in another post, and frankly you need to go back and do a deep-dive of that because it's not as simple as you think and there was a lot of manipulation and corruption by women in that particular incident. What a ****show that was.
