Kim was undeserving of Ron, if anything. No, no, I’m kidding, I’m kidding. I kinda had to. This entire issue is just kinda silly. Also, it took me a long time to answer this one because I don’t like spreading negativity. I’m sorry if the reply below comes off as angry or upset - I swear I’m not. I’m just being down to earth. And tired.
If the creators disliked Ron, they wouldn’t plan Kim x Ron from the beginning, and they wouldn’t focus so much on Ron’s character throughout the entire series. You know how Phineas and Ferb is named after Phineas and Ferb, but Candace and Doofenshmirtz are actually main characters with actual arcs and character development? Ron kinda falls into that category, too. Of course I still think Kim is a fully realized character in her own right, but Ron isn’t just a supporting character, he is a main character too, because we spend just as much time with him as we do with Kim, and there’s a lot of focus put on him and his character development.
Because of that, Ron is probably the most developed and interesting character in the entire series, and stating otherwise isn’t even a bad take - it’s just wrong.
Also, let’s get something important out of the way - I am Shego’s age. If you told me to choose between the mad scientist malewife and the minor, I hope it’s not surprising I’d obviously go with the mad scientist malewife, like, this isn’t even a competition. However, some people out there think Shego would choose differently, and frankly, I think it’s quite disgusting and offensive to her character.
(Although it’s okay to headcanon Shego as a lesbian too! Especially if she was your sexual awakening. Trust me, I also started questioning myself because of Shego. Just… don’t ship her with a child, lmao)
Here’s a thing though - if I told people shipping a fourteen-year-old with a woman in her late twenties is bad, and they still wouldn’t have problems shipping it, then there’s not much I can do about it, is there? I won’t go to war over a fictional ship from a twenty-year old show, because I’m an adult with taxes to pay, and internet trolls are just simply beneath me and not worth my time.
Which brings me to another point - I think the reason KimRon seems unpopular in comparison to those other ships you mentioned is simply because it’s old. It’s literally twenty years old, and at this point, I’ve met people who have never even heard about Kim Possible before. (I suppose there’s an argument to make that Danny Phantom is an old show too but the fandom’s still alive, but the truth is - I was there, Gandalf, and Danny Phantom has always been more popular, even back in the 2000s. It’s just how it’s always been. I don’t have a scientific explanation for this one, chief.)
Ship negativity below - skip the strike-through paragraph if you don’t want to read it;
Also, I think it’s funny because I dislike all the ships you just mentioned. I already said what I think about Danny and Sam here. I think Sta//r//co had the biggest potential of being like KimRon but they fell into the same trap as Marinette and Adrien AKA taking too long to get anywhere and tripping over problematic shit on their way, which made those ships super unlikable to me, like, even if I shipped them before, I just can’t anymore, because I don’t enjoy them. And Kl//a//nce isn’t even canon. Realistically, there was Potential, but all they got were very vague/lowkey queerbaiting scenes and that’s it. I genuinely feel so sorry for people who fell for it. But yeah, KimRom is just soo much better than all of those, it’s not even a competition.
Maybe it’s my demi ass talking, but I really love how KimRon started with them being just childhood friends, and then having the most natural friends to lovers development ever. It wasn’t in your face, there wasn’t that much drama around it, it was pretty much perfect. And people are still allowed to dislike it. But I don’t.
I think people who hate Ron are simply bitter their “lesbian” ship ain’t canon, so they feel the need to shit on this clearly amazing, enby-coded character for “getting in the way”, but I gotta be real with y’all - you won’t find good WLW content in this 2000s cartoon made by male boomers. …What you're looking for is in the Owl House, made by openly bisexual Dana Terrace. It’s there, and it’s canon, I promise. Go watch it. It’s good.
