I have a feeling that this is going to be a controversial post. I really don't want to start a discussion about identity politics or race or something like that. CBR does not need that sort of thing. It's not good for this message board or the comic book community as a whole.
That said, I think this is a question worth asking. Recently, I saw this video from Diversity & Comics, a YouTube channel that often reviews comics, but tends to whine a lot about identity politics. I usually don't agree with his reviews, but then I saw this video arguing that Riri Williams works better as a villain rather than a hero. And honestly, I think he's right.
Now, I've got nothing against Riri as a character. I'm glad Marvel is rolling the dice, creating new characters for new roles. Bendis has, historically, been really good at writing teenage characters. However, I personally find Riri to be boring and unlikable. She seems to have this pathological, self-centered need to be relevant in a way that just doesn't seem that heroic. She's not nearly as endearing as Gabby, Nadia Pym, or Kamala Khan. I'm not saying it's too late for her to become that endearing, but I think if Marvel really wanted to make her interesting, then making her a villain would be a good way to do that.
Marvel has made a considerable effort with respect to crafting female heroes. That's all well and good, but what about female villains? I think they need to be part of the equation too. Having only men or male figures be villains just creates this unequal dynamic that becomes predictable and bland. Sending Riri down the villain's path could really mix things up. She could become what Dr. Doom once was, but younger and with less baggage.
When you think about it, Riri does have a bit more in common with Dr. Doom, personality wise. She's very smart. She knows she's smart. She's basically capable of doing anything. She gets bored easily and makes a lot of issues about herself. She has an ago, but not in the same way Tony Stark does.
Also, I think it's inevitable that at some point, Tony Stark will return to become Iron Man again. He's not even dead. He's just in a coma. He will come back. It's only a matter of time. After that, though, what happens with Riri? I think she has the potential to be Dr. Doom for a new generation. I think being a villain would make her character and her story more interesting.
That's just my opinion, though. I have a feeling a lot of people disagree with me on this. Again, I don't want to turn this into another discussion about identity politics and diversity. This is just an idea I think is worth sharing and discussing. Riri Williams clearly has a future at Marvel. But it's not yet clear just what that future is and I think her future as a villain is more promising.
