Okay, we seem to be talking past one another, sorry about that.
So the original incarnation of Ivy was straight (at least by default), introduced in 1966 according to wikipedia. After Harley Quinn was introduced in Batman: TAS, they became friends in the episode Harley and Ivy, continued the friendship in the sequel series New Batman Adventures, then subtext started by at least 1998 that they were more than friends.
That's what I'm talking about with a change in sexuality. Adding "Oh, this character's bisexual" 30 years after creation is a sudden change towards 'representation'.
And apparently we disagree if it was for the better, which is fine, but at the very least, I think we can agree that it was done for story and character reasons, not just scoring woke points.
Ultimately, that's something I'm interested in finding: times when they made an established character 'more diverse' or such, but it made for a more interesting story, or baring that, was at least for story reasons.
Honestly, from looking at what I've seen, it seems that it used to be done sometimes well, but now is never good. Hopefully, though, the list might be useful in talking with people with just a foot on the woke train: point out that sure, it can be handled well, but none of the recent examples do the characters justice.
Huh, really good point here! I really like it on a literature level here too.
I do agree with this. Tragic scientist is how I grew up with Mr Freeze.
