Well I wouldn't take it personally if you skipped my Galatea arc.
But you'd miss out on some deep dives into Karen's character and history.
So, okay, the way I'd approach the Galatea thing.....most versions of ancient Krypton have a clone war that decimated civilization and left a deep stigma against cloning and genetic engineering right? And Karen would share that bias. She doesn't like "copies." And where is she? On a whole world (a whole universe!) that's a copy of the earth she knew, surrounded by copies of people she loved. Sure, it's alternate dimensions and not clones, but in a illogical, emotional way, it *feels* the same. And that's part of why she keeps the Kents at arm's length despite getting along with them, it's why she struggles to put down roots. And to make it even worse, here, *she* is the copy. It makes her feel like a clone, and is something she'd lowkey struggle with that ties into the other aspects of the "imposter" themes that run as undercurrents in her personality.
When she's confronted by her own clone? That's a lot for her. That forces her to deal with these issues in a direct way.
As for Galatea, she'd be taking all these imposter themes and bringing them to the fore. What does she want? To live her own life, free from the circumstances that made her, free from the shadow of someone more popular (her creator, Ultra or Max or whoever). Sound familiar? Just like Karen, right? But in this, we flip the typical Clark/Bizarro dynamic; Clark wants to help Bizarro grow and be the best person he can, but Bizarro's ability to change is limited. Here, Galatea wants to grow and change and improve, but is Karen willing to help?
It's not a story that puts Karen in the best light I admit, but I don't believe *every* story requires the hero to be the very definition of positivity and progressiveness; they need their flaws and blind spots too yknow? Dealing with her biases gives Karen something to work on and some character development and the arc gives her a chance to fail (every hero needs to lose sometimes). And over the long-term, we'd maybe have a chance to see Galatea build her own life...which is full of possibility. What if Gal decides that, yknow what, that Vartox guy is pretty great, and Maxima comes looking for the home wrecker at Starrware, thinking it was Karen and not Gal? What if Gal decides to solve world hunger by terraforming huge parts of earth? Or the moon? Countless fun "mistaken identity" stories there, once Gal eventually evolves beyond straight villain status (if she does, maybe her and Karen end up hating each other so much it's always violence when they meet?).
None of this is to change your mind or anything, but you gave me an opening to elaborate on my ideas, so......
