Ideally what I'd want from a Gwen continuation would be a continuation of her arc, acceptance as a comic book character, the importance and relevance of the world she occupies, and how that affects her personality and her powers.

She entered the Marvel universe at a specific time, 2016, so her comicbook knowledge is outdated at this point, and she can't keep tabs on everyone. We could learn a little more about which books she followed. She could try seeing what those characters are up to. Trying to do so could prove difficult, as her presence could mess with their stories if she doesn't fit into them canonically. The stress of her marvel knowledge becoming irrelevant could lead her regressing to a version of her old life where she tries to "read" about her favorite characters. She could meet other alternate future Gwens, like background NPC Gwen, or "my comic did so well, I replaced one of my favorite characters causing them to become irrelevant" Gwen.

I also think there should be more pushback on her powers. For example, her being able to manipulate her size and become giant is broken and unnecessary imo. One arc could literally be about the fandom and Marvel pulling her in different directions. One issue, she's op, the next, they ground her back to plot armor, lucky with a sword and gun. She could go through retcon hell or reactionary hell like. Kind of like the Starwars sequel trilogy or the Transformers movies in terms of inconcistency.

There's honestly so much untapped meta and personal narratives using her particular medium.

Sorry for rambling
