What should MCU avoid when writing Danver's interaction with Rogue?
Brie Larson would have to walk a tight rope against MCU fanbase's negative perception and also fulfilling a significant arc in Marvel history that both leaves Danvers depowered and antagonizing some beloved "heroes-to-be".
Carol will not be beefing against a high schooler
Not entirely sure if this counts as a theory-- but I would imagine that Rogue shouldn't start out as a student (compared to the original FOX franchise) but as a villain in reference to her comic origins. In the comics, Rogue was also already mature when she takes down Captain America before being recruited by the X-Men. Inde Navarette is also older than Sadie and Kit. Rogue's maturity may be disorienting for people who would want to see Rogue as Scott and Jean's little sister, but she's romanced with Gambit and Magneto already ahead of the two lovebirds' marriage story toiled with Wolverine, Emma, and Pryor. Carol will not be beefing against a minor from high school.
Kamala Khan and James Rhody are involved
Carol Danvers would need a rationale to return to Earth again. This conversation would have to form elements that comes after the conclusion of Doomsday and Secret Wars. The simplest idea would be that somehow Danvers is convinced to retire. Including a romance with War Machine. Something tragic may happen to Kamala that would pull both Avengers veterans out of retirement. A personal touch I would put into this is that Kamala somehow knows that Carol is being targeted. Then she uses her light-based powers to "shapeshift" into Carol to draw Rogue out. I hope the MCU doesn't forget that her powers aren't two-dimensional. At Kamala's MCU conception, she should be using her powers like the Green Lantern instead of limiting them to her comic counterpart.
Rogue's change of heart
So, a bit why I'm writing this is that I grew watching Rogue as a fan. Carol comes as an afterthought in her development. We know Carol's powers are permanently embedded into her by now. But my exposure to Carol has mostly been that she's quite of a zealot already before Brie was cast. And my honest thoughts behind what I've seen Carol do in the MCU somehow aligns to the idea that Carol is still somewhat self-righteous. Brie as Carol Danvers, I hope finds a breakthrough in the next leg of MCU's Mutants-Marvels arc. As much that I haven't been a fan of MCU's direction for Captain Marvel, the comics really and still don't help her much either (like she was mean to Miles Morales, then when she shows up anywhere else, writers only reduce her to a muscle). I concern about how Carol being depowered could be swayed away from gratification by some of MCU's negative fanbase. And also, I'm still uncertain on how to make Rogue's change-of-heart become convincing enough. Rogue could feel bad depowering Carol but probably injuring Kamala would actually make her regret her past more convincingly. Like I actually don't think I'd feel that bad if I stole Superman's powers. But that's just me.
