Carol Danvers: A comic character nobody likes and only has a long running comic series right now because the character is so dull there's nothing to reboot to. Meanwhile Iron Man has several comic runs going as does Spider-Man, Hulk has recently relaunched yet again][for better or worse as the last run was dog shit and the current is leaning hard on the previous Immortal Hulk story], Dr Strange is in the midst of a new run after having died last year or so, and many other characters who fans actually like are doing new and exciting things. Well, most of the time. Marvel is still fairly shit in general but Carol is very much in the lower depths of interest.

Kamala: literally died 2 months ago and was brought back just last week so Marvel could retcon her into a mutant for MCU synergy because the live action version is being used to backdoor mutants into the franchise. Again a character nobody wants or likes. Her recent appearances in Amazing Spider-Man were so inconsequential that when it came time for her to be mourned none of it felt sincere because there hadn't been any actual interactions with the other characters. It was all revisionist reminiscing that was the kind of thing that should have been shown rather than spoken about but Wells has been too busy shitting all over Peter for two dozen issues to include anything else.

Monica Rambeau: The least likely of the three that normies will know because her MCU presence has been squirreled away in the Wandaverse series and beyond that has had no actual connections to the others or her comic versions.

tl;dr this is going to be shit, but then everyone here already knew that.
