I read an article last month that was going around from an alleged anonymous “insider” at the original TFA merchandise discussions with Disney that basically said that the companies all went in with lots of ideas for Rey merchandise or stuff that had her front and centre (seeing as, you know, she’s one of main characters of the film) and they said that Disney execs said boys don’t want to play with girls, it’s all about Kylo Ren basically. Now take that with a grain of salt but it sounds about right tbh.
I know off the top of my head she has two funko pops (one with goggles that’s Hot Topic “exclusive” and one without which you can get anywhere), legos, a black series figure, several regular figures including one in her outfit from the end of the film with Luke’s lightsaber and two elite series 6" inch die cast figures (one without the lightsaber that was released before the film and one with the lightsaber after the film) that are
Disney Store exclusive. I’ve also seen girls pjs with her on, mugs, bags, mens and womens t shirts with just Rey on here in the UK, she’s in the Disney Infinty game and she’s being added to new Star Wars monopoly rerelease. There's probably more stuff as well but that's all I can think of right now.
Is it enough? Of course not, but hopefully Disney will have realised their mistake and release even more stuff with her on soon like they should have done in the first place.
As for Marvel, I’ve noticed they’re really pushing Natasha merch for Civil War, which is good. I just hope they do the same for Wanda and Sharon too.
