Regarding the lack of female presence... I think the worst examples are when they straight up leave off the female characters, like they don't even exist. It seems to happen mostly on the licensing items. Example: in the back of one of the FCBD Marvel books there is a Marvel Hot Wheels add. All the movie Avenges are there (even Hawkeye), but no Black Widow. Just straight up dropped her. And it wasn't like they were only showing the Avengers that there was cars for, since there was no Hawkeye.
Hasbro has been doing a great job getting more female toys out there. Almost 2 per series at this point in Marvel Legends! And there has always been great diversity in the Minimates brand. Other toy lines can't make the same claim though.
