Look, one of the main reasons I like the idea of Mary Jane with spider-powers so much is because it might be the closest we will ever be to have MC2's Spider-Girl (daughter of Spider-Man) in animation. Mayday Parker combines the best of her parents: Peter's powers and brain, along with Mary Jane's good looks and personality. I truly loved the stories of May "Mayday" Parker in comics, and a Mary Jane with spider-powers looks A LOT like her. In "Ultimate Spider-Man", Mary Jane's outfit as Spider-Woman was clearly based on the ones wore by her daughter.Not everyone has to have Spider powers, Mary Jane doesn’t need it, the same way Lois Lane doesn’t need to have superman’s.
Ordinary supporting cast is just as important as the heroes cause it gives us that relatability factor to the heroes which is why Spider-Man is so beloved and very popular.
After this season I am done with the lack of ordinary supporting characters, I am sure the only reason why them Miles and Gwen were there was to promote and sell Toys 100%.
We obviously don’t need damsel in distress, she can be brave or tough who can pull her own weight and she doesn’t need Spider powers for that.
