Mysterio easily. Just sucks no matter what they do they are gonna get the scarecrow comparison.
This shouldn't be the case.
Far From Home:
The new direction for Mysterio is all digital. So, it should be pretty easy to differentiate that side of things from the hallucinogenic side of Scarecrow. Of course, that's assuming that they go with the digital direction from the movie. But, yeah...if they keep the new Mysterio as canon, then I don't think any comparisons should be drawn to Scarecrow.
