There are already gay superheroes in Marvel unfortunately.
hence Marvel’s present second rate status.
Marvel USED to be legendary in their incompetence in moving from pages to screen.
Once Sony too over, Spiderman was their first success. (anyone remember the FIRST spiderman trailer? the helecopter caught in a spiderweb between the twin towers.)
Homosexual characters = marketing flop and money wasted.
The highest-profile gay superhero is the current version of Batwoman, who's now featured in Detective Comics.
