When you think of Superheroes that would be comfortable with the #metoo movement you might think about heroes like Superman, Captain America, maybe the happily married Flash or Elongated Man. I'm pretty sure though that The Punisher would not be on the top of most peoples list
The issues of sex and relationships are not something that has been seen in most versions of The Punisher. Having Frank Castle's love for his murdered wife and children be the central focus of his motivation. That Frank Castle is portrayed as a hyper-masculine type A personality. A person that is seen by many as a poster child for Toxic Masculinity.
Watching the second season of Punisher on Netflix though I saw a man whose masculinity was strong enough that he had no need to be toxic in order to survive.
As we catch up with Frank in the first episode of the second season he is hanging out in a honky tonk bar outside of Detroit, he is drinking one beer at a time. When a local drunk decides to get a little too touchy-feely with the female Bartender Frank steps in. When she calls him out on his presumption that she needs his help, he apologizes saying that he doesn't like assholes. He never questions her ability to protect herself.
The two of them begin to flirt. As the night ends she invites Frank back to her place for a drink. It is obvious that she wants to sleep with him. As they walk out to her truck she stops for a moment and asks "Promise me you are not an asshole?" Frank really does think that he is an asshole, but is unwilling to lie to her. He replies, "Isn't that what an asshole would say?" At this point Frank senses that she is hesitating and questioning the offer to take him home. He then assures her that if she is having second thoughts then he can simply go back to his motel room alone, and they can never see each other again. She then tells him to get in her truck.
Here we have a simple, but clear example of affirmative consent. As soon as Frank senses any hesitation on her part, despite the fact that she was obviously offering sex earlier, he allows her the option to change her mind.
After spending the night in bed with Beth the bartender, and the next day with her and her son, Frank returns to the bar the next night to see her again. This is when the main story-line begins.
A Young woman named Amy is at the bar selling blackmail material. However the people being blackmailed have discovered this and sent people to kidnap her and get the incriminating material back. Frank realizes that something is going down and busts his way into the ladies room to rescue Amy. He is confronted by two women and a man who are trying to take her. Frank could easily be portrayed as looking down on the two women and go easy on them, but instead he treats all three of them equally. Doing this the writers avoid the trope of being taken by surprise because he underestimates a woman. He treats these woman as equals and not just as sex objects or eye candy.
This is not to say that Frank has become completely touchy-feely. He still treats Amy as someone who needs protecting. But even in this Frank shows a level of self-awareness. Later in the show he explains to Amy if she had been male he would have sat back and watch when they tried to take her.
Does this change the central make up of the Punisher? No, they still have him as someone who deals with villains with single minded violence. Who sees most things in black and white, good or bad. What they have done is develop the character into someone whose masculinity is not frail enough to be threatened by capable woman who are more than eye candy.
