Everyone loves a hero who never gives up in the face of adversity. Who never backs down, no matter what the world throws at them. Well, sometimes the world has other plans.
Whether because a different writer has a different idea for how the character should progress or generally work, or because certain events are just that shaking, some superheroes just feel it's best to throw in the towel. Sometimes they come back, sometimes they stay gone for good.
And these moments can be built up over years to the point where you're just counting down the days until they throw in the towel, or in this case, they come out of nowhere and leave you utterly floored. But, just because you didn't see them coming doesn't make them bad, if anything it makes the act of them quitting even more effecting.
As long as you do it well, a superhero giving up can be the most emotionally resonant scene in your entire series. These moments range in terms of quality, but they are definitely the most shocking moments when our favorite heroes just gave up.
