the lone hero vs the collective

I've recently reread Frank Millers "The Dark Knight Returns and Paul Popes "Batman: Year 100". Batman is the typical lone hero. A vigilante and a dark knight. Therefore I think it's kind of interesting that Frank Miller have almost neoconservative views and Paul Pope have libertarian views. Paul Pope even let Ludwig von Mises have a part in his "Berlin Batman". Why is that interesting? Because both these political and ideological movements contains elements of the classic hero cult. People should strive to become heroes. This goes to the extreme among the objectivists and their "worship" of the Randian hero - the entrepreneur. Bruce Wayne is almost an Ayn Rand like hero. This made me think about the lone hero and the collective in popular media like comics and movies. I haven't been able to find one movie or comic book where a collective of people have been the "heroes". But in some movies the collective is the threat. Just look at the Borg in Star Trek or the space seeds that take over human bodies in the Invasion of the Body Snatchers. It's kind of ironic that most horror movies work just because the characters in them choose not to cooperate against their common enemy. Instead they usually choose to work alone with the now classic comment - let's split up! We all know how that ends. The result is plenty of death and one surviving hero. Even in Frank Millers 300, which sounds like it's about a group of people cooperating to fight a common enemy, there's a hero - King Leonidas of Sparta. Sometimes I feel like it would be really refreshing to see a group of people cooperate on film or in a comic book and actually have some success in doing so.
