Dig it, hep cats: The Challengers of the Unknown.
They have one of the ass-kickin’est hooks in comics:
A giant monster threatens Mumbai! Space aliens are kidnapping thousands of people! Mad scientists have united to create an unstoppable robot army! Armageddon is nigh!
Who can save us?
A godlike man with amazing powers?
A space cop with a magic ring?
An Amazon princess?
All we got is four regular guys. No super-powers, no magic, no legendary gods. All they have is toughness, smarts, and courage. Lots and lots of courage.
It’s an inversion of the Superman power fantasy: rather than the readers enjoying the idea of being greater and more powerful than the rest of the world, the Challengers revel in the idea of a world that’s big, powerful, and nasty, but where the good guys win anyway.
They’re about guts and brains beating out overwhelming force, about feeling small in the face of a dangerous and powerful world and fighting like hell regardless.
The only old-style Challs story I own is an issue of the Super-Team Family where they travel to the Bermuda Triangle and save Henry Kissinger. It was beautiful seventies cheese.
The idea of the Challs has been revived three times in the last fifteen years. The first, the Jeph Loeb/Tim Sale miniseries, tried to update the original team, to mixed results. The second, by Steven Grant, was an X-Files-esque series about the paranormal. The third, by Howard Chaykin, was a weird political satire unrelated to the original idea. All of them were worth reading.
But dammit, I like the "Four Regular Humans Versus Time-Travelling Dinosaurs Bent on World Conquest" approach. There has to be a way to make that work again today. Dang it.
