4. Hourman

Drug of Choice: Miraclo

Rex Tyler dates back to the Golden Age of comics, and is one of the earliest examples of a superhero powered by pharmaceuticals.

Rex invents his own supersteroid, a pill called Miraclo that gives him one hour’s worth of super powers  that include strength, speed, invulnerability, agility, the whole suite. Unfortunately, he can only take it once a day. So Rex can only be super for one hour per day. I guess he waits in the car while the rest of the JSA finish fighting Per Degaton, The Fiddler, or whoever, but he does eventually manage to kick his addiction to Miraclo.

I’ve always had a soft spot for Hourman, mostly because I love Rex’s successors. But Rex is pretty great, too.

And with all he does with his single hour of power, it appears that his real superpower might be time management.
