Info édition : TPB. Collects Dial H For Hero (2019 DC) #1-6.
Résumé: When teenager Miguel Montez was ten years old, Superman saved his life--and since then, he's spent every waking hour trying to recapture the thrill of that moment. Unfortunately, life in the sleepy town of Devil's Canyon, California, is hardly an adrenaline rush--especially when you're stuck working at your uncle's mayonnaise-themed food truck.
But Miguel is about to get more excitement than he can handle. When a mysterious rotary phone appears in a life-or-death moment, a strange voice comes over the line saying that it has the power to transform him into a never-before-seen costumed champion--all he has to do is dial "H"!
Suddenly, Miguel becomes a superhero--or, more specifically, a bunch of different superheroes, with each new "call" lasting a single hour. But he also becomes a target--because the villainous Thunderbolt Club knows all about the power of the H-Dial, and its members will stop at nothing to get their hands on it. Now it's up to Miguel and his new friend Summer to get the H-Dial into the hands of the one man who can protect it--a certain Man of Steel!
