Everyone has their own definition of a superhero. Some people might see them as invincible powerhouses that can overcome any challenge. But many superheroes struggle with their mental health, and the Sentry is one of the best examples. Sentry #1, written by Jeff Lemire, sees the Golden Guardian return in a new series. Yet the return of Sentry also heralds the return of his dark alter ego, The Void. Sentry #1 brings up the idea of whether being a superhero can turn into a drug, so there’s a lot to be intrigued about.
