SENTRY #4 MAIN CVR

THE WORLD'S MOST DANGEROUS HERO FACES HIS BREAKING POINT! NEW YORK is overrun by a terrifying crystalline entity - and only the SENTRY, returning in full force alongside the FANTASTIC FOUR, stands between the city and total annihilation. Can BOB REYNOLDS unlock the truth behind the crystals' impossible evolution before they consume everything in their path? And will the combined might of the SENTRY, REED RICHARDS, SUE STORM, JOHNNY STORM and BEN GRIMM - and even the HULK - be enough to stop a threat that adapts to every attack?
