Bob Reynolds -- the original Sentry -- is one of the most powerful heroes in the Marvel Universe. After consuming a prototype super-serum, Reynolds is gifted an incredible suite of powers. Fueled by solar absorption and dependent on his mental state, Sentry's powers are near limitless. When Knull -- God of the Symbiotes -- attacked the Earth, Sentry met him in orbit to do battle. Knull promptly ripped the Sentry into pieces, leaving him dead and the world without one of its most powerful heroes. Luckily, it's impossible to keep a good superhero mantle down for the count. Now, random people across the universe are manifesting the powers of the Sentry and experiencing flashes of Reynolds' memories. Sentry #1, written by Jason Loo with art by Luigi Zagaria, colors by Arthur Hesli, and letters by VC's Joe Caramagna, brings readers a new entry into the legacy of the Sentry.
