Lewis Pullman makes his debut as Robert “Bob” Reynolds, aka The Sentry, in Thunderbolts*. The character is described as being “more powerful than all of the Avengers combined,” a bold claim considering that team has at least one god on its roster. Bob also has a dark side, The Void, a shadowy figure who is apparently invincible and can transport thousands into a dark world where they’re forced to relive their pain and shame.
