The Sentry has been Thunderbolts*'s biggest mystery, and we finally have a full breakdown of the McU's take on the character following this week's fan screenings.

As expected, Valentina Allegra de Fontaine is responsible for The Sentry's creation. The CIA Director has been using O.X.E. to experiment on people in the hope of creating a powerful new superhuman, and "Bob" is revealed as the only survivor.

The Thunderbolts encounter him in the abandoned base from the trailers, and he eventually crosses paths with Val in the former Avengers Tower (now The Watchtower). She says all the right things to sway him, but gets a taste of the darkness within when, like the Thunderbolts earlier in the movie, she touches him and sees a dark vision from her past.

Despite that, Val forges ahead and has Bob suit up as The Sentry, a superhero she's designed from scratch.
