Thunderbolts* came and saved the day for fans and Marvel Studios… at least from a fan and critic standpoint. While the movie did not achieve a significant box office run, it brought back the storytelling that fans around the world had been craving. The ragtag group of anti-heroes received a favorable response from the audience and critics, and gave us some fun characters to look forward to. Nonetheless, Lewis Pullman’s Bob was the breakout star of the ensemble, and he will return for Avengers: Doomsday.

Pullman’s Bob, aka Sentry, who was being trained by Val (Julia Louis-Dreyfus) to replace the Avengers, was the heart of the film. In the post-credit scene, we see him with the rest of the gang, but depowered, concerned he could reawaken his darker half if he uses his abilities again. Pullman was reacting to the reported trailer release of Avengers: Doomsday, playing ahead of Avatar: Fire and Ash, in a new interview with ScreenRant, “Oh my god, I can’t wait to see it. I didn’t know that!” he said, before affirming, “I haven’t seen it.” However, the actor stressed that “I’m so excited. I think I’m as excited as anyone else is.” He went on to add how “it’s such an incredible team and a remarkable ensemble. There’s a lot that I am looking forward to seeing.” As he is excited to be back as part of the cast, he concluded:

“I love Sentry, and I love Bob so much, and so I’m just riveted to be able to get to step into his shoes again.”

After Sentry’s dark display of his powers in Thunderbolts*, it is unclear how Bob and his alter ego can come to terms before going up against the big bad Doctor Doom (Robert Downey Jr.). Fans have been comparing the power levels of various heroes against Doom, and a showdown between him and Sentry is expected to be glorious. How it unfolds remains to be seen.

Also, Chris Hemsworth as Thor, Anthony Mackie as Sam Wilson (aka the new Captain America), and Tom Hiddleston as Loki are also in the cast.
