Excitement was already high enough when Marvel announced they were developing a Thunderbolts film, featuring a team of anti-heroes. However, the movie may have just gotten better as rumors arose that Sentry, one of the most powerful characters in the Marvel universe, could be the antagonist in Thunderbolts. Fans of Marvel comics have been itching to see Sentry on the big screen since the Marvel Cinematic Universe (MCU) was first created, as an extraordinarily powerful superhero and supervillain and one of Marvel’s most unconventional characters.

In the comics, Sentry had quite a tragic backstory. He was a lonely middle-aged man named Robert Reynolds who was suffering from addiction. After breaking into a laboratory seeking a high, he ended up injecting himself with the Golden Sentry Serum. The serum was an attempt to recreate the Super Soldier Serum, but magnifying its effects by a thousand. As a result, Reynolds became Sentry, a man with the power of a million exploding suns. The full extent of his power is unknown, but he is believed to be nearly omnipotent.
