Who Is the Sentry? Robert Reynolds and the Golden Guardian Serum
A joint American and Canadian attempt to recreate the super soldier serum produced the formula that turned Robert Reynolds into the Sentry
The Sentry's origin goes back to a government effort to recreate the super soldier serum, the same serum found in Captain America, Isaiah Bradley, Natasha Romanoff and other Black Widows.
How the Golden Guardian serum was made
In March of 1947, the American and Canadian governments got together to recreate that serum, and they landed on the Golden Guardian serum.
Robert Reynolds becomes the Sentry
Ten years later, Robert Reynolds, a former meth addict, broke into the lab and consumed the serum because he wanted to get high. He didn't. He ended up superpowered instead, gaining the power of a million exploding suns and becoming the Sentry.
