In the very first issue of this miniseries, Sentry kills Attuma.
And nobody seems to care.
This series first establishes how ridiculously powerful Sentry is, and is a clear analog to Superman. Like when he beats the snot out of Terrax.
Since no force on Earth can really stand up to him, the real threat here is his own sanity.
We recently learned that Sentry’s greatest enemy, The Void, was little more than a psychological construct. We now see that Sentry is still dealing, internally, with The Void…
Over the course of the early issues of this series, Sentry beats up a whole bunch of villains and saves the world a bunch of times, but all the while, his confusion increases–and so does his estrangement from his human wife.
The adventures are great. Partnering with Hulk in the Negative Zone was a particular favorite of mine. But watching Robert Reynolds, the human, come to terms with being a God and losing touch with human reality is much more interesting. It reminds me a bit of Peter David’s excellent work with Genis Vell, which explored similar themes.
The book relates a series of sessions with a psychotherapist, intertwined with Reynolds trying to discover how he became Sentry in the first place.
It ends with him finally coming to terms with The Void, and figuratively killing it.
Once that’s done, Sentry is able to be a true human–with extraordinary powers.
Turns out, he stole an experimental “Sentry Serum” as a teen and that was the source of his power. The serum was a souped-up version of the serum that created Captain America, and after he took it, SHIELD repeatedly tried to kill him–believing he was too powerful to live.
