Sentry both idea and character lay dormant for 4 years, until Quesada and Bendis made sweet sweet love in the backroom of a seedy bar and then went to Vegas and got married and as a wedding present Quesada gave Bendis the Avengers and then Bendis killed the Avengers and made a new team. Bendis plucked Sentry out of obscurity and thrust him back into the spotlight (as he did later with the Hood, and probably some other characters) and essentially set him up for failure. Because of his resurgence into the limelight, Paul Jenkins was called upon to craft a new solo story detailing the origins of the Sentry. Which he did.
And here’s where it all went wrong. Now they had to explain. And it’s painfully obvious that they stopped at the first idea. “Really really really powerful super soldier serum” Is just below “Wolverine’s son” as stupid origin.
Sorry Daken, it’s true. It’s really true.
Apparently now he could move one second ahead in time, or something. That doesn’t give you super-powers, or give the the power of a million exploding suns. That just makes you slightly early for things.
Later his powers were revealed to be similar to the Molecule Man’s.
Still later, shortly before his “death,” he (or the Void) was revealed to be the Angel of Death, or some biblical power of that fashion.
One second after this revelation it was clear that nobody knew what they were talking about, and that the Sentry was truly a Void–a creativity void. You can tell when the wheels are spinning, and this had the stink of a group of writer’s sitting around a big table with coffee and donuts wondering what the hell they were going to do with the Sentry. He’s the Void! He’s a guy named Bob! He’s powerful, he’s crazy, he’s weak, he has a wife, his wife’s dead, he’s easily corrupted, blah blah blah…he ceased to be a character. He became a series of origins and a costume with nothing to hold it up but quirks and the vague hint of “mystery”
