In a final battle at the Void's base in Antarctica (which he calls the 'Hidey-hole' ... the opposite of the Watchtower, just as COLC, its 'Computer for Obliterating Life Completely', is the opposite of CLOC), the Void claims that Reynolds had actually ingested a super-saturated, exponentially more potent version of the Super-Soldier formula that created Captain America. This was considered dangerous by the government because the Sentry's blood could be used to create more of the serum, enough for the entire world. Several failed attempts were made to kill him. Enraged by this revelation, the Sentry throws the Void into the Sun, telling his enemy that he no longer needs him to balance his own actions of good. The Void promises to return.
