A Decimation tie-in miniseries.

When the fate of the world hangs in the balance, how much do you trust someone who hides behind a garish costume, has freakish super-powers, or keeps their real identity a secret ? That was the question posed by the government's Office Of National Emergency. Their answer? Create their own super-team, a team the O.N.E. agency can control. And so, the Sentinel Squad program was initiated, where the 80-foot-tall mutant-hunting robots known as the Sentinels would be redesigned and rebuilt for this explicit purpose. But this time around, the Sentinels would be equipped with human pilots.

Collected in Sentinel Squad O*N*E: Tin-Can Heroes.
