The Harder They Fall

Reading almost like an epilogue, Captain America #338 found the title character (then John Walker) and Buck (Lemar Hoskins) on assignment to recapture the escaped Professor Power and mop up any other at-large lackeys of the Secret Empire.

The biggest threat the duo faced was Leviathan (accurately shown here with black hair, as opposed to the white-haired rendition from the cover of New Defenders #126).

In the heat of battle, Captain America (Walker) killed Professor Power (who was already at death's door following his defeat in New Defenders #130). Ashamed at what he had done, the patriotic hero questioned whether he even deserved to wear the uniform of Captain America.
