Chain Breaker. Punching Machine. Two Punch Killer.

Bunker Riley has been a successful championship boxer for no longer than seven years. Before, he suffered from two heart attacks during his time as a marine in enemy territory that which led to a military accident.

His weakness became his greatest strength even though Bunker suffered a great deal over his past.  In each moment of loss, he faces his real enemies with only the fist of steel making sure the sorrow doesn't infect him.
