While most notable Soul Reapers in Bleach have at least one battle to show off their ultimate technique, the Bankai, for one reason or another, not everyone had a chance to scream out the epic line during their time in the series. Bankai can be incredibly difficult to acquire, though, as shown in the story's final arc, it seemed as if the majority of Soul Reapers, captains and lieutenants alike, possessed one they were willing to unleash to fight back against the Quincy army.
