Suggestion; a "helpless" setting (on/off) where when on characters that are "full" become unable to do anything and can be- Spared, Captured, or auto popped with sharp object.
The same could happen to the MC and they may become "toyed" with(centar/gob) looted(bandit) and other such depending on the enemy.
(i have other ideas but I'd like your input on this first.)
