He might have some afflictions, though. Until he heals them, of course.

I know that it's not possible to use a doom horror after its captured because after the first battle it will disappear, however I have another idea.
Would it be possible to capture/charm/control one of these special doom horrors and then have it rest peacefully inside a castle thus keeping it from reappearing ??

Also if one of these special doom horrors are placed on the map in a province which cannot be reached... will that also prevent the creature from appearing ??
