Behold, from Honkai Star Rail: Wraith wardens! Partly prison guards, partly exorcists.
Technically good guys, but they have a track record of getting possessed or killed, and in gameplay terms they're strictly enemies, so they still count as zako. Gameplay-wise, their only gimmick is that their first hit inflicts a debuff which will stun you if you get hit again.
They were introduced in version 1.5. Part of the story in this version involves a bunch of them getting possessed, so in the area leading up to the boss you get to see a bunch of them on the ground, presumably unconscious.
Here's a timestamp of the relevant section, including a fight against some.
They also make a return in the most recent version, 2.4! This time, the heroes get caught up in the middle of a jailbreak. There's a short-but-sweet cutscene where a superior discovers one of their bodies, and attempts to rally them, while the camera cuts to show us that there is nobody left to follow her orders.
Once again, relevant timestamp.
Unlike last time, we can be pretty sure these ones are actually dead.
I plan on making another post for Genshin, because that has many more zako-esque enemy designs, but ironically it's made it all the more difficult to make something both comprehensive and reasonably brief. Maybe I'll just have to make one for the Fatui, and another for the Eremites? Who knows.
