It looks like the Kishin Chief model. When I updated the Oni Clans, I added an event where you could receive a unique Kishin Chief unit, a combat-capable version of the Kishin. However, it seems to be bugged in that the Kishin Chief will periodically spawn in or be gifted to other civilizations.
I'm starting to wonder if the culprit may be the Great General promotion -- the Kishin Chief is supposed to provide the same bonus as a Great General, so I gave them the promotion, but I know from recent discussion that that promotion is how Great Generals are spawned. So maybe the game is spawning Kishin Chiefs instead of normal Great Generals (or their replacements)?
I'll have to play around with the mod and tweak the Kishin Chief to try and solve the problem.
Ok, so I'm not going crazy (yet, haha). I went through every single mod I had downloaded, trying to find the unit.
Well, at the very least, it does look bad [synonym for donkey].
