Just a reminder, in case it was somehow unclear, that AI doesn't, and cannot understand.

I asked for a bat-pony. The first two are from an E621-trained checkpoint, so okay, fair point. I also tried, since Equestria-at-war calls them thestrals, for a thestral equine - 3rd image.

Switched to the v6 pony-trained (derpi? I forget now) checkpoint, using the term bat-pony again, same everything else and get this 4th image ... along with several brightly colored but recognizable bat ponies

Fun if I have time, but it's not really even nightmare fuel, just bad copy-pasta.
