Unlisted/Secret Brutalities?

[Kratilim]

So here's the thing... I was letting the AI do a tower fight for me as scorpion with the death spin combo equipped. I only have the default 2 brutalities unlocked. But the AI still finished an opponent with a brutality linked to the death spin combo I have yet to unlock.

Can the AI do brutalities you haven't unlocked even when using your preset? Or is it possible its doing a secret/unlisted brutality?

I have also seen 2 that I didnt unlock, not sure but mabye like fatals you can do them before & unlocking them just tells you how to do them..
