I know the second set of question marks is the 1st hidden kombatant, but what's the first set of question marks?

Edit- I think the specific ones are "perform every fighters hidden finishing move" and unlock the flesh pit costume.

I have the flesh pit outfit. I haven't done every fighter's hidden move though; that must be it.

I figure it's worth a mentioning that you only need babalities for this trophy. I was missing a few pits, and it still awarded it.
