I don't know why they insist on mummy Ermac. Sure, it fits another archetype, well done. But he is boring as fuck now to look at. MKX Ermac made me gag everytime, disgusting shitty design.
Make him at least SOMEWHAT look like a ninja again, and none of this floating nonsense please. Have him be grounded and only going into float mode for certain moves (telekinetic slam etc).
He could be DLC if they end up doing 3 Kombat Packs like some people think, but his mask is one of Skarlets as far as I'm aware (with the black X on it), and his costume isn't particularly that detailed. It's very similar to one he had in MK9, so maybe it's an unused variation of that.
Basically, don't get too excited.
