What about having non-cinematic finishers? Like doing a certain shadow move when opponent are in danger mode and it turns out into a finisher. Like Jago do a shadow dp and the victim disappear from the screen. Cinder does a shadow inferno and the victim stand burning into the ground. Gargos has an ultra finisher that looks like a no-mercy where he launch with the victim in the air and smashes it into the ground.
@Ravan86 has plenty of ideas but no-mercy

It could be more simplistic like an super shadow move through enemy danger state.
