Make up some enhanced brutalities for characters. Here's one I made for Scorpion...

Scorpion would start off punching and kicking you as normal, but you could see your victim's face start to bruise and bleed, and when you get kicked in your stomach you can hear ribs breaking. When Scorpion uses his sword you see cuts and gashes starting to appear. When he's done using the weapon, he impales it into the victims stomach and he starts backing up screaming in pain. Scorpion then throws his spear and brings him back to him and twist the sword and jerks it out and cuts off the victims head.
