These are just thoughts:

A forest stage where vines wrap up the victim and pull them into jaws of one of the surrounding trees for a snack.

An arena with a rope in the middle of the room with large metal doors on all sides. The person that grabs the rope is pulled up while the doors open. Now, what comes out of the doors is the question...

Personally, I'd like to see a re-working of the Prison stage from MK4. Imagine how sweet it would be if, when you throw your opponent into the fan, it chokes sort of like the meat grinder. and once they're all diced up, a few scraps of flesh get stuck to the axle and force the fan to spin at a lower speed.

i already love what deception is planning to offer, with that being said, if i could implement an idea i would do something along the lines of a crush fatality.

After the fight (which takes place on an elevated stage) you knock your opponent down into a pit that at first looks like nothing. However, its just like a car crusher with walls moving in form 2 seperate sides. There would be a small animation of the character trying to get out, but the walls are too high and slippery. As the walls come to a close and crush the helpless lad a squirt of blood shoots up from the force of the walls closing. The walls then move back into position and all you see are a heap of squished guts and organs...thge key to this fatality is a bone crushing sound effect.

Heaven of Fire Stage

Description: The airship is flying through a fiere sky where clouds of flames populate the sky as streaking balls of fire rain down towards the earth. Occassionally a flame lands in specific aread of the airship where a fighter can be damaged if they back into or are forced there, similar to Shang's Palace in MKDA.

In the sky a fiery dragon like creature can be seen flying through the hellish clouds, screeching and howling.

Stage Fatality: A fighter is knocked of the airship at two designated spots and then proceeds to fall to the earth. After falling for a period of time, a fiery dragon swoops down and snares the defeated fighter in it's mouth as the camera folows the dragon as it then ascends back into the clouds with the fighter flailing in it's mouth while screaming in anguish. Then the dragon slows it's ascent as it arches its back and throws the fighter into the air. As the camera folows that fighter, the dragon swoops up from below to swollow the fighter whole as it returns to patrol the hellish skies. FATALITY!
