That one sounds very cool.
I actually want to see his LIVING WEAPON from teh MKDA sketches they never used.
The thing puked bees and stuff. That was cool. BUt the weapon ended up being a character...Drahmin.
They should use it for Quan Chi.

He should grab the opponents leg and pull and stretch it to abnormal length. The announcer says "lame fatality.....again"!

It Would Be Cool If In Drahmin's Ending Instead Of Merging With Quan Chi He Merged With Quan Chi's Weapon To Create That Living Staff That Shoots Out Rot Flies
And For His Fatality Quan Would Ripoff A huge Amount Of Skin From There Chest And Then He Would Shoot Out The Rot Flies Out Of His Staff And They Would Eat Away At The Exposed Muscles And Organ Until There Is A Blood Filled Hole Through The Opponents Chest

Quan Chi runs up to the guy lowers his shoulder and rams his head through the guys stomach, impaling the guy on his shoulder spikes (MK4 costume). Quan Chi then stands up with the guy still attached and shakes like a wet dog and the guy goes flying in pieces. Quan then punts the guys head and does a Victory lap doing the Field Goal sign & swinging his fist like Aresenio Hall.

Ok That Was Weird Oh Well I Still Liked The Idea Of Using His Costume As A Weapon

I think he should shoot some evil green magic at the dude's feet.
Then the person melts as they scream in horror!
Kind of like that dude in Roger Rabbit!! Nothing left but a pile of green goo and smoke...
And then Quan Chi laughs!!
or, he kisses you and you die!!

NECK STRETCH!!!!!!

I think that if Quan Chi ever comes back, they should let him keep his dual broadsword weapon, as it was one of my favorites from MKDA, as I think it would make for a fierce Fatality if he simply drew them both and went off in a flurry of rapid swings, decimating the enemy.
They could allow him to remove hands, entire lengths of arms, and perhaps the head, in more than one clean swing. I think it's about time we get to chop someone's head off in three or four pieces, anyway.
