RIPTOR- first put in a jurassic park call like in this video https://www.youtube.com/watch?v=e5Lx9bH0n1E
and maybe the infamous toe tap like here https://www.youtube.com/watch?v=WfWJGFhg0cg then for the final kill have the or a pack of raptors surround and then all feast on the fighter but not overwhelmingly gross.
Saberwulf- to pay omage have him shake the liver like a rabid dog like KI1’s Supreme animation(AWSOME) or the slap up against the screen
Orchid-Have the firecat lunge but cinematically like this https://www.youtube.com/watch?v=T0kzdu_wTM0
Cinder-have him summon fire from underneath wafting his hands up and just looking mean while hes doing and as the fire goes down they sink into the firey abyss like ki1 1:40 https://www.youtube.com/watch?v=xj-1M3nMKuM but with style and more modern
RASH- Comedy has to engulf rash’s ultimate,how about rash busting out a 80’s boombox challening to a dance off while the opposition looks confused and Rash looks on with his arms folded and rolling his eyes and just picking up the boombox and using his mega big punch knocking it off the oppositions head so hard and knocking them outcold but being funny with it
Thats just a few ,throw out some ideas
