Motaro has a lot of techinichal issues, remove the xrays on him or make a common generic xray for every character to perform over him, I dont care, he still has technichal problems for example.
Jax's gotcha, air gotcha and other moves are impossible to do on a character of the size and form of motaro.
Quan Chi has a string in that he crushes a skull in your stomach, that one would look really weird on Motaro since he put you in his back after crushing it.
Noob's teleport slam on Motaro would look dumb lol
There is a lots of other stuff, NRS would have to add generic punches and kicks to every character and disable some specials to make it possible and it would look really odd and boring.
There are 2 options:
And I prefer the first one.
In UMK3 Noob saibot teleport move never connected...They just have to make all the moves you listed not possible on Motaro as they did in UMK3....That would be an advantage for Motaro and will make it more challenging for us. Pushing us to think of other ways to defeat him.
