Question stage fatality..?

I know for sure its (F,U,U+1) But how exactly do you perform it? and i don't mean the stage variation of positioning it requires, but do I hold block for the foward or block after the foward? Or do I not even block at all?

what do you mean stage variation?
sweep distance; try holding block up until you push 1.

I meant that as in... When you look at the distance required to perform it, it says (varies) so Im guess it varies stage to stage...
so do you mean its sweep for all stages?

Best and easiest way to do it IMO is to buffer the input from a jump in, either that or you can buffer it during turning invisible or during a smoke towards etc, just land close to him and itll happen man

Currently none of the stage fatalities have a 'varied' distance. All the stage fatalities are performed touching the opponent. This may not be true in the future, but for now, it is.

They say varied, but they're all done from close distance.

Hold block doing the directions, then let go of block and press 1.

ezest way to do it is hold block f u u let go of block then press 1

Another alternative would be inputting F, U, U, and press 1 as soon as he lands on the ground.
