Bare with me I'm just thinking of random stuff you can do with Yoshimitsu.
Also I'm going by game's controls not this RP/LK nonsense (even though I know what it means).
I am going to asume you are on LEFT side.
Yoshimitsu's Flash (Style Points)
Left, Circle + Square
Yoshimitsu's Blade
Right, Right + Triangle
(Best when Yoshimitsu goes pass the ai)
Harakiri
Down, Square + Circle
Running Harakiri
Right, Right + Square + Circle
Harakiri into ... I forgot name (You get dizzy)
Down, Square + Circle, Left + Square + Circle
Energy Charge into Lifesucker
Sidestep, X + Circle ... Square + Circle
Deathcopter
Right Up + Square + Triangle, Left.
Got told to convert... so.... CONVERT

Left, 4 + 1
Yoshimitsu's Blade

Harakiri into ... I forgot name (You get dizzy)
