I ve seen KEN gets his Kick assault mainly with the left leg that means he uses a Right Arm-Left Leg combo as main muscle-groups prepared for offence. He is shown as a Right Hander and even I am a Right Hander and working on preparing my left leg to kicks and strength.
Blanca is my favourite. No doubt he's the most powerful guy in street fighter. I remember having won a small gamig tournament with blanca back then when the game was on sega. I frequently used the blood sucking move on opponents. Was expert in that.
Haven't played this game but it looks good. I also recommand this old version with cartoon effects ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zAIcwgwbL9c.html
