Want to see Yoshimitsu with no armour, well go to the customise menu, customise Yoshimitsu, buy the costume for 500,000G and that's it, when you want to battle, press triangle on Yoshimitsu.

Pick yoshimitsu and get you enemy down to
Around /||||||||||||||||||||||||||||||||| / that much health 9/10 and yourself get your enemy behind you the press down square and circle and yoou will stick a sword through your stoamack and hit your enemy directly before you get damaged your enemy suffers a huge amount of damage and dies but you will fall to the ground and will still be alive. Thats how you can beat your enemy with yoshimitsu I thought he was a sucky character at first.
