Lots of tatoos yes, but he's not an asian, he's evil, main bad guy...he is a Dark Jedi trying to bring back the good old days of the sith, he is powerful with the drak side, but uses a method of combat that destroys his opponent mentally and physically, Yukasa is an extremely powerful ilusionist, he fights by tricking his opponent into thinking there are more of him, or going into their worst memories and plays over and over again in their head, he has many methods of torturing his prey, but he will stop at nothing to destroy the jedi and become more powerful, he also has the ability to drain the force completely out of an enemy, adding to his power with the force, and leaving them with less than a minute to live...
