Surprised nobody mentioned his MKD outfit, which wasn't bad. He had two, I wasn't a fan of the Ghost Rider ninja look...
His normal MK
A look was sick, I loved personally costume he wore in the MKDA promo videos doing kata and shooting fireballs. The in game one was good too.
His MKDC was also pretty cool, like a reinvented version of the classic costume.
The mask in MKDC and MK9 are similar but not the exact same, the mask looks more darker(look wise, not color wise) and the scorpion legs on the mask go up around his eyebrows where in MKDC it did not.
He also has more details in the forehead area of the mask in MK9 if you look closely. and then there's the two swords he has which is probably taken from the MKDA concept where he's fighting Quan in the promos/commericals for that game with swords.
