You did such an AWESOME job on those first 2, now I want one with ALL of my favorite ninjas with "NINJAS RULE!" written on it...they are:
Hattori Hanzo (Samurai Showdown 4 ver. if you use a sprite)
Galford (same as with Hanzo on the sprite)
Shizumaru (though I know he is NOT a ninja, he is my fav char from the SS series...please use his SS4 ver. sprite as well)
Kenji (same as the one you used before)
Ibuki (ditto, but use the sprite you used in the Gambit/Ibuki pic)
Mai Shiranui (preferably here KoF XI ver. sprite, but anything after KoF2k will do)
Nakoruru and Rimururu (again, I know they aren't ninja, but I feel they'll fit the theme...use their SS4 sprites as well...in Nako's case use Mamahaha)
Andy Bogard (the ver. of him with the full-body white and black costume sprite please...I think it was 2k1 or 2k2)
Hokutomaru (from Garou: Mark of the Wolves)
Guy (he IS a Bushin Ninja after all...and one of the COOLEST additions to the SF roster...still wondering WHY he was in SF3 /:))
Psylocke (need I say ANYTHING here
)
Cammy (not sure if she is considered a ninja, per-say, but again she fits the theme...if you can find a KoF-ish sprite of her, use that)
Malin (in case you are not familiar with her she is from KoF 2k3)
Sub-Zero (use Binho's sprite from his NEWER ver. of his Sub-Zero)
That's it...let me know if that's too much for you...
EDIT: Forgot one...Jon Talbain...don't remember many differences between the different versions of DS, so I'll just say to go with his DS3 ver. to be on the safe side...)
