Its the Deadliest Warrior on JB sweet!!!! love that show ok granted the Pirate was deadly in large numbers and maybe one on one with another pirate or foe but you pit him aganist a ninja,ninja wins hands down due to the fact the ninja isnt going to let an enemy see him plain and simple so BAM! ninja wins hands down.
I'm going with the stealth ninja. Something about not being seen and capable of killing your adversary without them even knowing your there. That and the Big Ass sword.
