Just watched the episode again, realized something."A ninja cannot defeat a samurai".Oh, poor Volt. Pirate, you idiot, PIRATE. If you'd dressed as THAT, then you would have stood a chance!
being a registered samurai myself i would like to believe that samurai's would always win against ninja's but the fact is that ninja's are excellent at stealth, and long range weaponry. they also use poisons, so it would really be anyone's call.
