Well i'd say The ninjas would win because the Pirates would be completely pissed. But then pirates spend a lot of time at sea so unless the Ninjas can fly or at least swim really well the Pirates would have a home advantage offshore.
it's quite a tough one.
Well lets say the Ninjas snuck onboard without the Pirates knowing (because they can) and picked them off one by one without any of the others knowing or caring (remember they're blind drunk)
damn i hate pirates, my father was a pirate, now hes dead, twas many years ago but to cut a long story short, it was a ninja who thwarted his evil schemes, thus meaning that crime never pays........ i mean ninjas RULE!!!
Hey snerlin, you should have a completely different ending about something that doesnt relate to those 2 fighters(the pirate and ninja), because those are 2 VERY good characters to have a fight against each other, it'd have to be a really REALLY nice death and hard fight, but other than that, ninja .
Ninja's of course. They master the art of ninjutsu, know ninja magic and have all kinds of tricks. They are not as good with the sword as samurai, but they have a lot of tricks.
