fight night.

I would have to say Ninjas in this case, because they wield "swords" and magic disappearing *poof*-- we're gone-- smokey dust bombs. Swords always win anyway! The culture of the Japanese sword lives and is never defeated =)

Even with the updates (which by the way I'm still LMAO about) I'm sticking with ninjas. While the Artificial Banana Flavoring is scarier than pirates and/or werewolves, a good shinobi would certainly dispatch ABF in a trice.
Yep, ninjas every time!

Okay, fine, now there's NO WAY ninjas can stand up to this. My pirates can BEND TIME and my werewolves have MEASLES. Take that, you sissy ninja-lovers! Pirates better start picking up some slack, or I'm gonna have to spot them some other unique powers.

The exquisite art of the Japanese sword is no match for measles!

Ninjas still win. Pirates are only pirates when they're on the sea, other wise they're just ordinary street punks and ninjas kick punk butt for breakfast. Werewolves are vulnerable to silver and wolf's bane and all the time bending in the world won't change that. Sun resistant vampires still have a lot of vulnerabilities almost too numerous to go into here. The only real problem is ABF, for which there seems to be no cure but I'm confident ninja's can take out a vile of ABF.
Ninjas every time!

See now, about a year ago I remember Pirates vs. Ninjas threads on an awful lot of message boards , and they seemed to be pretty evenly matched. Ninjas aren't as good as they have been made out to be. Shuriken are only distractions, not real weapons. Pirates have cannons, peg legs, and parrots that could poke an eye out.
