The other 3 teams are going to be Vikings, Pandas and Matadors.

My guess for the next 3 include:
Vikings, robots, and of course, gypsies.

No you all have it wrong. The other three teams will obviously be: Zombies, Lumberjacks, and SPARTANS!

First of all, the Pirates would totally kick the ninjas assets. You know how easy it is to catch a ball with a hook? You just stick it out there and spear the sucker. And those peg legs, they can whip a mean bicycle kick with those. Not to mention all of the natural advantages afforded by scurvy, lice, and tainted grog. And parrots . . .

The only way those rice-eating, panda-loving, straw-hat-weaving ninjas would win is if the game was played in the dark. Then, they could throw out a poisoned rice-cake, sneak up behind the gluttonous pirate as he's puking his brains out and . . . oh . . . wait . . . wrong game.

For the record:

Pirates
Zombies
Knights
Ninjas
Spacemen

In that order.

Also, Zombies would be cool becaue they'd be painfully slow, but there would be a ton of them on a team, and the only way to get one out would be with a headshot.

Besides, Ninjas are a fad, they're nothing more than repurposed Samurai, with a few tacked on shurikens.

i agree pirates are waaay cooler then ninjas

It would be even better if they went with all the bad guy stereotypes:

Pirates
Ninjas
Robots
Zombies
Nazis

why do robots have to be bad?

because they attack old people.
