There are ninjas in the world today.
They are just so good, you cant see them

Ninjas > Pirates.
Ninjas wear elite black outfits with elite throwing stars, swords, and a whole host of weapons. Only think a pirate is good at is swearing, drinking, and smelling bad. (not that I fault the swearing or drinking personally, of course)
Do pirates have Bikes named after them? NOOOO.
What pirate super hero's do you know? none.
Ninjas = Teenage mutant ninja turtles, SO THERE, NA NA NA NA NA

. even with their own tv show and everything. And they eat pizza. muahaha.
