Yes. They come in during the first movie. If you've seen it, then the people with the headbands with the dots are them. The ninjas Naruto's group fights, the ones that have the special armor, are snow ninjas.
Ninjas were spies and assassins, they generally wore whatever would help their disguise. They could be dressed as a farmer, a bureaucrat, a fisherman, etc. If they were on a late night dressed in black sneak attack mission they would probably wear no armor to be as silent as possible. If they were going into a frontal battle I guess they would wear whatever armor was popular and available at the time.
Spartans have better armor but ninjas are more agile.
ninjas are evidently the best; chaos ninjas are worth running right now, or you can use a blade armor ninja beatdown deck (a beatdown deck is a deck that soley relies on attacking directly with high attack monsters such as chainsaw insect etc) morphtronics are good, but chances are, you will have a bad hand, because half the deck consists of equips, and don't even start talk'in about the unicorn cards, because they are really hard to compete with the top cabiler decks, due to lack of support, consistency, and cards
It began in the ghettos of Kobe, Japan, and yes, i do enjoy ninjas! There was no art of Ninjas ninjas didn't exist
Ninjas are Warriors and Warriors are Ninjas but Ninjas would win.
Because there ninjas.

Ninjas
Only Awesome Ninjas do!
I know that females were ninjas, but it is impossible to know the percentage of ninjas were female.
Knights, because ninjas are not actually fighters. Ninjas that fight are myths. Ninjas only fight if they need to defend themselves.
