Ninjas & Kung Fu Part 1: Ninja Ninja Ninja!
Japan's supernaturally sneaky ninjas exploded into the world's culture in the 1980s and were quickly paid tribute in the form of cheap plastic ninja toy soldiers. The first ones to show up in the USA were made in Hong Kong and China. Some very nice ninja figures have also come out of Russia more recently. I see no reason not to include ninjas in any fantasy world. Having trouble with pesky orcs? Sick the ninjas on 'em.
UPDATE 4/1/19
I found a bag of ninjas from 1997 made by Boley that I had never seen before. They must be fairly rare. Ego aside, if I miss something like this for 20 plus years, it has to be hard to find. I also found a few of the unknown 54mm ninja that come with separate weapons that are very similar to the Marty Toy Galaxy Warriors figures.
Hong Kong/China Ninjas
Boley 1997 50mm
These guys are about 54mm if you consider that they are all bent at the knees. They actually stand at about 50mm. Four poses.
Hing Fat 45mm.
The first ninja toy soliders I found were made by Hing Fat, but were distributed by lots of different companies. These figures are about 45mm.

Unknown 54mm.
These 54mm Ninjas are just about as common as the Hing Fat figures, but I don't have any idea who made them.

Separate Weapons Variation
Redbox Return of the Ninja Playset.
This is the only Ninja playset I know of. The figures are only about 35-40mm and are a little cartoonish, but the playset is very cool.
GI Joe Copy Modern Ninjas.
These are 54-60mm copies of 3.75 inch GI Joe figures. I have no idea who actually made them.
Other Ninjas.
These are 40mm from Blip, LLC's Ninjas v. Robots set.
These were vending and prize figures. About 45mm.
These come apart the the waste. About 45mm.

Don''t know a thing about these guys other than I want some. Photo from an ebay auction.

Russian Made Ninjas
Russia is a little late jumping on the ninja bandwagon but they have made some exceptional figures.
Oritet.
Tehnolog.
Unknown (because I can't read Russian). 90mm.
Warhansa 54mm
Mattel Guts Akido Force - Close Enough.
Mattel called these guys the Akido Force, but they look enough like ninjas to me.
Greek copies.
