Quality sci fi samurai and ninja are hard to find so I've been scouring the web to compile stuff that I like. If you spot stuff that looks interesting shoot me a link as I plan to keep adding to my collection of images on photobucket.
Here's a couple examples:
Shogun of Steel comic (justice league w samurai setting)
Silent Dragon comic
Lone Wolf 2100 comic
Rifts Japan
Wildcats comic
Eden Miniatures
And of course the stormtrooper samurai
