"Plough the lilies"
The only samurai that could have been ninja were the outlaw samurai, but declining the code of honor meant that you were no longer a samurai.
Too much samurai champloo and rurouni kenshin can ruin the image...:/
Well to be fair, kenshin in rurouni kenshin was not really a samurai to begin with.A ninja can matched a samurai in a battle if he uses his dirty tricks, although fighting a samurai with a fair fight is suicide.
Oh yeah and DmC vergil is very much like batman in someways.Just like what randomlulz posted.
