In L5R I briefly played a Tsuruchi archer who wanted to be Green Arrow. I teamed up with a Kaiu engineer to make trick arrows. Sadly, the game died before I could use any.
I had a Hiruma bushi who continually told tall tales of his tanuki ancestor - Pecos Bill stories reflavored for Rokugan.
I also want to play a Hida berserker type, Obtuse and as brutal and low-brow as they come, married into the Crane for political reasons. He will have two retired Kakita jesters to help him learn the ropes of civilized society. The Jesters will, obviously, be reskinned Statler and Waldorf.
