Hey

I have an idea for a Mugen game based off of the Slayers anime, but need some recommendations for character bases.

Most of the characters will use a sword in some way so what are some good Mugen characters/sprites that use swords? I know of the Samurai Shodown series.

Also if is OK to use another pre existing Mugen character as a base? I am not too familiar with the Mugen etiquette.

Thanks for the help!
