Stone

Eh, Stones a pretty cool guy, isn't afraid of backstabbing or nothing.

On another note:

Stone is stone. Stone has been Stone-ninja on the very first site ninjasandpirates.org and turned to a pirate after a while.

On the .net version of the site, stone reappeared as simply stone, stone quickly turned allegiances to pirates, and has recently turned to state.

Stone is now known as S, and generally not very well liked.
