Oh, I see! Code names are common among the Marines, but I haven't earned one for myself, yet. [There had been nicknames reserved for the highest ranked officers and some earned for accolades corresponding to odd fighting styles, but Coby was too generic a runner to make any special name for himself. Even Garp was called 'The Fist' and 'Demon', but those weren't particularly official names.]

So, Sparky--does that mean you use electricity as a weapon? [He wouldn't have even guessed it if not for the fact that he'd seen other Marines and Pirates use it all on their own.]
