Johnny

Johnny and Yosaku are old friends and former bounty hunting partners of Roronoa Zoro. They first appear during the Baratie arc and stay in the story until the end of the Arlong arc, both times helping out the Straw Hats. They arrive on the scene after Usopp and Luffy unknowingly shoot at the tiny island they're on for target practice. The partners had to stop because Yosaku was suffering from scurvy, but Nami was able to diagnose and treat him.

Strangely, Johnny's kanji that was tattooed onto his face remained in the 4Kids dub.

Johnny and Yasaku appear later in a filler episode (Johnny styling a mohawk, and Yosaku with a full head of hair). Their story is extended a bit as Johnny reveals he became a bounty hunter to save people and be cool, just like the bounty hunter who saved him when he was a kid. Yosaku on the other hand, just seems to want an easy life with a lot of money and little hassle. They cash in when Zoro takes out a large bounty and, given they pay his tab at the bar he was at for his food, can keep the rest of the money for themselves as an apology for taking their 'head'.
