Heracles is a strange man that resides in the Greenstone forest in the Boin Archipelago. He is dressed in a beetle suit and uses a spear for combat. He saves Usopp twice, once from being attacked by a giant Hercules Beetle, and the other time from a Man Eating Plant. His attacks are apparently very fast.

He often adds "n" to the end of sentence (in Japanese). For example, He call Usopp a Usoppun, or himself is Heraclesun. He also has a habit of repeatedly introducing himself.

His name, Heracles, comes from the Greek Hero Heracles, known as Hercules in Rome, or rather from the Hercules Beetle.

First Appearance: Chapter 524
