Heracles

Heracles (ヘラクレス, Herakuresu) 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 and bombs 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.
